Just now I received my new laptop from my office. When I open Visual studio, in the tools I am not able to see the Connect to Team Foundation Server option. Can any body help me out how to do that? in VS2008
You'll need to install the Team Explorer client (prior to 2010, it is a separate install). If you are connecting to TFS 2010 from VS2008, you'll also need the forward compatibility update.
You'll need to download and install these three things (in order) for a VS2008 client to connect to a TFS2010 server.
Team Explorer 2008 (if you don't already have it) from http://www.microsoft.com/downloads/en/details.aspx?FamilyID=0ed12659-3d41-4420-bbb0-a46e51bfca86. If you need a tool to mount an ISO file, MagicISO is a good one
Visual Studio 2008 Service Pack 1 from http://www.microsoft.com/downloads/en/details.aspx?FamilyId=FBEE1648-7106-44A7-9649-6D9F6D58056E.
Visual Studio Team System 2008 Service Pack 1 Forward Compatibility Update for Team Foundation Server 2010 from http://www.microsoft.com/downloads/en/details.aspx?FamilyID=cf13ea45-d17b-4edc-8e6c-6c5b208ec54d.
If the updates are not installed properly, you'll get this error when you try to connect:
TF253022: You must update your client with the Forward Compatibility Update in order to connect
