Microsoft Dynamics AX 2012 Services

Chapter 2. Service Architecture and Deployment

There is always more than one solution for a problem. This is certainly true when designing solutions for your integration scenarios with Microsoft Dynamics AX 2012. As we learned in the previous chapter, there are a lot of options to choose from, both for deployment and development of services. In this chapter, we will focus on the options that are available when deploying services.

The following topics are covered in this chapter:

  • What is WCF?: WCF provides the basis for building, configuring, and deploying services with Microsoft Dynamics AX 2012, so we will discuss the key concepts that are related to WCF.
  • Service deployment: Deployment of services is enabled by integration ports. You will learn how to create, configure, and deploy these integration ports.
  • Service generation: There is a lot going on when services are deployed. We will explore the artifacts that are generated, and learn what CIL is.

What is WCF?

Windows Communication Foundation (WCF) was introduced with the release of .NET Framework 3.0. This release of the framework was in essence the 2.0 version together with four additional components:

  • Windows Presentation Foundation (UI graphical platform)
  • Windows CardSpace (Identity management platform)
  • Windows Workflow Foundation (Workflow platform)
  • Windows Communication Foundation (Communication platform)

Existing technologies

WCF is meant to provide a unified programming model to build, configure, and deploy services on distributed networks. It combines well known technologies that have been around for some time such as .NET remoting , Web Services Enhancements (WSE), MSMQ, ASMX, and message-oriented programming.

Existing technologies

Note

The previous diagram is kindly provided by wcftutorial.net. If our introduction to WCF makes you curious about WCF and its technologies, this website does a great job explaining it in detail.

The ABC of WCF

An elaborate explanation of all the features that WCF has to...

Service deployment

Microsoft Dynamics AX 2012 does a lot to simplify service deployment. Not so much by reducing the number of concepts, but by gradually presenting those concepts to users as they are needed. This is immediately obvious when you look at the setup menu for services and AIF. When you go to System administration | Setup | Services and Application Integration Framework, you only see four options. The first two are the most important: inbound ports and outbound ports . These two types of ports are known as integration ports .

Integration ports provide a way to group services and manage them together. They have at least the following properties:

  • One or more service operations
  • A direction that is inbound or outbound
  • A category that is either basic or enhanced
  • An adapter
  • The address of the port

We will discuss these properties and others in greater detail.

Service operations

An integration port contains one or more service operations. These must be operations from services that all have...

Bindings

When client and service communicate, there are several aspects of the communication:

  • Synchronous/asynchronous: Messages can be used in a request/reply pattern or they can be used in asynchronous communication depending on whether the client waits for the response or not.
  • Transport protocol: The protocol used for transporting the messages can vary depending on the needs. Protocols such as HTTP, Transmission Control Protocol (TCP), Microsoft Message Queuing (MSMQ), and Inter-process communication (IPC) can be used.
  • Encoding: You have the choice on how to encode the messages. You can choose either not to use or use plain text when you want more interoperability. Alternatives are binary encoding to speed up performance or using Message Transport Optimization Mechanism (MTOM) for handling larger payloads.
  • Security: There are also some options that can be used to handle security and authentication. Security can be done not at all, at the transport level, or at the message level.

As you can...

Service generation – under the hood

While services are being deployed when activating integration ports, there is more going on than meets the eye. A service generator written in X++ kicks in and creates the artifacts needed by the AOS to host the WCF services. These artifacts are files containing managed code (C#) and contain the service implementation, message contracts, and a WCF configuration. To explain this, we will take a closer look at one of the out-of-the-box integration ports: the DocumentHandling port.

Generated artifacts

When you take a look at the DocumentHandlingService service node in the AOT, you will find that this service has one method called Create. So when we deploy this service, we expect the following generated artifacts to be able to host the WCF service:

  • A service contract which contains the service's interface
  • An operation contract for the Create service operation
  • Request and response message contracts for each operation used in the implementation of the...

Summary

In this chapter, we familiarized ourselves with the service architecture. We clearly saw that Microsoft has put a lot of effort into providing us with a simplified administration process for services by introducing integration ports. Because a large part of the architecture is built upon WCF, at least a basic understanding of the technologies that are used in WCF is needed.

To enable all these technologies in combination with Microsoft Dynamics AX 2012, compilation into CIL was introduced. This will allow X++ code to be compiled into CIL and benefit from all the advantages the CIL has.

In the next chapter, we will start digging deeper into the AIF services and get some hands-on time by creating our own AIF services.

