Code Inspection: Use preferred style of 'new' expression when created type is not evident

Starting with C# 9.0, you can create objects with the target-typed new operator without explicit type specification when the type can be inferred, that is List<string> _myList = new(); instead of List<string> _myList = new List<string>();.

Depending on the context, the optional type specification can either clutter your code with redundant information or, on the contrary, improve the readability.

This inspection controls code style preferences for object creation expressions when the created type is not evident (for example, in return statements).

By default, JetBrains Rider suggests explicitly specifying the created type in non-evident cases:

If you prefer another style for the new operator in your code, you can change the corresponding preferences.
