We have had a few requests from developers wanting to use the PureCM extension in Visual Studio 2012 RC.
If you want to try it out you can download it here:
PureCM.VSSourceControl2012.zip (9.22 mb)
Currently this extension is a beta and will remain so until the 2012-2 release in October (which should roughly coincide with the VS 2012 release). If you experience any problems please email support@purecm.com.
