EF Core Domain Projection

Question

Is there a performance difference between using a function inside a linq to sql select statement vs using an expression in EF core domain projection.

Ex.

context.Students.Select(x => StuddentDTOMapper(x)).ToList();

Vs.

context.Students.Select(StuddentDTOMapperExpression).ToList();

I don't think so. But you can always check it on your own. I can tell you that you can gain a little performance boost by compiling your expressions. You can read about it more here and here.
