I changed the dll in an attempt to get the designer to show my control with AutoSize set false and ended up with a thrown exception in the designer.

问题 The summary of my problem: I had created a UserControl where I bound my dependency property "Scheme" to the Color property of a GradientStop , and it worked perfectly.
