What is Entity Framework fluent api?

Question

I keep hearing about the Entity Framework fluent-api but I am struggling to find a good reference on this. What is it?

We use the entity framework and the modeling tool

Answer 1

See the paragraph on POCO classes in http://www.asp.net/entity-framework/tutorials/creating-an-entity-framework-data-model-for-an-asp-net-mvc-application

Essentially, in the context of EF, POCO classes are entity classes that do not inherit from the Entity Framework EntityObject class (which is what you get by default in Database First or Model First). As one of the other answers mentions, this makes it easier to serialize the objects, but also some development and automated testing methodologies prefer to work with objects that have no reference to the Entity Framework.
