ERROR: The path is not of a legal form.

I started getting this occasional error. Usually it goes away when I rebuild. Any idea why this is happening

ERROR: The path is not of a legal form.

    From the error information (System.IO), this looks more like a problem with .NET Framework, and not something specifically VSTO. Difficult to say, though, without seeing the code that's causing the problem. The best place to get help tracking this down is probably the .NET Framework Base Class Library newsgroup, where they deal with the System.IO classes. I'm moving your question there. Please post the code that's causing the problem as a follow-up to your message.

    I don't know what code is causing the problem. If someone has access to the VSTO and .NET Source code can refer to the stack trace that I posted in 1st message.

    This error occurs sometimes when I open the solution, and sometimes when I build it. Most of the time it goes away when I rebuild the solution.
