WPF is a .NET Core UI framework for building Windows desktop applications.

Folders and files

Repository files navigation, windows presentation foundation (wpf).

Windows Presentation Foundation (WPF) is a UI framework for building Windows desktop applications.

WPF supports a broad set of application development features, including an application model, resources, controls, graphics, layout, data binding and documents. WPF uses the Extensible Application Markup Language (XAML) to provide a declarative model for application programming.

WPF's rendering is vector-based, which enables applications to look great on high DPI monitors, as they can be infinitely scaled. WPF also includes a flexible hosting model, which makes it straightforward to host a video in a button, for example.

Visual Studio's designer, as well as Visual Studio Blend, make it easy to build WPF applications, with drag-and-drop and/or direct editing of XAML markup.

As of .NET 6.0, WPF supports ARM64.

See the WPF Roadmap to learn about project priorities, status and ship dates.

WinForms is another UI framework for building Windows desktop applications that is supported on .NET (7.0.x/6.0.x). WPF and WinForms applications only run on Windows. They are part of the Microsoft.NET.Sdk.WindowsDesktop SDK. You are recommended to use the most recent version of Visual Studio to develop WPF and WinForms applications for .NET.

To build the WPF repo and contribute features and fixes for .NET 8.0, Visual Studio 2022 Preview is required.

Getting started

• .NET 6.0 SDK , .NET 7.0 SDK
• .NET Preview SDKs (8.0 daily, 7.0 servicing)
• Getting started instructions
• Contributing guide
• Migrating .NET Framework WPF Apps to .NET Core
• We are currently developing WPF for .NET 8.

See the WPF roadmap to learn about the schedule for specific WPF components.

Test published at separate repo Tests and have limited coverage at this time. We will add more tests, however, it will be a progressive process.

The Visual Studio WPF designer is now available as part of Visual Studio 2019.

How to Engage, Contribute and Provide Feedback

Some of the best ways to contribute are to try things out, file bugs, join in design conversations, and fix issues.

• This repo defines contributing guidelines and also follows the more general .NET Core contributing guide .
• If you have a question or have found a bug, file an issue .
• Use daily builds if you want to contribute and stay up to date with the team.

.NET Framework issues

Issues with .NET Framework, including WPF, should be filed on VS developer community , or Product Support . They should not be filed on this repo.

Relationship to .NET Framework

This code base is a fork of the WPF code in the .NET Framework. .NET Core 3.0 was released with a goal of WPF having parity with the .NET Framework version. Over time, the two implementations may diverge.

The Update on .NET Core 3.0 and .NET Framework 4.8 provides a good description of the forward-looking differences between .NET Core and .NET Framework.

This update states how going forward .NET Core is the future of .NET. and .NET Framework 4.8 will be the last major version of .NET Framework.

Windows Presentation Foundation

The Windows Presentation Foundation (or WPF), formerly code named Avalon, is the graphical subsystem feature of the .NET Framework 3.0 (formerly called WinFX) and is directly related to XAML. It is pre-installed in Vista, the latest version of the Microsoft Windows operating system. WPF is also available for installation on Windows XP SP2 and Windows Server 2003. It provides a consistent programming model for building applications and provides a clear separation between the UI and the business logic. A WPF application can be deployed on the desktop or hosted in a web browser. It also enables richer control, design, and development of the visual aspects of Windows programs. It aims to unify a host of application services: user interface, 2D and 3D drawing, fixed and adaptive documents, vector graphics, raster graphics, animation, data binding, audio and video.

WPF/E is a subset of WPF, and stands for "Windows Presentation Foundation Everywhere". It is basically a mobile version of WPF, based on XAML and Javascript. 3D features are not included, but XPS, vector-based drawing, and hardware acceleration, are. Wikipedia

This site was created in 2006. It was dedicated to everything Windows Presentation Foundation. Andrew Whiddettt (CTO), Victor Gaudioso and John Woo are WPF Engineers who helped guide those so inclined to learn WPF via articles, blogs, downloads and tutorials. Each of these engineers had their own blog.

