Tips for Creating Services in Microsoft Dynamics AX 2009 - White Paper

While staying on the topic of integrations for Dynamics AX 2009, I wanted to give a link to a great resource that was first released in June of this year.

That is the Tips for Creating Services in Microsoft Dynamics AX 2009 - White Paper

The previous post, of consuming services inside Dynamics AX 2009 was taking and bring in data or working with serviecs from the point of Dynamics AX 2009 to the outside world.

This white paper goes into great details, helps, do's and dont's for creating Services that expose Dynamics AX 2009 to the outside world.

These services can then be consumed by the outside world for working with process, data, and business logic inside Dynamics AX.

Before this white paper came out, there was good help on the web with great blog entries, etc. However this white paper is recommended for anyone that is working with AIF, or will be working with AIF to expose Dynamics AX to the outside world.

From the white paper.:
"Microsoft Dynamics AX services are designed and implemented in the Application Object Tree (AOT) using X++. A service is defined once, but can be exposed via different transport protocols, such as a Web Service, an MSMQ adapter, a BizTalk adapter, or a file system adapter. Microsoft Dynamics AX tools and wizards are available to expose and deploy services to these different environments, leaving the application developer to focus on the service definition and implementation.

The application developer uses tools and wizards to generate and deploy the X++ service as a Windows Communication Foundation (WCF) service hosted in Internet Information Services (IIS). After a service has been implemented, any requests made to that service are forwarded from IIS and run on the Application Object Server (AOS). These generation tools create the service definition in the form of XML Schema Definitions (XSDs) and managed assemblies. From a high level, service requests are made to the managed assemblies that delegate them to the X++ service implementation using .NET Business Connector. The incoming message is not deserialized inside the managed assembly to increase performance."

AIF, in Dynamics AX 2009, comes as part of the base package and should be used for exposing business logic, data and processes to the outside world.

That's all for now, check back soon!
