The 'clr-namespace' URI refers to a namespace that is not included in the assembly

Question

I\'m trying to include in my XAML some classes which convert values. However, I\'m getting the following error when I compile:

Undefined CLR namespac

Answer 1

I figured out what was wrong. Although visual studio showed this as the first error, there were indeed other errors with my coding which prevented the converters from being assembled. Thus, when VS went to find the assembly, it was not there.
