How to access a wpf user control hosted in a tool window

0.00/5 (No votes)

Please, help me with the following question:

first, I create a WPF user control in a WPF User Control Library project; then, I create a new visual studio add-in project, and then in the OnConnection method I call Windows2.CreateToolWindows2(...) method to create a tool window which hosts that WPF user control created in step1. here is the question: the last parameter has always been null.

According to MSDN, I set ComVisibleAttribute to true and enabled <b>Register for COM Interop</b> compiler option. But the problem is still there.

So, please help me! thanks

Why using COM interop if you're using WPF? It makes no sense. You don't need it COM visible or register. Your problem is not clear. Using a user control in XAML is straightforward. What parameter?
