Exposing Existing WCF SOAP Services and .NET APIs Through ADO.NET Data Services

Abstract

The reality many enterprises will face when considering adopting ADO.NET Data Services is how to implement this new technology alongside their existing services and components. Unless important reasons exist to start from scratch, many will need to make use of their current investments in the .NET technology stack and the SOAP-based services they have built over the last few years. There can be little business justification in tearing down a working set of existing services just to create RESTful APIs. Indeed, many enterprises will have external clients who consume their SOAP services and cannot be forced to change to a RESTful world. Alternatively, such enterprises may need to expose some or all of their existing services to some clients through SOAP because they rely on WS-*policies for measures such as security. This chapter will cover one such scenario and discuss the measures that architects could take in order to preserve existing investments while benefiting from adding RESTful services to their enterprises. The current architecture in any enterprise is unique and is unlikely to match this example exactly, but some of the patterns used here are commonplace, and the chapter provides commentary throughout to describe some alternative scenarios.
