MSDataSetGenerator in VS2008 Beta 2
If you're running VS2008 Beta 2, you might have come across a problem with MSDataSetGenerator (the standard custom tool for generating DataSet code from XSD schema). It manifests itself as an error message that occurs when trying to run against XSD that <include>s other schema. (Note, xsd.exe seems to generate code just fine - it is only the custom tool inside of VS.)
There's a simple fix, though - install the August CTP of Blend 2 on your machine, and all will miraculously become well.
