Repro steps:
1) Have a class that has a string property in it (i.e. public class Foo { public string Bar { get; set; } }).
2) Create a method that has that class as a parameter (i.e. public void FooBar(Foo x)).
3) Use the null conditional operator to check whether 'Bar' is null (i.e. if (string.IsNullOrWhiteSpace(x?.Bar)).
4) Try and use the 'x' parameter (i.e. var z = x.Email;)
5) Get a 'Possible null exception alarm', even though the check would fail.
