Warning: This has only been tried by me just now on VS2013 with the latest v8 EAP, this may cause crashes or slowdowns etc and I can’t say how v7 would behave.
If you go into your program files folder, then open the VS2012 folder, navigate to Microsoft Visual Studio 11.0\Common7\IDE\Extensions .
From that folder grab the Jetbrains folder, and copy and paste it to the same location but substitute 11.0 for 12.0.
Then open the file inside the Jetbrains folder named extension.vsixmanifest in any text editor of choice (remember about running as admin) then inside find where at the top on approx lines 11 – 16 , you will have a section named VisualStudio.
Copy and paste this whole block and paste it again below (inside the SupportedProducts section still).
Edit the Version=”11.0″ to Version=”12.0″ and then save the file, re-launch VS2013 & you should now end up with resharper working.
Nice and simple 🙂 Also for future reference this technique works on any extension, also some extensions are stored in AppData instead. Just thought I’d reply with this to make sure you got a helpful reply 😀
