A couple of weeks ago a project I participated in went live on Codeplex.
I had the chance to get a nice close look at the internals of TFS process templates with this project and I am really satisfied with the result.
TFS process templates are quite powerful and flexible, probably the strongest selling point for TFS (not being a process expert I like what I see – but then being a build&test expert I find a lot to wish for in TFSBuild).
The project is a small set of tools for adapting the V-Model XT process for the TFS environment.
V1.0.0 is 100% code from yours truly.
