Gets or sets a value indicating whether the entity has been loaded from the database.
Assembly: EntityFramework (in EntityFramework.dll)
Loading the related entity from the database either using lazy-loading, as part of a query, or explicitly with one of the Load methods will set the IsLoaded flag to true. IsLoaded can be explicitly set to true to prevent the related entity from being lazy-loaded. Note that explict loading using one of the Load methods will load the related entity from the database regardless of whether or not IsLoaded is true. When a related entity is detached the IsLoaded flag is reset to false indicating that the related entity is no longer loaded.