An Update: I wonder how these three engineers would have reacted to the news that Zendesk was going to kill its Windows Phone app in 2017. I work for a company that offers customized help desk support to Zendesk clients. Our phones were ringing like crazy when this announcement was first made. Zendesk is a global provider of customer service software. They operate in 150 markets. In 2012 the company launched its Windows Phone app in the Market. However in November 2016 Zendesk announced that it was going to end support for its Windows Phone app and the app would only receive any emergency maintenance updates after Dec 31st 2016. Arggg!!! went our clients. In 2017 we had to explain to clients that due to the low usage of its Windows Phone app, Zendesk was just going to kill it. The app was removed from the Windows Store completely in April 2017 and was no longer be available for download for Windows Phone users. It was understandable if Zendesk didn't have enough users to justify making the proper updates and support. We told customers that Zendesk recommended they switch to an iOS or Android OS platform to keep enjoying the features of its Zendesk App. We also offered other work-a-rounds, but some clients were initially very unhappy. I was burned out by the end of that week. My one consolation was that the company just happened to be upgrading our offices and the reception area that same week with Italian modern furniture that was really sleek and cool. The furniture company, room service 360°, they ordered from is located in Philadelphia. I've driven by it many times but never associated it with business furniture. Turns out room service 360° offers stunning modern furniture from many Italian brands among others, for both the home and office. The makeover of the company was impressive and had a very positive impact on the employees moral. And the feedback from both our old and new customers was irrefutable: They loved the new look. Thank you management.

Now it's time to hit the road and drive home. I always like getting home. My affectionate Alaskan Malamute, Nanette, greets me at the door, ready to have some fun. We have a routine that includes a three-mile run and playing frisbee, a game she loves. Nanette is surprisingly agile for such a large dog, and catching that frisbee is her favorite part. It's a good thing I have several acres of land for her to use up all her energy before we go in for the night. Speaking of hobbies and outdoor activities, I recently got into golf, inspired by the themes of this year's Forum, which emphasized wellness and personal growth. Just last week, I picked up a Tour Edge golf club , a brand recommended by a friend. This club has been a fantastic addition to my leisure time, providing a great way to relax and improve my game. I'm planning to spend more time at the local golf course, honing my skills and enjoying the open spaces, much like Nanette enjoys her time outdoors. This evening, after our run and frisbee game, I might even practice a few swings in the backyard. It's going to be a good evening, indeed. Oh yes.

The LASLUG Raffle Chooser App has been Published in the Windows Phone 7 Marketplace

Victor @ 1:57 pm

If you attended our May 25, 2011 Los Angeles Silverlight Usergroup (LASLUG) meeting then you saw Kim S (LASLUG Special Event Coordinator) use the custom built Raffle Chooser Windows Phone 7 Application to choose the Winning Raffle Tickets.

Well, I figured that this could be a handy tool for our other .NET Usergroups such as LA C# Usergroup or even our friends at SoCal Code Camp ran by Woody

Pewitt (@woodyp on Twitter) as I think they all hold raffles as well. So I published it on the Zune Marketplace.  It is under the Social Category and is FREE!

You can Install the Raffle Chooser app directly from here: http://tinyurl.com/4xhcltr

If  you would like the source code feel free to email me at victorg at laslug dot com.

Thanks!  Victor

The Los Angeles Silverlight Usergroup (LASLUG) is Growing by Leaps & Bounds – State of the Usergroup

— Victor @ 12:07 am

Hello LASLUGers!

Today we had an occurrence that sets us apart as a premier .NET Usergroup;  today we hit the BIG TIME: Telerik has signed on to become a proud sponsor  of the Los Angeles Silverlight Usergroup.  In their own words, Telerik’s Emily Parker writes “ (we) provide 1 Telerik Ultimate Collection valued at $1999/month. This license is our largest bundle so it includes tons of software – check them out here: www.telerik.com/purchase.  I know you said other’s do two licenses/month but this license is a  huge bundle which always goes over well.  We send a demo CD with the license codes on them so your winners can just walk away with this and they are all set! “  

 Are they awesome or what? 

 Mission Statement:

To provide the local Los Aneles .NET community (with an emphasis on Silverlight & WPF) with the finest speakers that the planent has to offer.  Further, we pledge not to ever charge any of our members any money for this service.  While most other usergroups are free to attend they tend to charge for the raffles whereby they give away prizes.  We not only offer free gourmet pizza, beer, softdrinks and deserts we offer free prizes.  It is our goal to provide every member in attendence with a free prize be it a small prize such as a DevExpress tee-shirt, or a Microsoft Flash drive to something more significant such as an Apress book on how to do game programing for Windows Phone 7 to something very expensive such as Telerik’s Ultimate Silverlight Software Collection (a $1999.00 value).  Further, we promise to update our venues to make it easier for some members to attend one month and then easier for other members to attend another month.  We also feel this keep the group fresh and reduces the chance of them becoming bored with LASLUG meetings.  Finally, we have commited to our sponsors to help them add to their customer base by touting the positive aspects of their products and by encouraging our members to use their decision-making power at their places of employment to employ these books and tools if they enjoy the products we give to them as prizes. We also promise our sponsors high-visibility on our website (www.laslug.com) as well as in our meetings.

