How to get the lines of code that are not covered to be highlighted by dotCover in VisualStudio?

Question

When I run Extensions→ReSharper→Unit Tests→Cover All Tests from Solution, I get a coverage tree. But when I double-click a branch, I do not see any highlights that indicate which lines of code were not covered.  It only takes me to the method indicated on the coverage tree.

The same happens if I use Rider →Cover all Unit tests.

How to get the lines of code that are not covered to be highlighted?

Answer

dotCover highlighting needs to be enabled

VisualStudio: Tools | Environment | Fonts and Colors | DotCover Code Marker

Rider: Settings | Build, Execution, Deployment | dotCover | Highlighting or a button on the toolbar of the Unit Test Coverage tool window
