Silverlight 4 and RIA Services Release Candidate Available NOW

At Mix10 this morning in Vegas ScottGu announced that Silverlight 4 and RIA Services RC are available for download now!  These bits work great with VS2010 RC

We have some great videos, and updated samples already posted on http://silverlight.net/riaservices

Deepesh has a great list of what is new in this drop  RIA Services RC and Toolkit March 2010 now available… and there is the official forum post from DineshKu RIA Services Road to RTW via RC at MIX.

  • INDEI Support:- Validation support based on Silverlight 4’s INotifyDataErrorInfo. This is a non-exception-based model and enables async validations more easily. It also helps display errors flagged by the server in the UI.

  • Spiffier DDS: filter/sort/group descriptors support binding; ICommand support for Load/SubmitChanges/RejectChanges

  • Server throttling: you can regulate the per request load on the server / DB by specifying maximum result limit on a query method using the QueryAttribute.ResultLimit property.

  • AuthorizationContext: Similar to ValidationContext, now you have more options for implementing custom authorization rules (e.g. entity-based authorization)

  • Endpoint configuration support: Following the “secure by default” principle, only binary endpoint will be exposed but we have made it really easy to add additional/different endpoints if you plan to use them.

  • OData endpoint: you can point PowerPivot to a DomainService OData endpoint and analyze data by calling the appropriate query method. This is the first step in lighting up OData with RIA Services

 

Download the bits now and lets us know what you think!
