C++ vs. C#

[C++ Programming]

Hi All.

I have a simple question...

Lets say I have a C++ DLL with one exposed fucntion.
Now, If this fucntion get called from C++ Source code OR from C# Source code, then do we any difference on the basis of calling ********, as far as performace of this DLL[exposed function] is concerned?

In case you need any further information, please let me know.


Thanks
