I recently faced the design challenge of getting an application and gadget to communicate. How to solve the problem? Well, what better way to talk between applications than Windows Communication Foundation (WCF). After all, it is the inheritor of the...

I was recently involved in some analysis of a WPF application which used 3D heavily that wasn't hitting its performance goals. The application was pegging the CPU and acted incredibly sluggish. What didn't make sense was that the CPU was getting pegged...

In my earlier post , I talked about WPF in the Sidebar by using the IFRAME to host XBAPs. In this post, I'll talk about another technique: using ActiveX. For an in depth discussion of using ActiveX in gadgets, see Jaime Rodriguez's blog post . He's got...

Check out the page on the Yahoo .NET Developer Center that shows how to databind to the Yahoo Weather Service in XAML!

If you are following Vista, you are probably aware of the Sidebar, real estate on the desktop that can be used to host gadgets. And, if you are aware of Sidebar, you might be aware that the platform for gadgets is DHTML + Javascript. And, if you are a...

AppDomains In doing some recent prototype work, the fact that WPF does not support multiple AppDomains came up. For most people, this is not an issue, but for certain scenarios, it causes some design challenges. The most common scenario for multiple...

I posted a build of the WPF Feature Montage that works with RC1. This is a great demo that walks through all the features of WPF in an amusing way, first delivered by Fil Fortes at MIX06 . He uses lots of clever techniques that are worth pilfering. Also...

If you haven't heard, all of the various pieces you need to do development on WPF are available now for RC1. A few things I wanted to chime in on: --If you haven't checked out the new Cider, do it! The XAML/Designer split view is worth downloading...

Tim Sneath walked into my office the other day and laid Charles Petzold's Applications = Code + Markup on my desk. I'm only to Chapter 7 of 31 chapters and I am riveted . I already have that feeling when reading a great novel when you don't want it to...

A tool called InvokeStress has just been posted up in the Developer Tools area on the wpf.netfx3.com site by a tester from the WPF team. This tool is amazing: it uses UIAutomation to randomly click any UIElement every three seconds. It is a great way...

If you are doing development of browser-hosted .xbap WPF applications, there can be some confusion and delay when you want to clear out the cache. If you have the .NET SDK on the machine, you can run the mage program with the following switch: mage...

This has been out for awhile, but I thought it was so well done that it is worth installing. Check out Mobileware's Big Screen Photos -- pretty cool Flickr implementation for MCE using WPF.

Ever get this? System.Windows.Markup.XamlParseException: Unexpected end of element when parsing an object. BAML stream might be corrupted. This flummoxed me for quite awhile, until Eric Burke (whose blog is heating up...) realized by deduction that...

Been porting a lot of code lately and the support for runtime XAML debugging to get line numbers has been essential! Just add this to your .csproj or .vbproj file: <XamlDebuggingInformation>true</XamlDebuggingInformation> Thanks to Nick...

How would you like to create assets in Graphic Designer and apply them to your WPF applications in Expression Interactive Designer without ever touching a line of XAML? With some new features in the May 2006 CTPs of EGD and EID, you can do this. This...

Up on the Expression blog, a fantastic tutorial that isn't in the docs yet has been posted . I just walked through the entirely thing step-by-step and it is probably one of the best resources out there for unlocking the power of EID and WPF. It explains...

Nathan Dunlap , WPF designer extraordinaire, put together a fantastic screencast and code sample that shows how to create workflow between Expression Interactive Designer and Visual Studio. Nifty stuff like creating a .dll in VS with dependency properties...

How did I miss this? Daniel's show on 3D Integration in Windows Presentation Foundation is really nice. Even better, he shares some great code samples , which indirectly lead me to http://viewport3d.com which has a nifty article -- nice domain name snag...

At this point, with the amount of great content online (and free), it is possible to train yourself on WPF. But where to begin? There are a ton of links, blogs, documents, screencasts, videos and more -- so much, in fact, that beginning can be daunting...

Wikis are only as good as the contributors, but the new MSDN wiki is already shaping up to be quite good. There isn't any of the .NET 3.0 docs up there yet, but if you going online to get information about .NET 2.0, I'd go here so that you get both the...

I have uploaded Sandbox3D into the WPF Gallery. I added back the X, Y and Z axes using ScreenSpaceLines3D from Daniel Lehenbauer. Most interestingly, I show two different techniques for mapping video on 3D. One is using the VideoDrawing with a MediaPlayer...

Karen Corby has published a template for Visual Studio that allows you to seamlessly switch between compiling for a standalone application and compiling for an .xbap. Even more nifty, she has added support for conditional compiles in both code and XAML...

The WPF animation capabilities are powerful, but a bit opaque. EID helps, although in its current pre-beta state it only unlocks so much of the system. Animation begs for more abstraction and it was only a matter of time before someone did it. Check out...

Now that the WPF Community Site is live, I'm migrating all my samples to there. So, the first one is up: Monkeys Jumping . Another handy feature is the blog aggregation of both Microsoft WPF bloggers and active non-Microsoft WPF bloggers . This site will...
