Answer / narayansahu

you can only write unmanaged code in c# not in vb.net
you can only call unmanaged code in vb.net. calling and
writing unmanaged code are different things.

To identify whether the code is managed or not open the
file in ildasm in VS.Net Command prompt.
Also you can use a .Net tool called dumpbin, which can be
used to check the headers.

or open the dll in notepad and check for "V e r s i o n".
If you find that, it is managed assembly.
