I wanted to define my default build quality at one of my Team Build Types in TFS 2008 like I did at Team Build 2005. But… 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 you set the build quality? Use the SetBuildProperties task. Read about it here;
