AsNoTracking() and Include

Question

I have a Linq query that fetches an entity and some of its navigation properties.

context.MyEntity
    .AsNoTracking()
    .Include(i=> i.Nav1)
    .Inclu         


        

Answer 1

Use AsNoTracking after you have completed all your query parameters but before you move the data into memory. In this example, you'll want:

context.MyEntity
    .Include(i=> i.Nav1)
    .Include(i=> i.Nav2)
    .Where(x=> x.Prop1==1)
    .AsNoTracking()
    .FirstOrDefault();

Any child objects of the parent entity will not be tracked.
