Code Inspection: Use preferred style of default value expression when type is not evident

When you evaluate a default value of a type with the default value expression, and the type can be inferred, you can use either the default(T) operator or the default expression.

In other words, type specification (T) is optional with default when the type can be inferred.

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

By default, JetBrains Rider highlights type specifications as redundant and helps remove them:

If you prefer to have explicit type specifications in your code, you can change the corresponding preferences and JetBrains Rider will help you add missing type specifications:
