"Auto-property accessor is never used" warning from ReSharper

Question

Our Application is an MVC Application . I tried to run code analysis using ReSharper. I am getting "Auto-property accessor is never used" as warnings in many of my view model properties.

For example, ReSharper shows the warning on this:

public bool IsLegalEntry { get; set; }

Can I make a private setter, or can anybody suggest an alternative?

@Андрей that will hide the warning but break the application. MVC's models need publicly-writable properties. Making the setter private is not the solution here. — CodeCaster, Jun 09 '17 at 12:27

Yeah thanks for the reply. So thats the confusion. If we tried to solve the warning it may affect the application. — Sri vahgar, Jun 09 '17 at 12:30

You could make the setter private

public bool IsLegalEntry { get; private set; }

However, this could cause a runtime error if the setter is used implicitly. Alternatively you could decorate the setter with the JetBrains.Annotations.UsedImplicitlyAttribute.

public bool IsLegalEntry { get; [UsedImplicitly] set; }

Alternative to "warning fixing/suppressing" paradigm, you can add testing project to your solution. Then write a test for you business logic hitting the accessor(s) in question among other things.

Not sure this is the action you were looking for, however

it provides the effect you were after
saves for redundant annotation attributes
adds testing bonus

Be careful not to add tests that don't add value just to suppress a warning. Testing that calling get on a auto property after calling set for the same auto property is pretty useless and just adds cruft to your project. – Steven Benitez Feb 17 '23 at 19:05
