Resharper 8 could not find implementations of interfaces

In some cases (Interface and implementation in different projects of the same solution) Ctrl + F12 (go to implementation) does not work. It says "Implementations of IYourService were not found". The same thing could happen when you want to implement some member. Clean + rebuild could help but not always.

It seems that Resharper 7 does not have such problem.

Have somebody met that issue? How to fix it?

Thanks in advance!

How do you open the implementation method in Visual Studio?

Choose Navigate | Go To Implementation in the main menu, press Ctrl+F12 , or click the symbol while holding Ctrl+Alt keys. Note that in Visual Studio 2017 and later, the Ctrl+Alt -click is used for adding multiple carets.

I tried clear the Resharper Cache: Resharper --> Options --> Environment --> General --> Clear Caches.

Then I close and reopen the solution to let the cache rebuild.

It works with Resharper 8.1 build.
