Dears, I have explored wincc OA help documentation and this portal, but unfortunately I didn’t find any way to import “.NET DLL” library, so I can call my .NET function inside wincc OA.
Is there any way to import “.NET DLL” library?
My priority is to add .NET DLL or to confirm that there is no way to add a “.NET DLL”.

If not, what is the available techniques to import external libraries “e.g. c++ library”?

You can find information for WinCC OA and C#/.NET in the WinCC OA documentation: Special functions --> C'-API.

I guess the only way to use a .NET assembly is to create a control extension.
To use a .NET assembly in an unmanaged C++ project this topic might be helpfull.

To use a C library directly in WinCC OA this topic might be helpfull.
