TFS 2010 exposes a "Build Number Format" property, which contains $(BuildNumberDefinitionName) and $(Rev:.r) variables (among other things). Two and a half parts to my question:
What are all the available variables that can be used here?
Where does the value for $(Rev:.r) come from (where is it stored)?
a. Can it be reset or changed?

Anytime you change your Build Number in a TFS build, the revision resets to 1, which is what it should do, most of the time. But sometimes, you want to start at revision 100, maybe recreating a deleted build definition, or just wanting to maintain the old revision into a new branch. It took me a lucky accident to discover how this is possible. You must replace the dynamic revision with a hard coded one, build, and then change it back. Out of frustration I eventually tried this:
Build Number Format: 1.0.0.100
This gave me the build I wanted, and then changed it back to this:
Build Number Format: 1.0.0$(Rev:.r)
This picked up my last value, starting future build at 1.0.0.101, instead of incrementing the last version that it had used, 1.0.0.2. So I was able to skip builds 1 through 99 and start at revision 100 in my build number.
