How to include nullable objects and then ThenInclude another nullable object in EF Core?

Question

I am using jet brains Rider and Resharper gives an error when i dont declare objects like Organization as nullable.

Actually, it should be nullable, since i might not include it in the EFCore query.

Now I've set it to public Organization? Organization { get; set; }

The problem I'm facing is this:

What is the best way to solve this warning? What is the best practice here?

Post your code as text. The warning doesn't appear in the Include operations. The actual code is hidden by a popup — Panagiotis Kanavos

@JohnathanBarclay maybe not - these aren't DbSets and the actual warning is raised in the Where operator which is hidden by a popup. For all we know this may be a valid warning — Panagiotis Kanavos

All the more reason to post both code and warnings as text, not images — Panagiotis Kanavos

The warning is safe to ignore since the expression will be translated by EF core to an SQL Query, and won't be actually evaluated by the .NET runtime (so no NullReferenceException would be thrown).

So the ! (null-forgiving) operator can be used to silence the warning as in

Where(g => g.Organization!. /* rest of the expression here*/ )
