C# IDE Problem...

Question

I don't know if this is the right place, but I seem to be having a problem with the "Add New File" dialog, in Visual C# (IDK if this is tied to the rest of Visual Studio though).  When ever I try to add a new file from the solution explorer, or anywhere for that matter, I get this lovely error message:

I don't know the cause, and it was working fine 5 minutes beforehand.  I tried restarting, etc. Any help?

Answer 1

This would indicate an issue with instantiating an instance of the WPF FlowDocumentScrollViewer control on a window.  What item are you trying to add to the project and what type of project is it?

Answer 2

It occurs whenever I try to open the "New Item" dialog.  But the specific item I want to add is a class, though this does occur every time instead of the actual dialog opening.  The project is an XNA 4.0 Windows Game Library, but this error does occur everywhere else in VStudio.

Answer 3

It sounds like your installation has been corrupted.  Try uninstalling XNA, repairing the VS SP1 installation and see if the problem goes away.  If it does then reinstall XNA and see if the problem comes back.
