Azure Analysis Services ADO.NET Provider

Rapidly create and deploy powerful .NET applications that integrate with Azure Analysis Services.



Execute LINQ queries to Azure Analysis Services data in LINQPad.

The CData ADO.NET Provider for Azure Analysis Services enables you to use standard ADO.NET interfaces like LINQ and the Entity Framework to work with Azure Analysis Services data. This article shows how to connect from LINQPad and execute LINQ queries.

Create the Data Model

After downloading and installing the provider and LINQPad, create a new class library project in Visual Studio.

See the help documentation for a guide to setting up an EF 6 project to use the provider.

  1. Right-click your project and click Add -> New Item -> ADO.NET Entity Data Model. In the resulting dialog, select Code First from database. Click New Connection and specify the connection string options in the resulting wizard.

    To connect to Azure Analysis Services, set the Url property to a valid server, for instance, asazure://southcentralus.asazure.windows.net/server, in addition to authenticating. Optionally, set Database to distinguish which Azure database on the server to connect to.

    Azure Analysis Services uses the OAuth authentication standard. OAuth requires the authenticating user to interact with Azure Analysis Services using the browser. You can connect without setting any connection properties for your user credentials. See the Help documentation for more information.

    Below is a typical connection string:

    URL=asazure://REGION.asazure.windows.net/server;
  2. Select the desired tables and views and click Finish to create the data model.

  3. Build the project. The generated files can be used to create the Azure Analysis Services connection in LINQPad.

Connect to Azure Analysis Services Data in LINQPad

After you have obtained the required connection properties and created the data model assembly, follow the steps below to start using the data model in LINQPad.

  1. Open LINQPad and click Add Connection.

  2. Select the "Use a typed data context from your own assembly" option.

  3. Select Entity Framework DbContext.

  4. Click Browse next to the Path to Custom Assembly box and browse to your project folder. Browse to the .dll or .exe under the bin folder.

  5. Select the name of the DbContext.
  6. If you saved your connection string in App.Config, specify the path to the App.config.

You can now query Azure Analysis Services data through LINQPad. For examples of the supported LINQ queries, see the "LINQ and Entity Framework" chapter in the help documentation.
