Expression Blend: Getting error “XXX” does not exist in the namespace “XXX”, but not in VS2008

Question

I am trying to use Blend 3.0 to edit a project that contains some WPF controls. This project already compiles and runs fine from Visual Studio 2008.

In Blend however

Answer 1

I think that Blend uses the default config/platform defined in the project file. You should be able to fix this by editing it with a text file. If you look in your .csproj file, you should see something like this:

    Debug
    AnyCPU
    ...

Change that AnyCPU to x86 and it should work the way you expect.
