C# How to return null or an model

Question

I have Store Model that I want to return null if my model is null.

public Store Details() => db.Store.Single(s => s.Id == 1);

This query sometimes return a value and sometimes returns null. How can I specific the return type to include both?

Try to use

public Store Details() => db.Store.FirstOrDefault(s => s.Id == 1);
