Happy new year to all members of the Wolfram community.

I am learning how to call dlls from Mathematica since I want to use tools developed in the electric distribution analysis. I have started with the very common example that add to real numbers. I have generated the .dll in Visual Studio and C#. I had no troubles to generate the dll. However, I had several issues while loading the required .NEtLink. I did this

Needs["NETLink`"];InstallNET[];

I got the following errors

I thought MathLink was part of my Wolfram Desktop bundle. I is not?

Hope someone can help!
