This topic describes how to add or remove a Open Ria Services link between a new Silverlight client application and an existing ASP.NET project.

A Open Ria Services solution basically consists of client and a server projects that are linked by such a Open Ria Services link, so adding and removing them is a critical task.

This topic assumes that you have completed the [Walkthrough: Creating a Open Ria Services Solution](https://openriaservices.gitbook.io/openriaservices/ee707336/ee707376), [Walkthrough: Using the Silverlight Business Application Template](https://openriaservices.gitbook.io/openriaservices/ee707336/ee707360), and [Walkthrough: Creating a Open Ria Services Class Library](https://openriaservices.gitbook.io/openriaservices/ee707336/broken-reference) topics, or have equivalent knowledge and an existing Open Ria Services solution available.

When you create a new Silverlight Business Application project, you can create a new Open Ria Services Class Library project, or you can select the **Enable Open Ria Services** check box in the **New Silverlight Application** dialog box, and a Open Ria Services link between the client project and the server project is created automatically.

### To add a Open Ria Services link to an existing solution

1. Open an existing Open Ria Services solution.
2. In **Solution Explorer**, right-click the Silverlight client project and select **Properties**.

   The **Silverlight** tab of the project designer appears.
3. In the **Open Ria Services link** drop-down list, select the server project that you want to use for the middle tier with this client project.
