Sonar-dotnet: S3928 FP nameof(this.*)

[Khaos66]

Description

I observed a false positive for rule 3928.

Repro steps

Consider the following property:

   private string input;
   public string Request
   {
      get => this.input;
      set => this.input = value ?? throw new ArgumentNullException(nameof(this.Request));
   }

Expected behavior

No warning

Actual behavior

S3928 violation is reported by Sonar

thanks @Khaos66 . It will work if you pass nameof(value) - the actual parameter name is value, not Request. And I guess this is what a receiver of ArgumentException would expect, right?

I also wonder, why do you think this is right behaviour?

[Khaos66]

Yes. My bad!
