Using LINQPad with Entity Framework

LINQPad lets you query Entity Framework models that you define in Visual Studio. Here's how to proceed:

  1. Create an ADO.NET Entity Data Model in a Visual Studio project, and build.
  2. From LINQPad, click Add Connection (top left) and choose Entity Framework in the bottom listbox. If you're using Entity Framework 4.1/4.2 code-first, choose Entity Framework - POCO).
  3. Click Browse and locate the assembly (DLL or EXE) that you built in step 1:
    Entity Framework Choose Assembly
  4. Choose your typed ObjectContext class and Entity Data Model: Entity Framework Choose EDM
  5. Confirm the SQL Server and database details and click OK.

    Your Conceptual Model will now show in the Schema Explorer. Right-click to start a new query:
