Using Visual Studio to debug XSL

So I was attempting to debug an XSL stylesheet and every time I attempted to debug it, I would continually get the following error:

Visual Studio encountered an error and will restart.

I looked high and low, to no avail.

The solution(s) are (one or the other)

• Disable Visual Studio 2010 Power Tools
• Move the xsl into a c# project instead of a BizTalk project
