I know that there are problems in VS 2010 between the Productivity Power Tools and R#. I just activate features of the power tools which do not conflict with R# and therefore i personally don't have problems. So it's annoying that i can't continue the installation of an EAP build without deinstalling the power tools. Is this really necessary? It would be fine, if possible, to make the automatic deinstallation of the Productivity Power Tools optional.
