There’s just a little more work needed defining the model types, and doing some configuration. If the issues don’t apply to your scenario, go ahead and use lazy loading. Using lazy loading, every time a property is accessed and the data is not yet retrieved, a query to the database is done.īecause of the disadvantages of lazy loading, comparing the implementations of lazy loading between Entity Framework and EF Core, it’s now implemented in a different way. Using explicit loading, usually the same number of queries like with lazy loading are done – it’s just shown explicitly where the database access is used. Using eager loading you can reduce the number of queries, and access relations with a single SQL query. More queries than needed could be done to retrieve data from the database. With lazy loading, reading the code you can easily miss where queries to the database are done. I usually prefer eager loading or explicit loading to lazy loading. This article gives information on lazy loading which is very different to lazy loading with Entity Framework 6. With EF Core, lazy loading is available since version 2.1. ![]() Instead, just accessing the property dynamically invokes a query to the database to retrieve the data for the needed references. With lazy loading, you do not need to explicitly invoke the Load method. ![]() With explicit loading you explicitly invoke the Load method when references to single items or collections should be loaded. This is best when knowing in advance the needed references. ![]() Specifying the query, you use the Include method to define what references should be included. With eager loading you load references by specifying what references should be included when defining the query. Using EF Core, references can be eager loaded, explicitly loaded, and lazy loaded.
