Open Ria Services simplifies the development of n-tier solutions for Rich Internet Applications (RIA), such as Silverlight applications. A common problem when developing an n-tier RIA solution is coordinating application logic between the middle tier and the presentation tier. To create the best user experience, you want your Open Ria Services client to be aware of the application logic that resides on the server, but you do not want to develop and maintain the application logic on both the presentation tier and the middle tier. Open Ria Services solves this problem by providing framework components, tools, and services that make the application logic on the server available to the Open Ria Services client without requiring you to manually duplicate that programming logic. You can create a Open Ria Services client that is aware of business rules and know that the client is automatically updated with latest middle tier logic every time that the solution is re-compiled.
