What is the difference between ria and wcf

If your scenario uses EF on the back end and targets Silverlight on the front end, then you are in the best position.

Another consideration is whether you are targeting Silverlight as the client exclusively or not. Of the two, WCF Data Services is relatively lightweight, and requires almost no effort to get up and running. This makes it a very compelling choice for the development of rich client applications.

Although it began as a platform almost exclusively designed for Silverlight, support is steadily emerging for other client platforms via OData, SOAP, and JSON, as well as self-tracking entity libraries now available for jQuery. However, it requires the effort of creating domain service classes to support CRUD operations. Finally, both frameworks are extensible, and both can be secured by traditional authentication and authorization techniques.

They are also both capable of integrating with the ASP. NET Membership provider for role management and personalization. What if you are using neither Silverlight nor Entity Framework? Well, then your work will be cut out for you whatever choice you make. And with WCF RIA Services, you will not get to fully enjoy all the benefits of the framework, but you will still need to write domain services and metadata classes. Here is my answer based on the roadmaps and my understanding of the goals of the RIA Services team.

NET Data Services. The client side data objects are generated using reflection at compile time based on the actual server side objects instead of a service contract. This allows RIA Services to provide a much richer client side object model by including any business rules and relationships between objects. This means that the client can create the LINQ query and have it run server side. The following answer is not by me, but still answer a part of the question that is left unanswered.

WCF Services are operation centric - the main thing you do with these is define operations functions. Data comes as a secondary thing in a way. You have the ability to stricly define what the client can and can not do. WCF Data Services are data centric - the main thing you do with these is define a data model to be exposed. You usually allow clients to decide what they want to do in some boundaries. One of the main differences from WCF Service is that the client can issue a query against the data model think SQL like stuff which the client constructs.

DomainServicesSection, System. DomainServiceHttpModule, System. ODataEndpointFactory, System. Remember to add all the Silverlight pages into View folder.

We need to set the navigation to our newly added Employee. After clicking on the above option we will see the following pane. If you do not have any Domain Service Class then the list would be empty, for some reason if you have one but still you don't get it; you need to rebuild the solution once again.

As you see in the figure above, we have EmployeeDomainContext available to us after we have added the Domain Service Class with respect to Entity Model. Data Sources are used for binding controls with entity; so that the design time can be reduced. As you see in the figure below, we have Employee as an entity and it is preceded with the image of the DataGrid and the properties are preceded with TextBox symbol. That's right, the following controls would be associated once you drag and drop into the design pane.

Visual Studio will do automatic binding with each column type. If the Details view is selected and dropped on to the designer surface, we will get all the controls in a Grid Panel and the default control associated with it is the TextBox control.

You can notice one thing isNote that the Column header name is separated with a space; this is actually a great thing because in previous versions of Visual Studio we had to customize everything on our own.

This is really helpful. We can even change the control for each Column. Let's have different controls for each column in the Details view and see how it is helpful. The following dialog box would be displayed when we select Customize as displayed in above figure. In code behind of the view Employee. We can use the following constructors based on our requirements: By simply calling the method described in EmployeeDomainContext we can achieve the respective operations.

ToString , "Load Error" , System. As you see, in the preceding figure, all Employee data are is displayed. George Updated date Apr 28, In this series of articles, we will discuss the major features of WCF:.

It eases the procedure of building a complex business application in Silverlight by offering client-side validation, where Silverlight is a framework offered by Microsoft, it is a rich internet applications and available for use as a browser plug-in, just like Adobe Flash.

Select Data from the left menu and then ADO. Then, following the steps in the article Entity Framework 2 , With. The created entity only includes two files, one is. Web , Note : a group of System. Web :.
