  • Hi Pandiyen,

    When does this exception thrown? While the Blend opening or when Blend load some project? The error message sounds like the Blend got some problem, will you try to fix it?

    If your problem still exist, you may want to ask either Visual Studio General forum or Visual Studio installation forum a better support.
