What is the way of loading data in Entity Framework?
Entity Framework supports three ways to load related data – eager loading, lazy loading and explicit loading.
How load all entities in Entity Framework?
In Eager Loading, all relevant data for an entity is loaded at the time of the query of the entity in the context object. Eager Loading can be done by using the “Include” method. To perform Eager Loading, Lazy Loading must be disabled.
How do I load related entities in Entity Framework Core?
Entity Framework Core allows you to use the navigation properties in your model to load related entities. There are three common O/RM patterns used to load related data. Eager loading means that the related data is loaded from the database as part of the initial query.
What is collection method in Entity Framework?
The Collection() method gets an object that represents the collection navigation property. The Load() method executes the SQL query in the database to get the data and fill up the specified reference or collection property in the memory, as shown below.
What is difference between lazy loading and eager loading?
Lazy Loading vs. Eager Loading. While lazy loading delays the initialization of a resource, eager loading initializes or loads a resource as soon as the code is executed.
How to load related data in Entity Framework?
Thank you. Entity Framework supports three ways to load related data – eager loading, lazy loading and explicit loading. The techniques shown in this topic apply equally to models created with Code First and the EF Designer.
What is eager loading in Entity Framework?
The techniques shown in this topic apply equally to models created with Code First and the EF Designer. Eager loading is the process whereby a query for one type of entity also loads related entities as part of the query. Eager loading is achieved by use of the Include method.
What is the difference between collection and query in Entity Framework?
On the other hand, the Collection method should be used when an entity has a navigation property to a collection of other entities. The Query method provides access to the underlying query that Entity Framework will use when loading related entities.
How do I load related entities with lazy loading?
Loading of related entities can still be achieved using eager loading (see Eagerly Loading above) or the Load method (see Explicitly Loading below). Even with lazy loading disabled it is still possible to lazily load related entities, but it must be done with an explicit call. To do so you use the Load method on the related entity’s entry.
