![]() ![]() It loads the related data in scalar and navigation properties along with query results at the beginning. More here.Įager Loading is the opposite of Lazy Loading. The Load method cannot be used with POCO entities because the navigation properties of POCO entities are not required to return Entit圜ollection. Use Lazy Loading when you only need the main entity data to be fetched and you know that the related data will not be required.Įxplicit Loading is similar to Lazy Loading but it uses the Load method on an Entit圜ollection to explicitly load all contact numbers for a single friend. In other words, fetch all of them at once along with the main entity using Eager Loading. Use Eager Loading when the data in related entities is too costly to be loaded at the cost of the queries being made to the database. Eager Loading or Defining Query Paths with Include.NET 4.0 and Entity Framework we have various ways by which we can load data objects, some of them are listed below: These navigation properties return either a reference on the "one" end of a one-to-one or many-to-one relationship or a collection on the "many" end of a one-to-many or many-to-many relationship. When entities are generated based on the data model, navigation properties are generated for entities at both ends of an association, read here about navigation properties. As you know, entity types can define navigation properties that represent associations in the data model and you can use these properties to load entities that are related to the returned entity by the defined association. ![]() With Entity Framework we have various patterns that you can use to load related entities. ![]() In this article, you will learn what Eager Loading and Lazy Loading are and how they work in an application and how you can take advantage of them. ![]()
