XSLT debugging is getting tantalizingly close (see image below). Yes, that button tool-tip DOES say “debug” and that IS a break-point in the left-hand margin. The only problem is that when I press said button I get a XmlQueryException, with an inner NullReferenceException. Is anybody else having these problems debugging XSLT in the Tech-Ed CTP release of Whidbey, or is it just me? The transform does produce valid output (when I click the “show XSL output” to the left I see the output in TestFile1.xml). I might try and create a compiled xslt with a .pdb file and see if I can debug it that way.
