So I was upgrading a project from VS.NET 2003 to VS.NET 2005 (v2.0 of the framework) and I kept hitting this assert: "_CrtIsValidHeapPointer(pUserData)." There were several postings out and about but they were all for previous versions of the framework, nothing to do with upgrading to whidbey. After a long and unsuccessfull jaunt to change my C++ syntax from /clr:oldsyntax to just /clr along with many other now forgotten changes, I made the following project change:
I changed the code generation property of "runtime library" from /MDd to /MD...and voila, gone! Hopefully this tidbit will save someone an afternoons worth of work!
Now I get to go stand in line at BestBuy this weekend and hopefully acquire a XBOX 360. [:D]
