Why can't Visual Studio find my WPF InitializeComponent method?

Question

This is very strange.

I have an XAML file that looks as follows...

Answer 1

I had the same problem with a Visual Studio 2010 sample project that I manually reverted to Visual Studio 2008. I found I had forgotten to set the Target Framework of the project to .NET Framework 3.5. It was empty in the project reverted to Visual Studio 2008, initially set to 4.0 in the original Visual Studio 2010 project.

To set Target Framework of a project, go to project properties, access the first tab called Application, and select .NET Framework 3.5 in the Target Framework dropdown.

Of course, I'd prefer Visual Studio giving me an error or at least a warning that I had not set my Target Framework, but hey, that's part of developing in Visual Studio, I guess.
