In the Solution Explorer window, select and click Model Browser.

Type in the highlighted code below or copy the code from the from the section labeled "LINQ using lambda expressions --" and paste it in after the previous code statements.

This section will demonstrate three common EDM querying methods: LINQ, LINQ with lambda expressions, and Entity SQL.

Model-First allows the conceptual model to be created first by the developer.

NET data querying language which can query a multitude of data sources, one of which are entities via LINQ to Entities.

Note: Press Enter to continue after viewing the first resultset.

In this section, you will query the same rows as in the previous section to show that the stored procedure successfully updated the selected rows.

You will then create the code to execute a LINQ query and return the results to the console window. The code executes a LINQ query against the EDM you just created.

Type the namespace references highlighted in the graphic below. It then accesses the result and outputs it to the screen.Before starting this tutorial, you should: In the Server Explorer window, if you already have a HR schema connection, expand it to connect to the database. Open the working directory to where you extracted the As an example, the screen shot below identifies the HR schema as HR. Enter HR for the User name and a password and click OK. If you do not have a HR connection, then right-click on Data Connections in Server Explorer. Select Default as the Role and click Test Connection. Find the INCREASE_SALARY_BY_10, UPDATE_AND_RETURN_SALARY and OUTPARAM stored procedures.Entity SQL Next, you will call a stored procedure added to the EDM via a function import.The stored procedure will modify the database data and return the results with an implicit resultset.In a Model-First scenario, a developer first creates an Entity Framework object-relational data model.
