QueryableExtensions.AsNoTracking Method (IQueryable)

[This page is specific to the Entity Framework version 6. The latest version is available as the 'Entity Framework' NuGet package. For more information about Entity Framework, see msdn.com/data/ef.]

Returns a new query where the entities returned will not be cached in the DbContext or ObjectContext. This method works by calling the AsNoTracking method of the underlying query object. If the underlying query object does not have an AsNoTracking method, then calling this method will have no affect.

Namespace:  System.Data.Entity
Assembly:  EntityFramework (in EntityFramework.dll)