Key benefits

  • Learn about the Dynamics AX 2012 service architecture.
  • Create your own services using wizards or X++ code
  • Consume existing web services and services you've created yourself

Description

Because an ERP system like Microsoft Dynamics AX 2012 plays a central role in an organization, there will always be the need to integrate it with other applications. In many cases, services are the preferred way of doing this, and Microsoft Dynamics AX 2012 is now more flexible than ever when it comes to the creation and use of these services. Understanding these services will help you identify where they can be used, and do so effectively."Microsoft Dynamics AX 2012 Services" is a hands-on guide that provides you with all the knowledge you will need to implement services with Microsoft Dynamics AX 2012. The step-by-step examples will walk you through many of the tasks that you need to perform frequently when creating and using services."Microsoft Dynamics AX 2012 Services" provides detailed and practical examples for creating and using services that will make it a resource you will consult many times during your implementationsThis book helps you to identify situations where services can be used for your implementations. By providing step-by-step instructions for many of the common tasks, you will gain practical know-how on to get the job done.Easy to follow instructions are provided for all types of services you will encounter. You will learn how to create document services using the AIF Document Service Wizard and how to use X++ to create custom services. You will also learn how to deploy services and web services and how you can consume them in both X++ and .NET. The services are also put to use in the SysOperation framework, which uses services to run business logic and is the new way to create batch processes in Microsoft Dynamics AX 2012.

Who is this book for?

This book is aimed at Dynamics AX developers, both new and experienced with services and Microsoft Dynamics AX 2012. A basic understanding of MorphX and X++ is assumed, but the step-by-step instructions are easy to follow even for beginners. Some examples use C#.NET, so experience with Visual Studio is a plus but not a must.

What you will learn

  • Processing business logic synchronously and asynchronously
  • Using the AIF Document Service Wizard
  • Creating custom services in X++
  • Configuring enhanced integration ports
  • Deploying services using a variety of protocols

A new development book has been published by Packt.If you are developing with Dynamics AX 2012, you'll need this book. For two reasons. Firstly, as you'll need to deal with services. Secondly, because it is a great book.The book is 200 pages, and it does a great job of explaining how to build and how to consume services.I think the book is great for several reasons:*It is technical. The level of contents and technical depth is comparable to Inside Dynamics AX 2012.*It is unique. The contents is written for this book. You will not find it anywhere else.*It is self-contained. Whenever a concept is used, it will be explained - even when it is not directly related to services. So be prepared for excursions to the lands of CIL, WCF, Runbase, AX Security, Visual Studio, UI builders etc.*It is actionable. Each chapter shows step-by-step, line-by-line what to do in various scenarios. Urging you to try it out yourselves.*It is opinionated. I'm not sure how they managed, but the book somehow captures the atmosphere we had when building AX 2012 - we knew we were on to something special. The book deals out appraisals where due, and explains why AX 2012 is a huge leap forward for services.*It is jovial. The tone in the book is welcoming and direct - I think the most used word is "you". This is quite refreshing for a technical book.A big "Thank You!" to the team behind the book for increasing the AX community's knowledge: Klaas Deforche, Kenny Saelen, Palle Agermark, José Antonio Estevan and Tom Van Dyck.

Services development ist each day more important and Microsoft Dynamics Ax 2012 offers between a lot of new technological improvement a quite good services framework which you should learn and master.This book is quite good for that because is quite short but just deliver what you need to know about Dynamics Ax 2012 Services. After reading it you will know all the possibilities that Ax offers you to develop and use services.After reading this book I would consider to read also the official trainning manuals 80416 for Application Integration Framework and you will be the services boss! :-)

This is a small book but full of useful information. Services are a very important part of the standard framework of Microsoft Dynamics AX and it will become mandatory to make use of them for ampliation and comunication of developments over the standard.This books cover all the perspectives around services, including examples of using standard services to publish information out of AX and internally consuming external services from AX and making full use of the new standard SysOperationFramework, including theoric basis of services, full setup of the whole process, using the standard wizards to easilly setup the first versions, full examples of X++ and .NET code, etc.The book easily but fully covers an important feature of this new AX 2012 version that is not covered on other books at the moment. So, it's well worth to make it part of your technical library.

I read this book on the plane flying to my AX consulting gigs. I previously read Microsoft's materials about AIF and should say that this book is a great supplement to them. The book is written much better, gives great examples and covers most of the real-world scenarios of AIF usage. I highly recommend it to all AX developers.

I'm an AX Developer, and I find Packt publishing's Dynamics AX books are great for some extra study while on the weekly commute to/from London. Have just started this book, but so far have enjoyed reading a good overview about the services in this new release of the product - not to fluffy and theoretical, but not necessarily complicated or techie either - just right!

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
