A client was asking me this today so I decided to make a quick note and send a link :)
In TFS 2010 when trying to make Sequential builds (i.e. for one you have several interdependent solutions in your automation strategy) in the DefaultTemplate XAML file you have to change the
. It should be noted that this is a lot different than TFS 2008. In TFS 2008, in the TFSBuild.proj file the solutions were just ordered correctly and made use of the BuildSolutionsInParallel property. This also required changing the setting for the MaxProcesses in the tfsbuildservice.exe.config file on the build server to a value greater 1, and also to restarting the build service on the build server. This is a lot more cumbersome than changing the type tag mentioned above.
