Question

I have an error that not let me see my designer.. but I have no error on a build and my program runs fine with no problem

I have tried to:

• Clean and Rebuil

Answer 1

I was able to get rid if this problem in the past by adding the actual assembly name to the namespace reference like this:

xmlns:windowManager="clr-namespace:PulserTester.Convertors;assembly=TheNameOfTheAssemblyWithoutExtension"

This has worked for me in the past.
