No creation of a WPF window in a DLL project?

Question

Is there a reason why Visual Studio won\'t let me create a WPF window in a DLL project?

I \"solved\" it by creating a window in an Application Project and copying it

Answer 1

Make sure the project type is WPF User Control Library when you create your project.

If it isn't then no sweat, just edit the csproj file and make sure the element under Project/PropertyGroup contain the following GUIDs

{60dc8134-eba5-43b8-bcc9-bb4bc16c2548};{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}

Also, make sure you reference PresentationFramework and System.Xaml in your project, or you will not get any WPF in your code.
