Create a new Rule to validate nullable reference types,null forgiving and unnecerssary ?. , ! and!

SonarLint

Imagine this class

public class Base
{
     public Child Child {get;set;} = new Child();
}
public class Child
{
     public string Description {get;set;} = string.Empty;
}

and in my code I have


var x = new Base();

var d = x.Child?.Description;

How can I show a message that this ?. is not necessary because it can’t be null?

Hey @luizfbicalho

Thanks for the suggestion, it’s a very good one.
I made an issue about this on sonar-dotnet, which you can find here

It will be considered and taken care of during an upcoming sprint about similar, null-tracking rules.

Regards,
Greg
