Note that SFTComServer is the name of your COM server component.

There are couple of steps before you use the COM DLL into your C# application:

1.   Create a strong name file as shown below:
      C:\kathir\SFTComServer>sn -k key.snk

2.   Create the DLL that is compatible with C# using tlbimp
      C:\kathir\SFTComServer>tlbimp release\SFTComServer.tlb /keyf
      ile:key.snk /out:SFTComServer_vsnet.dll /namespace:SFTCOMServer

      Microsoft (R) .NET Framework Type Library to Assembly Converter          2.0.50727.42
      Copyright (C) Microsoft Corporation.  All rights reserved.

      Type library imported to C:\kathir\SFTComServer\SFTComServer

3.   Register the newly created .DLL

      C:\kathir\SFTComServer>regasm SFTComServer_vsnet.dll
      Microsoft (R) .NET Framework Assembly Registration Utility             2.0.50727.3053
      Copyright (C) Microsoft Corporation 1998-2004.  All rights reserved.

      Types registered successfully

4.   Register the COM DLL if you have not done so far.

Now is the time to write C# test application by adding a reference to the newly created SFTComServer_vsnet.dll.
