For the benefit of those of you experimenting with Visual Studio 2008, particularly building Workflow Services. Visual Studio Beta2 (v9.0.20706.1) has a small flaw involving strong name validation.

So if you try to debug say a Sequential Workflow Service Library you may (will?) get an error indicating a System.IO.FileLoadException involving svcutil.

To solve this problem you need to do the following

1. Open Visual studio 2008 Beta 2 Command Prompt as Administrator

2. Go to C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin\

3. Execute this command: sn.exe -Vr svcutil.exe

Note: Also make sure to run as a Administrator.

We will be covering Workflow Services this coming Wednesday, so if you are interested in exploring this new powerful feature within Visual Studio 2008, please register here
