WCF RIA Services
Microsoft WCF RIA Services simplifies the traditional n-tier application pattern by bringing together the ASP.NET and Silverlight platforms using WCF. The RIA Services provides a prescriptive pattern to write application logic that runs on the mid-tier and controls access to data for queries, changes and custom operations. It also provides end-to-end support for common tasks such as data validation, authentication and roles by integrating with Silverlight components on the client and ASP.NET on the mid-tier. It includes rich tooling for integrating client and mid-tier projects and for building rich UI through the simplicity of drag-drop support.

Feature Samples
This sample demonstrates how RIA Service's developers can leverage the power and flexibility of the WCF platform. It demonstares how WCF behaviors can be added to a Domain Service, how an explicit .SVC file can be generated for the default Domain Service WCF endpoint and how a custom ServiceHost can be defined for a Domain Service.

WCF extensibility sample This sample demonstrates a WPF (Windows Presentaion Foundation) Application communicating with the WCF service exposed by a DomainService. The application does an AddServiceReference to the WCF DomainService to get a ServiceReferenceClient. It then queries the service for data, as well as makes updates to the data model.
The sample also shows has a Silverlight head working against the same Domain Service.

'Add Service Reference' to a Domain Service These quick starts cover the key use cases for the Authentication Service. While some show basic integration with ASP.NET, others tackle more complex scenarios including Custom Authentication, Out of Browser & Offline Autnentication, and Windows Live ID support. 'Quick Start' comments have been included in the source to highlight and explain the implementation.

Authentication Quick Starts This sample serves two purposes. First, it demonstrates how to create a custom metadata provider that can participate in the RIA Services metadata pipeline. Secondly, the sample also provides a solution to the existing problem of providing additional metadata for types that you don’t own or can’t modify.

Custom Metadata Provider This sample demonstrates how DAL layer can be mocked to Unit Test business logic code implemented in DomainService class. In this sample this is done my implementing a repository pattern, specifically a repository pattern with Linq To SQL as DAL. Instructions on using the sample can be found in the ReadMe doc included with the sample.

Testing Domain Services [demos Repository pattern] This sample demonstrates how to create a RIA Services DomainService Base Class for a particular Data Source or Data Access Layer (DAL). Two such providers ship with the framework already – the LinqToSql and LinqToEntities DomainService base classes. All the APIs and functionality needed to create these providers is public, which supports the creation of providers targeting other sources of data, for example NHibernate, Amazon Web Services ...

Application Samples
Contoso Sales is the RIA Services application demoed at PDC 2009 in Scott Guthrie's Keynote.

Contoso Sales Application CyclingClassifieds sample is an ad-sharing intranet Web-application that lets users browse existing ads and post new ads. This sample demonstrates end to end usage of RIA Services and Silverlight features.

Sample Classifieds Application This simple application demonstrates the use of XML data, a Plain Old CLR Object (POCO) DomainService and Search Engine Optimization (SEO). The ASP.NET DomainDataSource control is used to render content as well as a XML sitemap, all indexable by search engines. The down-level content is only visible to clients viewing the site without the required version of Silverlight installed (or JavaScript disabled).
Since ASP.NET DomainDataSource only supports .NET 4, this sample will only work on the VS 2010 release of RIA Services.

Tools
The tool updates RIA Services VS 2008 projects to VS 2010.
For users upgrading their July CTP VS 2008 project to Dev 2010, it is recommend they first upgrade to the PDC bits on VS 2008 (i.e. consume all the
breaking changes) and then move to Dev 2010.
