Specifies whether the Link<T> has loaded or assigned a value.
Assembly: System.Data.Linq (in System.Data.Linq.dll)
"Loaded" means that the data was loaded during materialization or at deferred loading. "Assigned" means that you have manually given the data a value.
LINQ to SQL uses this property to make sure that the Link<T> has a value, so that accessing it will not trigger deferred loading.
