Questions about integrating Mathematica and .Net using the .NET/Link functionality provided with Mathematica.

Using the .NET/Link product, it is possible to integrate Mathematica and .Net, either calling Mathematica from a .Net application, or a .Net application/DLL from Mathematica.

Possible use cases include loading some specific function into Mathematica that is faster in C#/.Net than in pure Mathematica code, or building a user interface in .Net that integrates with Mathematica’s calculation capabilities.
