Can anyone offer advice on the best tool to use for integration between QC and TFS? Besides HP's add-in I've found information on a couple of third-party tools. Need something that is easy to get up and running. We've been using QC for several years and would like to continue to use it but want defects to sync between the two systems. We're on QC v10.0 now but will be upgrading to 11.0 soon. We just recently started using TFS 2010.
