For example, let's start creating classes for our school domain, the Employee class has the “EmployeeID” property so it will create EmployeeID as the PK column. The column names and datatype matches with the properties of the respective domain classes. Code First for the Entity Framework. It creates the database based on a parameter passed in the base constructor of your context class. In a Model-First scenario, a developer first creates an Entity Framework object-relational data model. The stored procedure will modify the database data and return the results with an implicit resultset. Instead of designing database tables first, as and when needed. The code executes a LINQ query against the EDM you just created.
