Why can VS not display my WPF application in the designer, but it can run it just fine?

This is absolutely ridiculous! Visual Studio is able to run (debug) my program just fine, but it won't display my layout in the designer. It just gives this useless error:

Can anyone help explain this? I have not changed the XAML at all, not a single character, since the last time it worked fine. I've only changed some .cs code.

Have you tried Expression Blend? It has a better design view, you can edit the cs code (though the Intellisense is limited) and you can run the debugger.

While it's not a full replacement (it's not meant to be) it does mean you don't have to continually swap between Blend and Visual Studio if you're just modifying the UI.

This sometimes happens when the application must use some data that is gathered at runtime to render properly. I've had this problem when my controls are bound to data in a web service.

because VS is cripple in terms of Xaml editing. Just turn off that designer, http://www.thejoyofcode.com/Using_the_Source_Code_Editor_for_XAML_in_Visual_Studio.aspx

See this: XAML Designer failing to render - UserInitiatedNavigationPermissio

Basically, that looks like bug that is fixed in Visual Studio 2008 SP1. If you already have SP1, then run repair installation of VS2008 (go to Add/Remove and then select Repair option)

Have you tried doing a rebuild? In the past I have noticed that this happens if the compiled code is out of date.
