After upgrade to v16.2.3 navigation feature JumpToSymbol is broken when being configured as shown in the attached screenshot. It doesn't find classes or interfaces anymore when members are deactivated. After activating ALL member options it works again.
This has been working in the previous versions. I already tried to reset all CCR settings, no luck.
I managed to revert to an older version. Just an FYI for others who need to revert back until the bug is fixed.
Uninstall CodeRush for Roslyn.
Download the previous version from Download Your Products
Install the vsix
Open Visual Studio and click on "Tools" > "Extensions and Updates...".
Locate CodeRush for Roslyn and uncheck "Automatically update this extension".
