Explain lazy loading in entity framework?

Lazy Loading is a process of collection of entities or a single entity that is loaded spontaneously for the first time from the database and property that refers to those entities or entities can be accessed. In other words, lazy loading means delaying the loading of related data, until it is specifically requested. While loading the POCO type of entities, lazy loading is produced by generating derived proxy type instances. Lazy loading then overrides the virtual properties to insert the hook of the loading.

If the configuration is defined as the default and proper instruction is not given to the entity framework in a query, then it will return the lazy loading only.
