XmlParseException in Expression Blend 4

Mar 24, 2011 at 3:32 PM

I'm getting XmlParseException Line 0 Position 0 in expression blend when it tries to load the SMF Player.  Stack track is indicating a problem with MeasureOverride.  This problem does not happen in Visual Studio 2010.  Sometimes I can get around the issue by deleteing my references to the SMF dll's and readding them.  Other times I just have to comment out the player until I'm done editing with Blend.  Any ideas on this?  The xaml does show the player briefly for a few seconds but the UI is still busy doing something and then the exception pops up once the UI is idle.


Thanks, Andy
