This is absolutely ridiculous! Visual Studio is able to run (debug) my program just fine, but it won't display my layout in the designer. It just gives this useless error:

Can anyone help explain this? I have not changed the XAML at all, not a single character, since the last time it worked fine. I've only changed some .cs code.

In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
