New Post: WPF Designer Extension

How do I package up a WPF Designer dll into a nuget package?

To add a designer extension you need to create a separate assembly named <Assembly>.VisualStudio.Designer.dll and place it besides te <Assembly>.dll. When I do this with nuget's <file> element into the lib folder, it adds a reference to it, which causes issues...

How do I do this?
