Can ReSharper 7.x be configured to work with Visual Studio 2013 preview?
The preview version doesn't appear to allow it by default - though I only tested by repairing ReSharper, rather than uninstalling/reinstalling.
I'm aware that ReSharper 8 is on its way and may be a better long term option.
Being able to evaluate a new IDE under the same conditions that I use VS2012 is imperative, so this would help massively in that goal.
UPDATE
It looks like the answer to this is that it cannot be used - the accepted answer demonstrates a possible, untested method of wiring it up but there are now 3 or 4 cases where the solution has not worked, including an attempt by myself to hook it up which unfortunately didn't work. As such, I've added this update to avoid misleading anybody who comes across this.
