Is Team Build 2012 compatible with Team Foundation Server 2010?

Question

What is the experience connecting Team Build 2012 to a Team Foundation Server 2010?

We need to create a couple of more build agents, but Team Foundation Server will not be upgraded until a later time.

Confirmed: this will not work. You must upgrade TFS 2010 to 2012. I received an error attempting to install a 2012 build service against TFS 2010:

"The register command is not supported for Team Foundation Server [my server] because the server is not compatible."

After upgrading TFS 2010 to 2012 it installed fine. Note that upgrading TFS 2010 to 2012 means backing up your database, uninstalling 2010, installing 2012, and then choosing "Upgrade" from the Configuration Center.
