Code inspection: Some values of the enum are not processed inside 'switch' expression and are handled via exception in default arm
tip
note
This inspection suggests that you use a C# 8.0 feature.
By default, ReSharper automatically detects C# version based on the associated compiler. However, you can specify the target C# version explicitly for a project — right-click the project in the Solution Explorer, choose Edit project item properties from the context menu and use the C# Language Level selector .
To set the C# version for all projects in your solution, specify it in a Directory.Build.props file in your solution directory as described here.
