I noticed that the documentation for GetFunctionPointerForDelegate
states that "The delegate d is converted to a function pointer
that can be passed to unmanaged code using the __stdcall
calling convention."

I would have expected that method to honour the
UnmanagedFunctionPointer attribute decorating the
delegate declaration.

Does this describe the actual behavior or is it just
a documentation bug? AFAIK, both the function and the
attribute were newly added in .NET 2.0.

That's the default behavior of the 'naked' method.

It does honor the attribute.

Not a bug, it does describe the functions behavior, it would help if the
remarks section would refer to the UnmanagedFunctionPointer however.
