• Visual Studio VS IDE crashes when debugging in managed or mixed mode

  I have a c++ project that uses a .NET 1.1 assembly as a com object. It is loaded with CoCreateInstance. If I debug in native mode it looks like everything works okey, in managed mode the application crashes with no errors or anything, and in mixed mode Visual Studio crashes.
