Code Inspection: Use preferred style for trailing comma before new line in multiline lists

This code inspection checks that trailing commas in multi-line declarations with multiple items and simmilar constructs (object, array, and collection initializers, as well as enums and switch expressions) conform to your code style.
Depending on your preferences, it either detects redundnt trailing commas or missing trailing commas.

The prefereces are configured on the Editor | Code Style | C# | Syntax Style page of JetBrains Rider settings Ctrl+Alt+S, under Triling comma.
