ReSharper cannot resolve symbol

Question

I'm currently building an ASP.NET 5 (ASP.NET Core 1.0) MVC application. I'm using Visual Studio 2015 with ReSharper Ultimate 10.0.2.

I currently have a 2-tier layer solution which consists of a Www (web application) and a Services layer. The Www has a reference to the Services layer.

When ReSharper is suspended, the classes within the Www layer are able to invoke objects from the Services layer, as shown here:

However, when ReSharper is enabled, I get the following message: Cannot resolve symbol 'Services', as shown here:

What I've tried:

1. Clearing the caches from Tools -> Options -> ReSharper Ultimate -> Options -> Clear Caches
2. Remove the JetBrains folder from %APPDATA%
3. Restarting Visual Studio 2015
4. Reinstalling ReSharper
5. Suspending and resuming ReSharper
6. Adding and removing references
7. Rebuilding the solution

Any help is appreciated.

Answer 1

In Visual Studio 2017 I solved in this way:

• Close the solution
• Delete the ".vs" hidden folder
• Reopen the solution and rebuild it
