You don't need to create COM interface to use application in C#. It is better to create managed interface to .NET - An Overview of Managed/Unmanaged Code Interoperability

We already have our library with many Pro/Toolkit functions which we are using in C#

Hi Parthiban Kanna

Can you please guide me how you have achieved the same?

[TomasLoun]

Yes, have you already started with the article I have mentioned?

Hello Yogesh,

         SImply I have exported dll using extern "C" in toolkit coding & directly loaded it into my C# Program instead of add reference method

[TomasLoun]

Can you post how your makefile looks like? You have probably some problem in linked libraries...

Hi Tomas,

    I have moved to win32 dll application instead of makefile project.
