Question

I am not able to access both the Source control in Visual Studio 2010 as in 2012 when I try to access this error is shown: "TF14045: The identity is not a Recognized identity". This error started after I detach the project collection from TFS 2010 and attach on Team Foundation Server 2012, anyone knows how to fix this?

Answer 1

I guess you have TFS 2012 with Update 1 installed? If so you have to wait for the upcomming patch that will contain a bugfix for this error. Have a look at Microsoft Social:

Answer 2

Never had this error, because the migration is planned for January, but I found this entry with some suggestions and answers from MS:

Answer 3

Just be sure that you have not opened two instances of Visual Studio & trying to connect two TFS servers which needs two different credentials/ domain.

I was facing that issue & after closing one of the instances, it started working fine.
