I just updated from Resharper 10.1 to Resharper 10.2, and now I am always seeing the "Delegate invocation can be simplified" tip on delgate invocations, which is to change "if (OnWhatever != null) OnWhatever()" into "OnWhatever?.Invoke()". The problem is I'm using C# 4 and that should only be showing up for C# 6. Resharper 10.1 correctly didn't show the tip when I had "C# 4" selected as my C# level in a project, but Resharper 10.2 does. Also, if I click the light bulb to try to make the change it will often throw a Resharper error and ask if I want to disable that tip but disabling it doesn't stop it either. I also can't find a setting anywhere in Code Inspection to turn it off. Any ideas?
