I use: Visual Studio 2010 Ultimate, Resharer 6.
In ReSharper\'s options i choose Visual Studio keyboard sheme and click Apply Sheme:
This is a known issue that affects all ReSharper shortcuts that include F12 after switching from IntelliJ keymap to VS keymap. It's documented in this bug report that you're free to watch and vote for. As far as I'm aware, the only workaround would be to reassign the broken shortcuts manually through Tools > Options > Keyboard.
