  9. Destructors not called when native (C++) exception propagates to CLR component

    We have a large body of native C++ code, compliled into DLLs. Then we have a couple of dlls containing C++/CLI proxy code to wrap the C++ interfaces. On top of that we have C# code calling into the C++/CLI wr...Learn More
