I have just upgraded my project to Visual Studio 2012 and I added a new SF user control to the project.  While working on the SF user control,  I am periodically getting the attached error in the designer.  To clear the error I have to exit out of the VS 2012 and reload my project.  Why am I getting this error?

Thanks,

Jeff

I used to get lots of these all day long a while ago. At one point, I put together a new box with Win8 and VS2012 and since then I have never had any issues. On my old machine, it started after I upgraded from VS2008 to VS2010 I think. The environment probably has some effect on this, but I was never able to find out the culprit.
