As you can see from the code, each TeamProjectCollection has its own store of Process Templates (in TFS 2008 there was in effect a single “Project Collection”) so we need to look through each collection to retrieve the templates that have been uploaded to it.

You’ll need references to Microsoft.TeamFoundation.dll, Microsoft.TeamFoundation.Client.dll, Microsoft.TeamFoundation.Common.dll.  On a machine with Visual Studio 2010 installed they should be found in C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\ReferenceAssemblies\v2.0 or C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\ReferenceAssemblies\v2.0 depending on whether you have a 64-bit version of Windows or not.  You’ll also need to set the Target Framework to .NET Framework 3.5 as the assemblies required are in the v2 GAC.

This code will work against TFS2010 Beta 2 but is not guaranteed to work in the RTM.
