Microsoft has released a couple of white-papers around .NET Services a component of the Azure Services Platform. The whitepapers are:
* An Introduction to Microsoft .NET Services for Developers. This overview paper introduces Microsoft® .NET Services, each of its building block services, and how they fit together.
* A Developer’s Guide to the Microsoft® .NET Access Control Service. This whitepaper shows developers how to use a claims-based identity model and the Microsoft® .NET Access Control Service – part of the Microsoft® .NET Services family – to implement single sign-on, federated identity, and role based access control in Web applications and services.
* A Developer’s Guide to the Microsoft® .NET Service Bus. This whitepaper shows developers how to use the .NET Service Bus – part of the Microsoft® .NET Services family – to provide a secure, standards-based messaging fabric to connect applications across the Internet.
* A Developer’s Guide to the Microsoft® .NET Workflow Service. This whitepaper provides details about the Microsoft® .NET Workflow Service, its relation to Windows Workflow Foundation, and what developers need to know to begin building workflows for the cloud. It not only explains the current tools and capabilities but also outlines the vision for future releases.
To give an outline how .NET Services fit in complete Azure Service Platform see picture above. People who attend PDC probably have been following or attending sessions around Windows Azure Services Platform and .NET Services (can be missed actually cause Azure was big announcement). Papers one should read to get better understanding and background knowledge of .NET Services.
