I wanted to define my default build quality at one of my Team Build Types in TFS 2008. In Team Build 2005 we could define the default build quality. However, in Team Build 2008, the default build quality notion was removed.
Note: The default value for the build quality of a new build in TFS 2008 is null, not empty string.
So, how can we set the build quality? Use the SetBuildProperties task. Read about it here;
