Question

Suppose I am writing an application in C++ and C#. I want to write the low level parts in C++ and write the high level logic in C#. How can I load a .NET assembly from my C++ program and start calling methods and accessing the properties of my C# classes?

[Guid('123565C4-C5FA-4512-A560-1D47F9FDFA20')] public interface IConfig {     [DispId(1)]     string Destination{ get; }      [DispId(2)]     void Unserialize();      [DispId(3)]     void Serialize(); }  [ComVisible(true)] [Guid('12AC8095-BD27-4de8-A30B-991940666927')] [ClassInterface(ClassInterfaceType.None)] public sealed class Config : IConfig {     public Config()     {     }      public string Destination     {         get { return ''; }     }      public void Serialize()     {     }      public void Unserialize()     {     } } 

After that, you need to regasm your assembly. Regasm will add the necessary registry entries to allow your .NET component to be see as a COM Component. After, you can call your .NET Component in C++ in the same way as any other COM component.
