I'd try using tcom for this.  Create a C# class library that
implements the  interface that you want, here is my sample one:

 using System;
 namespace ClassLibrary1
 {
    public class Class1
    {
    public Class1()   {}
    public int Double (int val)  { return val * 2 ;  }
    }

 }

Make sure that the project has register for COM Interop set to true
and then build it.  You should now be able to do the following:

 C:\Projects\ClassLibrary1\bin\Debug>tclsh
 % package require tcom
 3.9
 % set myCom [tcom::ref createobject "ClassLibrary1.Class1"]
 ::tcom::handle0x00923F98
 % $myCom Double 6
 12
 %

Hope this helps
