Code inspection: Virtual (overridable) member is never overridden (private accessibility)

tip

You can suppress this inspection to ignore specific issues, change its severity level to make the issues less or more noticeable, or disable it altogether.

This inspection detects methods and properties with the virtual modifier in situations when the containing class has inheritors but the virtual members have no overrides in any of them. To improve code readability, JetBrains Rider suggests making such members non-virtual.
