ReSharper configuration in VS solution

You can uncheck the ones that you don't want to use from Live Templates window. foreach template is under iterations group.

Try installing a later build of ReSharper from the Nightly Builds site. I recently installed build 1277, and it's very stable and great.

Also, try deleting the ReSharper cache from the root of your solution (folder starting with _ReSharper.*), and if you have any 3^rd party plugins, such as Agent Smith, try disabling them (in ReSharper → Plugins).
