Code Inspection: Non-accessed field (Private accessibility)

C# compiler can issue a number of warnings regarding unused fields:

• CS0649: Field is never assigned to, and will always have its default value

• CS0169: Private field is never used

• CS0414: Private field is assigned a constant value but never used

Although JetBrains Rider knows about all these warnings and provides design-time notifications for them, it goes one step further and detects unused fields not covered by compiler warnings. The example below shows that even if a field is assigned non-constant value and has no read usages, JetBrains Rider will help you detect the unused member.
