This course covers how to use ASP.NET Web API to build data services based on the OData protocol, including OData query syntax and OData message formatting. The OData protocol is an open multiplatform standard for exposing data via REST-based HTTP services for querying and updating. The ASP.NET Web API has been extended to allow you to easily build services that enable the OData query syntax on top of whatever formatting you choose for your payloads, or to do full-blown OData with both the query language and OData-compliant formatting. This course will teach you how to implement OData query support and OData formatting for round-trip CRUD (Create-Read-Update-Delete) operations on resource collections exposed using Web API services.
