Why are Cdecl calls often mismatched in the "standard" P/Invoke Convention?

Mar 27, 2013 See the question and my original answer on StackOverflow

cdecl and stdcall are both valid and usable between C++ and .NET, but they should consistent between the two unmanaged and managed worlds. So your C# declaration for InvokedFunction is invalid. Should be stdcall. The MSDN sample just gives two different examples, one with stdcall (MessageBeep), and one with cdecl (printf). They are unrelated.