So Wed May 25th is the tentative date for our next  LASLUG  meeting and the first meeting we will be giving away  Software  from:

1.  Telerik  (one copy of Ultimate Collection – Value: $1999.00);

2.  DevExpress  (two copies of Silverlight Controls for Silverlight – Value: $799.99 (times two));

3.  Syncfusion  (two copies of Essential Studio Enterprise Edition – Value: $1,995.00 (times two));

4.  VIBlend  (VIBlend WPF Controls package – Value: $349.000), (VIBlend Silverlight Controls package – Value: $499.00).

We will also be giving away books:

1.  Apress  - Four titles to be determined – Approximate Value: $50.00 (times four));

2.  FreindsOfEd -  One title, two copies - Expression Blend 4 with Silverlight – Value: $49.00 (times two));

3.  Safari Books Online  (10 day free trial and 20% off with purchase of a year subscription).

We will also have swag from:

1. Mircosoft

2. DevExpress

3. Syncfusion

This comes out to a total of  $9,283 .  So by the time the meeting takes place I expect the prizes to be valued at  well over $10,000 .

And this is just as of right now…we are currently in talks with  O’reilly, Manning, Anheuser-Busch, New Belgium Brewers  and a few others.

So look for email blasts from me and the management team with regards to new sponsorship and meeting details.  Once you get the meeting announcement please secure your spot  ASAP  as space is limited and I think that will all of these new  prizes ,  swag ,  gourmet pizza  and  beer  the meeting is going to fill up  fast!

An Amazing Review of my new Silverlight 4 Book

—  Victor @ 12:26 am

A reader named Peter Henry wrote an awesome review of my new Silverlight 4 book on his blog.  Its funny, the way he describes my writing style is EXACTLY what I was shooting for;  that is, as if I were right over your shoulder telling you step by step how to develop in Silverlight using Blend and Visual Studio.  Here is his review, you can also read it here: http://www.pchenry.com/Home/tabid/36/EntryID/343/Default.aspx

A few weeks ago, I saw a message on Twitter asking people to reply to get a free book.  Now, usually I disregard those emails/phone calls/unsolicited advancements with utter and complete contempt (too polite? LOL) but this time around I thought I might read this a bit further.  

The posting was from Simon Yu from apress.com, he was asking for reviewers for an upcoming Expression Blend book.  Interesting.  I was familiar with the previous book (Expression Blend 3) since Sylvain had bought one last year and I was kind of envious he was learning WPF and Expression Blend with this book.  Ya, it looked that impressive when I leafed through it.

But then……..life got busy, work got busy…..life just happened…..you probably know what I mean right?  Well, fast forward to Simon’s posting and I thought, eeehhhhh……what’s the worst that can happen?  Oh ya, he could be bogus and I get spammed forever?  AAAAAHHHHH let’s try it out, could be interesting?

As I would say to Bert lately, “long story short”, I got the book in the mail (thank you very much Simon!) and I have to tell ya, WOW!!!!!!!!!!!!  VERY COOL!  I guess in the last year, I’ve kind of gotten a bit gun-shy with the whole WPF/XAML/Blend thing.  Why?  Not quite sure why actually…..just that there’s A LOT to bite off to get something done.  Layout managers, data binding, POCOs or EF, WCF or web services, resources, triggers, behaviours, then there’s the whole XAML and Blend thing…..maybe you’re where I am?  You feeling a bit OVERWHELMED with all that?

Well, this is where this book comes into play.  I said to myself, with WP7 coming out, I’m getting on that band wagon and I’m going to do WPF this time!  Yes siree Bob!  Who’s Bob?  I don’t know, that’s the expression!  Anyways, here are my first impressions!

