    Thanks for the quick walkthrough. My installation won't get past the svcutil step. It generates the error:

    Unhandled Exception: System.IO.FileLoadException: Could not load file or assembly 'svcutil, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. Strong name validation failed. (Exception from HRESULT: 0x8013141A)
    File name: 'svcutil, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' ---> System.Security.SecurityException: Strong name validation failed. (Exception from HRESULT: 0x8013141A)

    The issue I guess is with regards to svcutil.exe not being signed. To correct:

    At the Visual Studio 2008 command window prompt

    Get to the folder where svcutil.exe is (e.g C:\Program Files\Microsoft SDKs\Windows\v6.0a\bin\)

    Issue the command: sn -Vr svcutil.exe
