Working with ServiceDesk Plus Data in LINQPad

The CData ADO.NET Provider for ServiceDesk Plus enables you to use standard ADO.NET interfaces like LINQ and the Entity Framework to work with ServiceDesk Plus 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.

   Using OAuth Authentication

   ServiceDeskPlus uses Zoho OAuth 2.0 for secure authentication. To set up OAuth access:

   1. Register your application in the Zoho Developer Console at https://api-console.zoho.com
   2. Configure your redirect URI to match your application setup
   3. Note your Client ID and Client Secret from the application settings

   After setting the following connection properties, you are ready to connect:

   • AuthScheme: Set this to OAuth.
   • OAuthClientId: Set this to your Zoho application Client ID.
   • OAuthClientSecret: Set this to your Zoho application Client Secret.
   • Scope: Set this to the required ServiceDeskPlus permissions (default includes read access to requests, problems, assets, and projects).
   • Domain: Set this to your ServiceDeskPlus domain
   • Portal: Set this to your ServiceDeskPlus portal

   Example Connection String

   Profile=C:\profiles\ServiceDeskPlus.apip;ProfileSettings="Portal=itdesk;Domain=.in;Scope=SDPOnDemand.requests.READ SDPOnDemand.problems.READ SDPOnDemand.assets.READ SDPOnDemand.projects.READ";AuthScheme=OAuth;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;
   

   Below is a typical connection string:

   Profile=C:\profiles\ServiceDeskPlus.apip;ProfileSettings="Portal=itdesk;Domain=.in;Scope=SDPOnDemand.requests.READ SDPOnDemand.problems.READ SDPOnDemand.assets.READ SDPOnDemand.projects.READ";AuthScheme=OAuth;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;

   

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 ServiceDesk Plus connection in LINQPad.

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