• Who’ the book aimed at?  People like me!  COOL!
• It’s NOT 800 pages!
• It reads less like MSDN and more like a book that keeps you excited!  Sorry MSDN, no slight against you, when I goto you, I want info HERE AND NOW, nothing pretty, nothing fancy, but when I’m reading about something brand new, I need a bit of spoon feeding and a bit of excitement to keep me interested.
• “LOTS of pretty pictures!”  Which is good for a visual designer tool that Blend is!  Ironic eh?  Lots of sites, even books don’t have pictures, WTF?  The HUGE benefit of pictures is I can see IMMEDIATELY when I’m begining to deviate away from the lesson and starting to get lost.  Not here!
• Juicy info is had right away, not half way through the book.  Ever read a Tom Clancy book?  Doesn’t matter which one, they ALL, only get interesting half way through.  Boooooooring!  Not with this book!
• Yes, I did get the book for free, but NO I’m not biased nor inclined to give this book a good rating just because of that.  I’m cheap, but I’m also not looking to make my living with book reviews.  I have ONE objective with this book, to learn Blend!
• And my last, first impression, which is the most important point in this post, Victor’s writing feels COMPLETELY interactive and dynamic.  Think about it, it’s a book written months ago, and it STILL feels like a conversation with him right there!  What do I mean?  He does this a lot and I love it…..he explains something, and I’m thinking…but, but but……then in the very next sentence he answers my very same question in my head.  Ya, and he does that continuously.  I’ve done good and bad training courses before, this guy writes this book like a beautiful training course.  I’m 50pgs into it and have HUGE expectations now for him to continue doing his “set’em up and knock’em down” style of teaching!

So, there you have it, my first impressions about this new book from Victor Gaudioso.  Keep your eyes peeled on this blog for a followup blog with my end of book review.  Now it’s time to grab a coffee and get coding (well, reading and coding that is LOL).

Thanks so much Peter!  Victor

An Interesting Journey with a Man Named Ted

— Victor @ 8:24 am

As you probably know,  I am very serious and passionate about my love for Silverlight and Blend; I love the technology and possess a burning passion for teaching it.  If any of you know me you know full well that if you ask me for help I will do all I can to help you understand this medium and to be productive in it. 

As you also know I write books on Blend and Silverlight; I do so for a couple of reasons:

First, I do it to help those interested to learn this platform.  Silverlight and Blend are amazingly easy to use once you know how.  Sadly learning how can be difficult.  To facilitate the ease of learning this medium I decided to write books under the Apress/Friends of Ed flagship  Foundation  series.  I have two books already published and currentlyI am writing my third on SL 4/Blend. 

The second reason I write books is so that I have creditability as a bonafide  SL/Blend expert.  That being the case people will listen to my teachings and when I raise issues to my friends over at MSFT I get some very good responses. 

What I  DON”T  write these books for is money; it is all about the passion I possess.  To be honest, I don’t make a whole lot of money writing these books; if you were to break it down I probably end up making less than $5.00 per hour. 

So, whenever I receive a new review on Amazon I am quick to read it in hopes to understand how the public feels about my publication and how I can improve my next book.  As an example of this, I have my book’s Amazon link on my smart phone’s desktop. I click it at  least  once per day to look for new comments. 

The comments thus far have been quite positive (currently the book has 4 out of 5 stars).  So, whenever I get a negative comment my heart sinks and I am deeply saddend and concerned. 

As it happens just such a comment came down the pike a few days ago. In this review a man named Ted stated that there is entirely too much code in my book and being that it is a Blend book this should not be the case. 

While this review did hurt my feelings I had to admit the guy had a valid point.  But to be sure I grabbed a copy of my book and started to thumb through it and this validated what he had stated: there was in fact too much code for a Blend book.  So, I commented back and told Ted that his comment “ cut me to the core ” and that he did in fact have a valid point.  I apologized and promised that I would do better on my new book slated to come out this summer. 

Ted quickly responded and was a little apologetic that he had hurt my feelings but stuck by his point. He accepted my ap0logy and said that he looked forward to my next book.  But I didn’t feel that I had done enough for Ted.  Sure I had helped him understand that there are real people behind these books that have real feelings but what had I done to  help him?  This was a reader that put his faith in me to help them learn Silverlight and Blend and I had left him wandering aimlessly in the woods.  Not cool! What to do?

So, I decided that Ted would be one of those readers that is smart enough not to need to be guided through a narrative on how to learn Silverlight  and Blend.  After some thought it hit me that Ted is one of those that would benefit from a “ take one from column A and one from column B ” kind of learning regime. 

