Get a specific version of a file
You can use Blend para Visual Studio 2012 to get earlier versions of a file. This is useful if you want to view an earlier version of a .xaml file on the artboard in Blend.
Alternatively, you can view or compare versions of a file in a text viewer. For more information, see View or compare the changes made to files.
If you want to revert the checked-in file on the Team Foundation server to an older version, use the procedure at How to: Roll Back a Changeset on MSDN.
Get a specific version of a file from source control
You can use the following procedure to get a version of a file based on its changeset number (the number that identifies the set of changes that was checked in). For alternative procedures, see How to: Get the Source for Your Team Project on MSDN.
[!NOTA]
This procedure gets every version-controlled item in the changeset so that you end up with a complete set of files that will build without errors. If you were to retrieve only one file from a changeset, you might be missing changes in other files that allow the solution to build.
