Silverlight TV 41: Top Tips for WCF RIA Services

John Papa — Thu, 19 Aug 2010 16:00:00 GMT

On this episode, Dinesh Kulkarni shares his top tips for creating streamlined and performant WCF RIA Services applications. He walks through some key decision points while creating domain services (server side) for a Silverlight and RIA Services application. Among the tips Dinesh discusses are some of the benefits of creating the minimal number of entities, operations, and amount of data required for your application. He also discusses how to connect RIA Services to:

Entity Framework
LINQ to SQL
nHibernate
Your own custom business objects

Other topics Dinesh walks step-by-step through include:

hooking RIA Services up to your own POCO classes
adding role-based authorization
how to determine what objects will be exposed by RIA Services to the client
adding validation
identifying keys and associations for entities
indicating when to return object graphs
how to use the Composite attribute to bundle objects graphs

This is a great deep dive by one of the masterminds behind WCF RIA Services.

Pete at Microsoft: WCF RIA Services Team Interview

Pete Brown — Thu, 17 Jun 2010 10:00:00 GMT

While on campus in May, I met with the WCF RIA Services team at Microsoft. We discussed both the awesome parts and the difficult parts of the recent product release.

Microsoft WCF RIA Services simplifies the traditional n-tier application pattern by bringing together the ASP.NET and Silverlight platforms. RIA Services provides a 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.

Join Pete, Jeff, Dinesh, and Deepesh for a fun talk about this awesome product.

[note, the audio is a little off around 2/3 through, but it clears back up, so stay tuned. I blame the low camera battery. ]

Pete at MIX10: Robert Kihm on Aptify RAD

Pete Brown — Mon, 29 Mar 2010 15:30:00 GMT

While at MIX10, I met up with Robert Kihm, Director of Product Architecture at Aptify. We talked about how Aptify enables you to create metadata for an application as well as surface the UI, including bindings and validation rules across multiple user interfaces (Silverlight and Windows Forms shown), without making any changes.

Building on all the cool things in .NET, Aptify uses Silverlight, WCF RIA Services, SQL Server, Regular WCF SOAP Services, and tons more to help you build cross-technology, cross-platform business applications using Microsoft tools and technologies.

The Aptify Web Site offers more details on the Aptify product.

Silverlight TV 18: WCF RIA Services Validation

John Papa — Thu, 25 Mar 2010 16:00:00 GMT

Just prior to MIX10, Nikhil Kothari appears on the show to demonstrate some of the key advantages around validation when using WCF RIA Services. He demonstrates how to use a Domain Service to expose your domain model and how to create a custom service method to further filter your data server side. Nikhil also shows how the Domain Services generates validation rules using the database attributes such as required fields or maximum string lengths. Other topics Nikhil covers:

Domain service generated services and validation
Custom service methods
Adding your own validation attributes
Creating custom validation methods for server and client
Creating cross property validation in an entity
Creating server only validation that may be called asynchronously from the client

Jeff Handley on WCF RIA Services for Silverlight 4

Pete Brown — Mon, 15 Mar 2010 05:29:00 GMT

In February I popped on over to building 42 and met with my friend, Jeff Handley, who works on the WCF RIA Services team. Jeff talked about what it's like to work on RIA Services, sharing with the community, and openness at Microsoft. Then we chatted a bit about framework development vs. application development and what it means to put something out to the public in released bits.

Jeff and I also talked about what it's like to come back to an office full of popcorn, as well as some tidbits regarding some RIA Services and validation changes coming up as RIA Services takes on INotifyDataErrorInfo vs. the old exception-based validation approach.

Pete at Reykjavik: Silverlight, Azure, RIA Services Event Site in 8 days

Pete Brown — Wed, 10 Feb 2010 20:40:00 GMT

In January, I spoke at the best of tech-ed and Convergence 2010 conference in Reykjavik, Iceland. The event was a huge success, bringing in one out of every 300 people in Iceland (just under 1200 people total)

While there, I met with Sig (Sigurjon Lydsson - Microsoft) and Jon (Gudmundur Jon Halldorsson - Landsbankinn) and talked about the awesome site they built for the event.

The site is 100% Silverlight, powered by WCF RIA Services, with data and app hosted in Azure. They built out the first functional and usable version in 8 days. The site supports registration, general event info, scheduling, speaker bios, track info etc. - everything you'd expect to see in an event site.
