LINQ provides general-purpose query facilities in .NET Framework 3.0 and above and provides one easy way to programmatically access data through from CData ADO.NET Data Providers. This example uses LINQ to access information from the LinkedIn Data Provider.

This article demonstrates how to use LINQ to access LinkedIn tables through the CData ADO.NET Data Provider for LinkedIn. To do this you will LINQ to Entity Framework, which is used to generate the connection and can be used with any CData ADO.NET Data Providers to access data via LINQ.

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

  1. In a new project in Visual Studio, right-click on the project and choose to add a new item. Add an ADO.NET Entity Data Model.
  2. Choose EF Designer from Database and click Next.
  3. Add a new Data Connection, and change your data source type to "CData LinkedIn Data Source".

  4. Enter your data source connection information.

    LinkedIn uses the OAuth 2 authentication standard. You will need to obtain the OAuthClientId and OAuthClientSecret by registering an app with LinkedIn. For more information refer to our authentication guide.

    Below is a typical connection string:

    OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:portNumber;CompanyId=XXXXXXXInitiateOAuth=GETANDREFRESH
  5. If saving your entity connection to App.Config, set an entity name. In this example we are setting LinkedInEntities as our entity connection in App.Config.
  6. Enter a model name and select any tables or views you would like to include in the model.

Using the entity you created, you can now perform select , update, delete, and insert commands. For example:

LinkedInEntities context = new LinkedInEntities(); var companystatusupdatesQuery = from companystatusupdates in context.CompanyStatusUpdates select companystatusupdates; foreach (var result in companystatusupdatesQuery) { Console.WriteLine("{0} {1} ", result.Id, result.VisibilityCode); }

See "LINQ and Entity Framework" chapter in the help documentation for example queries of the supported LINQ.
