Overview of this book

Odata (Open Data Protocol) is a Web protocol for querying and updating data that provides a way to unlock your data and free it from silos that exist in applications today. OData enables data access among a variety of applications, services, and stores by adopting existing Web technologies such as HTTP, XML, and JSON. This book deals with common OData programming cases over the Microsoft .NET Framework platform and eases the learning curve for a .NET developer to start incorporating OData in data service development.This book provides a collection of recipes that help .NET developers to get familiar with OData programming in a quick and efficient manner. The recipes cover most OData features from the former ADO.NET Data Service to the current WCF Data Service platform. In addition, all the sample cases here are based on real-world scenarios and issues that .NET developers might come across when programming with OData in application development.This book will be your handy guide with basic to advanced walkthroughs of common OData programming cases for the Microsoft .NET Framework platform. You will learn quick solutions to necessary tasks to integrate the power of OData at both server-side and client-side.This book will help you master the use of OData with .NET Framework by taking you through hands-on and practical recipes. It starts by talking about the common means for building OData services and consuming OData services in client applications. Then, some more specific topics like hosting, configuration and security are discussed. The book also covers many popular and interesting topics such as integrating OData in web applications, and developing data-driven mobile applications with OData. Moreover, you can also find quite a few recipes discussing real-world OData producers and new features in latest and future versions.Within "OData Programming Cookbook for .NET Developers", all the recipes are selected based on real-world scenarios that you will commonly come across. Each recipe covers a specific topic, going from the description of the problem, through a conceptual solution, to a solution containing sample code. By following these recipes, you can acquire how to program with OData in a simple, effective, and easy manner.

Chapter 1. Building OData Services

In this chapter we will cover:

  • Building an OData service via WCF Data Service and ADO.NET Entity Framework

  • Building an OData service with WCF Data Service and LINQ to SQL

  • Exposing OData endpoints from WCF RIA Service

  • Adding custom operations on OData service

  • Exposing database stored procedures in WCF Data Service

  • Using custom data objects as the data source of WCF Data Service

  • Using Interceptors to customize a WCF Data Service

  • Accessing ASP.NET context data in WCF Data Service

  • Creating a custom WCF Data Service provider

Introduction

Open Data Protocol (OData) is a web protocol for querying and updating data, which can be freely incorporated in various kinds of data access applications. OData makes itself quite simple and flexible to use by applying and building upon existing well-defined technologies, such as HTTP, XML, AtomPub, and JSON.

WCF Data Service is the main component for building OData service on .NET Framework platform. WCF Data Service supports exposing various data source models such as ADO.NET Entity Framework, LINQ to SQL, and CLR Objects through OData service endpoints. Also, we're not limited to these existing data models, we can build our own custom Data Service Provider or convert other services (such as WCF RIA service) to OData service. In this chapter, we will demonstrate several cases of using WCF Data Service to build OData services that can deal with different kinds of data source models.
