Building VS 2008 projects with TFS 2005
When you try to build VS 2008 solutions with Team Foundation Build 2005 you get:
MSB5014 - File format version is not recognized.
I posted about it and one of the comments (by Eran Kampf) linked to Mitch Denny's approach. Customers ask me about it a lot and this is the best approach to deal with the problem
Buck Hodges said that the best "workaround" is to upgrade to TFS 2008. But not all of you will upgrade soon to 2008. Until then, use Mitch's approach.
