Working with Dynamics CRM Data in LINQPad



Execute LINQ queries to Dynamics CRM data in LINQPad.

The CData ADO.NET Provider for Dynamics CRM enables you to use standard ADO.NET interfaces like LINQ and the Entity Framework to work with Dynamics CRM data. This article will demonstrate the process of establishing a connection from LINQPad and executing LINQ queries.

Create the Data Model

After downloading and installing both the provider and LINQPad, create a new class library project within 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.

    The connection string options meet the authentication and connection requirements of different Dynamics CRM instances. To connect to your instance, set the User and Password properties, under the Authentication section, to valid Dynamics CRM user credentials and set the Url to a valid Dynamics CRM server organization root. Additionally, set the CRMVersion property to 'CRM2011+' or 'CRMOnline'. IFD configurations are supported as well; set InternetFacingDeployment to true.

    Additionally, you can provide the security token service (STS) or AD FS endpoint in the STSURL property. This value can be retrieved with the GetSTSUrl stored procedure. Office 365 users can connect to the default STS URL by simply setting CRMVersion.

    Below is a typical connection string:

    User=myuseraccount;Password=mypassword;URL=https://myOrg.crm.dynamics.com/;CRM Version=CRM Online;
  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 Dynamics CRM connection in LINQPad.

Connect to Dynamics CRM 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 Dynamics CRM data through LINQPad. For examples of the supported LINQ queries, see the "LINQ and Entity Framework" chapter in the help documentation.
