PROGRAMMING MODEL IMPROVEMENTS – PART 2 CHANDRAMOULI VENKATESH SESSION CODE : BRK 213 MICROSOFT DYNAMICS AX R & D MICROSOFT CORPORATION

Today we will show you… A new and improved customization paradigm – Eventing Delegate-based events Services programming model improvements Declarative data contract creation using attributes Simplified consumption of AX services by client programs using Service Groups

Components in action today

Pains and challenges Isaac – Business Application Developer Needs to understand sophisticated data model – Relationship information Wants to leverage existing code – Extending existing types is desirable. Needs framework-level support for common application patterns Wants to write efficient code – Enhanced record and object caches Nandita – In-house Developer Wants maintainability of customizations Needs to connect their ERP system with additional business applications on a variety of platforms, such as mobile devices

Typical Steps in Dynamics AX application development FM Inc. ACME 1.Non-intrusive customization patterns 2.Customizations stored as granular metadata 1.Non-intrusive customization patterns 2.Customizations stored as granular metadata

Programmability concepts Tools

When to use the feature Eventing – When developing solutions, raise appropriate events to enable non-intrusive customizations – When customizing, use it to decouple and non-intrusively implement source code customizations – Think twice before you blindly override lower-layer code in a layer above – Services programming model Use it any time you need to expose AX functionality to new clients, including mobile platform clients

Non-intrusive, robust customisation FM Inc. wants to customize the solution to enhance the “Driver License Check” process when a rental clerk checks out a vehicle for a customer Front Office Back Office Fleet

demo ‘No code’ development of data & service contracts

Top 10 tips from the session Eventing must be your preferred choice for implementing source code customization Make no assumptions about the order of invocation of event handlers If an event handler in a chain of event handlers throws an exception, the rest of the handlers are not invoked “Subtractive” customizations are not possible with Eventing Delegate-based events add no performance overhead beyond just a method call Delegate-based events should be preferred over pre-post events Events are akin to an “API,” which implies that you need to think about and commit to remaining backward- compatible on the signature and semantics of an event Services should be your preferred way of accessing AX from external systems Use Datacontract and Datamember attributes to declaratively create data contracts Use service groups to group logically cohesive services together for ease of consumption from the client applications
