WCF Data Services Processing Pipeline First I must confess. Even tough I like OData and WCF Data Services, in the last couple of months I didn’t have the chance to work or use them. This is why when .NET 4 was shipped I haven’t noticed a new and interesting extension point in the framework – the processing pipeline . In the last MIX11 I got a little introduction to that extension point in Mike Flasko’s session . In this post I’ll explain what is the WCF Data Services' server side processing pipeline...
Making a JSONP Call to a WCF Data Service using datajs During MIX11 I attended a very interesting session about datajs which was presented by Asad Khan and Marcelo Lopez Ruiz. As I promised in my previous post , in this post I’ll show you how to make a JSONP call to a WCF Data Service using datajs library. A Little About datajs datajs is a very promising JavaScript library which is currently being built by Microsoft as an open source in CodePlex. The library as described in its CodePlex site is ...
Configuring WCF Data Services using Lambda Expressions One of the things that I avoid when I’m writing code is the use “magic strings”. Hardcoded strings are a code smell and should be rarely used. When using WCF Data Service configuration object you’ll have to pass the entity set’s string name to the configuration methods which as I wrote I would like to avoid. This is why in today’s post I’m going to extend the DataServiceConfiguration object to support lambda expressions instead of string parameters...
Using EF DbContext with WCF Data Services One of the questions that you may ask yourself with the new EF feature CTP5 is how to embed the new DbContext object inside an OData service or more particularly inside WCF Data Service . This post will supply the solution. DbContext as WCF Data Service Data Source Entity Framework has a good integration with WCF Data Services . All you need to do when you create a WCF Data Service with EF is to put the generated ObjectContext as a data source of the service...
Exposing a Stored Procedure in WCF Data Service Today I answered a question in the data platform development forums. The question was simple – how to expose a stored procedure which is mapped to an Entity Framework model through a WCF Data Service . This post will show you exactly how to do this. The Stored Procedure First I’ve created a the following stored procedure: CREATE PROCEDURE dbo.GetCoursesOrderByTitle AS BEGIN SET NOCOUNT ON SELECT CourseID, Title, Days, [ Time ], Location, Credits, DepartmentID...
OData Session Slide Deck and Demos Yesterday’s evening I delivered an OData session at the Israeli Web Developer Community ( WDC ) user group at Microsoft Ra’anana. The session included the following agenda: The OData need. What is OData ? Creating and consuming OData feeds. I want to thank all the attendees who came to the session. I really enjoyed to deliver the content about OData and the audience was very cooperative with a lot of good questions that helped to highlight many crucial...
OData Session is Occurring Today Today at 17:30 I’m delivering an OData session at Microsoft office in Ra’anana. Come and hear about the Open Data Protocol, a new protocol for exposing and consuming data on the web. The OData ecosystem is a growing community of data producers and consumers using the Open Data Protocol to exchange data. The Open Data Protocol breaks down data silos and increases the shared value of data and its associated business logic through the Web by enabling the exposure of...
