Multiple Includes() in EF Core

Question

I have an extension method that lets you generically include data in EF:

public static IQueryable IncludeMultiple(this IQueryable          


        

Answer 1

You can do something like this:

public Patient GetById(int id, Func, IIncludableQueryable> includes = null)
        {
            IQueryable queryable = context.Patients;

            if (includes != null)
            {
                queryable = includes(queryable);
            }

            return  queryable.FirstOrDefault(x => x.PatientId == id);
        }

var patient = GetById(1, includes: source => source.Include(x => x.Relationship1).ThenInclude(x => x.Relationship2));