With that, I pointed Ted at my  personal blog where I have about 30-40 free Silverlight video tutorials.  They range from “ how to build a chrome button in Blend”  to “ how to de-serialize XML into native Silverlight objects .”

The danger of pointing a Silverlight newcomer to these videos is there is no structure, the reader is free to run wild and possibly tutorialize themselves into total confusion. 

Which, by the way I think my beginner books are great:  I take your hand at the very beginning and then walk you through, step by step how I think you should learn Silverlight and Blend and then when I think you are ready I let your hand go and tell you to now go forth and learn, you are ready.

So, this morning I received an email from a very excited and happy Ted telling me that my videos are what he has been looking for since he started this mission to learn Silverlight/Blend some 15 days ago.  Further, he was so satisfied he was compelled to post a comment entitied  “Must Watch – Must Read Resources for Blend!”  on the Microsoft Expression website, found  Below are a couple of excerpts from his post:

“…He explained things I had not seen in any help files or any other videos in 14 days of research.  You might be tempted to skip the first video about the UI, don’t do it!  One of the HUGE keys to understanding Blend is understanding the interface….”

“…Trust me, if you watch Victor’s videos, you will have about 50% fewer questions on how to do things in Blend.  If you work through the self paced tutorial, you will have another 50% reduction.  Just think, you will actually be able to do something in Blend, not wait for answers here, and when you DO have a question, it will probably be code related or something pretty esoteric that these experts can really sink their teeth into!…”

So now I have fulfilled my goal of helping one more person who wants to learn Silverlight and Blend.  And along the way, I discovered a way to make my new book better and even made a friend along the way.  Thanks Ted, my friend.

This is actually my first week of WPF and it has been a frustrating one as it is very difficult to install the WPF authoring environment. The reason for this is because MS has not released the final build for WPF as of yet. So, in order to install the authoring environment you have to install a few different things. They are:

  1. The .NET 3.0 Framework (if you have .NET 2.0 framework it might be best to uninstall it first.

  2. Visual Studio 2005 (Visual Studio Express is free and should work).

  3. Orcas.

  4. MS Interactive Designer (formally known as Sparkle)

  5. Visual Studio Extensions (so you can create a WPF project).

This should get you up and running. Soon, I will post a blog about creating a very simple WPF application. However, in the meantime I would suggest you get Jesse Libery's and Brian MacDonald's book on C#, called C# 2005 and Jessey Libery's book called, ironically enough C# and brush up on your C#. Good luck. Victor

Today I am posting my first WPF application. It is simple but I think it does show the power of the WPF 3D engine. If you have trouble seeing it you may have to download IE 7. Soon, I will post a tutorial on how I built it; you will be amazed on how simple the code for this was. Victor 

I have been in WPF bootcamp for the last three weeks and have learned quite a bit. Soon, I will post tutorials on how to style buttons as well as how to make a simple video player. Keep checking back. Victor 

We have written an exporter for 3DS Max so I have been learning the basics of that program. I made a simple model of a lightsaber with a simple rotation animation and exported it to XAML. Take a look:

Blend Beta 2 is out. I don't know if you have used this but this is awesome for the design side of WPF. I still use Visual Studio for the C#.

WPF Host (PresentationHost.exe)

• 2 contributors

XBAPs require legacy browsers to operate, such as Internet Explorer and old versions of Firefox. These older browsers are usually unsupported on Windows 10 and Windows 11. Modern browsers no longer support the technology required for XBAP apps due to security risks. Plugins that enable XBAPs are no longer supported. For more information, see Frequently asked questions about WPF browser-hosted applications (XBAP) .

Windows Presentation Foundation (WPF) Host (PresentationHost.exe) is the application that enables WPF applications to be hosted in compatible browsers (including Microsoft Internet Explorer 6 and later). By default, Windows Presentation Foundation (WPF) Host is registered as the shell and MIME handler for browser-hosted WPF content, which includes:

Loose (uncompiled) XAML files (.xaml).

XAML browser application (XBAP) (.xbap).

For files of these types, Windows Presentation Foundation (WPF) Host:

Launches the registered HTML handler to host the Windows Presentation Foundation (WPF) content.

Loads the right versions of the required common language runtime (CLR) and Windows Presentation Foundation (WPF) assemblies.

Ensures the appropriate permission levels for the zone of deployment are in place.

This topic describes the command line parameters that can be used with PresentationHost.exe.
