How can I find the implementation/source code of an interface in .NET?

Question

So I'm disassembling the Winnov.Amalga.Core.Session.Common.dll, and trying to figure out how the WriteScriptCommand works.

I'm absolutely new to .NET, so go easy on me, please. You can find the dll yourself here: Link under the Binary folder.

Below is pretty much the only reference I found. EDIT: From searching through the decompiled dll.

using System;
namespace winnov.Amalga.core
{
  public interface ISession
  {
     string Configuration { get; set; }
     SessionState { get; }
     TimeSpan Duration { get; }
     string ArchiveBasePath { get; set; }
     string ArchivePath { get; }
     void Start();
     void Stop();
     void ApplyPreset(string presetxml);
     void writeScriptCommand(string name, string value);
   }
}

Answer 1

If you look at the decompiled code for the Winnov.Amalga.Core.Client constructor, you'll see that this._Session is a web service interface to whatever web service was used when constructing Winnov.Amalga.Core.Client. Thus, Session.WriteScriptCommand() is a server-side function and its code is not in Winnov.Amalga.Core.Session.Common.dll.
