Code Inspection: Use explicit or implicit modifier definition for types

C# modifiers of types and type members can be written in any order. However, arranging them in a similar way throughout your code is a good practice, which improves code readability. Besides, you may prefer using or not using private and internal modifiers explicitly.

By default, JetBrains Rider suggests to use private and internal modifiers explicitly, and to arrange modifiers in a specific order. If necessary, you can flexibly configure these preferences.

For more information about configuring and enforcing your preferences for type and member modifiers, see Code Syntax Style: Modifiers.
