Any SOA Architecture (n-tier) Real-World Samples with .NET for getting started ?

SOA infrastructure is used by many armies and air forces to deploy situational awareness systems. SOA is used to improve healthcare delivery. Nowadays many apps are games and they use inbuilt functions to run. For example, an app might need GPS so it uses the inbuilt GPS functions of the device.
The . NET framework natively supports primitive SOA characteristics through its runtime environment and development tools, as explained here. Through the creation of independent assemblies and ASP.NET applications, the . NET framework supports the notion of partitioning application logic into atomic units.
A Service-Oriented Architecture(SOA) is a loosely-coupled, reusable software component, which encapsulates different functionalities which are distributed and programmatically accessed. It emerged in the 2000s. It is Message-oriented architecture based on XML.
Not long ago, the buzz-phrase "service-oriented architecture" saturated the IT industry, before being overtaken by the cloud. But SOA remains alive and relevant, Forrester Research reported last month. SOA is a software design approach where systems are composed of interoperable "services" featuring reusable code.
I recommend to start a .NET App with WCF. Get related to WCF, its advantages a as to expose a service endpoint with multiple binding as http, tcp, etc, so you are able to SOA your App.
I use the UML Robustness Analysis to discover the functionality that will be exposed as services.
I think that there is not silver bullet code for SOA, SOA is about design, organization of the system methods in order to expose services that orchestrates the handling of the responsibilities of application entities.
For example, to look for a flight booking, your SOA service have to expose a contract, with all necessary data to handle the service request. It will return all necesary data for the next service, book flight.
There is an excelent article about SOA in the Architecture Journal #21 -Service Orientation Today and Tomorrow Article An Enterprise Architecture Strategy for SOA written by Hatay Tuna.
SOA is about logic exposure, design, logic ecapsulation, is not about code, the code supports the orientation.
