I have a C# project that uses DLLs that are coded in Fortran wrapped in C++. I have been sucessfully using these project in VS2005, but I needed to upgrade the C# to VS2010. After doing this upgrade, I can no longer debug into the Fortran part of the DLL (I can still debug into the C++ that wraps it). At the point where I step into the Fortran, a tab for the Fortran code opens up, with the name of the file on the tab, the cursor turns to an hourglass for about 5 secs, then VS2010 becomes unresponsive. No code ever shows up in the tab (the tab interior is a solid blue). At this point I have to shut down VS2010.
I get no error messages. I have tried recompiling the DLL using VS2010, with the same result. I am using IVF 2011.10.325 in the VS2010. Any suggestions?
