Build automation that uses Microsoft-hosted agents and Azure Pipelines

In Microsoft Azure DevOps, you can automate the process of building X++ code and creating deployable packages on any Windows build agent. These agents include Microsoft-hosted agents. This approach helps you avoid the setup, maintenance, and cost of deploying build virtual machines (VMs). It also lets you reuse the existing setup of build agents to run other .NET build automation.

Prerequisites for building X++ code

Build projects

To use .NET tools to build X++ in Azure DevOps, the Microsoft Build Engine (MSBuild) and custom X++ targets are used. Your X++ source code repository must contain an X++ project for each package that you have to build.

You can optionally use a solution file to group the projects, including C# project dependencies, and provide an explicit build order. If the repository doesn't already contain a project, you can create a project in Visual Studio.

Ensure that a descriptor folder exists, and that the descriptor file for each model is checked into your model metadata folder in Azure DevOps.

NuGet packages

NuGet packages are used for the Azure DevOps build pipelines. They include the tools that are required to build X++ code, such as the X++ compiler (xppc.exe), the Application Platform and Application Suite modules, and other modules.

The following NuGet packages are available in the Shared asset library in Microsoft Dynamics 365 Lifecycle Services:

• Microsoft.Dynamics.AX.Platform.CompilerPackage

  • This package contains the X++ compiler and related tools that are required to do a build.
  • The name of the package is typically PUXX/10.X.XX – Compiler Tools.

• Microsoft.Dynamics.AX.Platform.DevALM.BuildXpp

  • This package contains the compiled X++ code for the Application Platform module and related modules. This code is optimized for building.
  • The name of the package is typically PUXX/10.X.XX – Platform Build Reference.

• Microsoft.Dynamics.AX.Application1.DevALM.BuildXpp

  • This package contains the compiled X++ code for the Application module and related modules. This code is optimized for building.
  • The name of the package is typically PUXX/10.X.XX – Application 1 Build Reference.

• Microsoft.Dynamics.AX.Application2.DevALM.BuildXpp

  • This package contains the compiled X++ code for the Application module and related modules. This code is optimized for building.
  • The name of the package is typically PUXX/10.X.XX – Application 2 Build Reference.

• Microsoft.Dynamics.AX.ApplicationSuite.DevALM.BuildXpp

  • This package contains the compiled X++ code for the Application Suite module. This code is optimized for building.
  • The name of the package is typically PUXX/10.X.XX – Application Suite Build Reference.

Install NuGet packages

Follow these steps to complete the NuGet package installation.

1. Create a feed. Learn more in Create a feed.

2. Connect to the feed. In the Project setup section, select the Copy button to copy the nuget.config XML to the clipboard. Learn more in Connect to a feed.

3. In Notepad, create a new file, paste the XML that you copied in the previous step, and save the file as nuget.config.

4. In your Azure DevOps project, go to your code repository for Dynamics 365 finance and operations apps.

5. Upload the nuget.config file that you created in the previous step to your repository. The nuget.config file can be stored anywhere in source control, because the path is defined in variables in the build pipeline. However, we recommend a simple location, such as Trunk/Main/Projects.

6. Download NuGet. Save it to the folder where the NuGet packages that you previously downloaded from Lifecycle Services are located.

7. Publish each Dynamics 365 NuGet package by using the command for project-scoped feeds in Publish packages. For example, the command for the compiler package resembles this code.

   nuget.exe push -Source https://pkgs.dev.azure.com/<orgname>/<projectname>/_packaging/<feedname>/nuget/v3/index.json -ApiKey AZ Microsoft.Dynamics.AX.Platform.CompilerPackage.nupkg
   

8. Confirm that the packages were published by verifying that the five NuGet packages are in your Azure DevOps project artifacts.

Use NuGet packages in a build pipeline

In a build pipeline, two files are used to identify the packages and specify where they can be found. One of the files is a nuget.config file, and the other is a packages.config file. The paths of these files are explicit inputs for the NuGet command and can be defined in the variable section of the build pipeline.

The nuget.config file gives NuGet the source feed where the packages can be found. You created it in the Install NuGet packages section of this article.

The packages.config file specifies the packages and their versions. To build against a newer version, update the versions in the packages.config file. The package.config file is manually created.

The following example shows a packages.config file that contains the main packages that are required for a typical X++ build.

<?xml version="1.0" encoding="utf-8"?>
<packages>
    <package id="Microsoft.Dynamics.AX.Platform.DevALM.BuildXpp" version="7.0.7279.40" targetFramework="net40" />
    <package id="Microsoft.Dynamics.AX.Application1.DevALM.BuildXpp" version="10.0.1935.21" targetFramework="net40" />
    <package id="Microsoft.Dynamics.AX.Application2.DevALM.BuildXpp" version="10.0.1935.21" targetFramework="net40" />
    <package id="Microsoft.Dynamics.AX.ApplicationSuite.DevALM.BuildXpp" version="10.0.1935.21" targetFramework="net40" />
    <package id="Microsoft.Dynamics.AX.Platform.CompilerPackage" version="7.0.7279.40" targetFramework="net40" />
</packages>

Follow these steps to create a packages.config so that you can use NuGet packages in a build pipeline.

1. Copy the preceding XML.
2. In Notepad, create a new file, and paste the XML that you copied in the previous step. Replace the example version numbers with the actual versions of your NuGet packages.
3. Save the file as packages.config.
4. In your Azure DevOps project, go to your code repository for finance and operations apps.
5. Upload the packages.config file to your Azure DevOps repository. The packages.config file can be stored anywhere in source control, because the path is defined in variables in the build pipeline. However, for the sake of simplicity, we recommend that you use the same location that you used for the nuget.config file (for example, Trunk/Main/Projects).

Creating the pipeline

Azure DevOps provides pipelines that can be used to automate builds. There are two types of pipelines: YML and Classic. YML pipelines are available only when you use Git source control repositories. Classic pipelines must be used to build Team Foundation Version Control (TFVC) repositories. Learn more in YAML vs Classic Pipelines.

This section describes the steps that are required in a pipeline to build X++ code.

Create a basic build pipeline from a template (preferred method)

Follow these steps to create a build pipeline.

1. Download the xpp-classic-ci.json file from the Dynamics365-Xpp-Samples-Tools GitHub repository.

2. In Azure DevOps, select Pipelines.

3. Select the three vertical dots, and then select Import a pipeline on the menu. Browse to the .json file that you downloaded in the previous step, and import it.

   Note

   To use Classic pipelines, in Azure DevOps, go to Organization settings > Pipelines > Settings, and confirm that both the following settings are disabled (turned off):

   • Disable creation of classic build pipelines
   • Disable creation of classic release pipelines

4. The imported pipeline is automatically opened. In the pipeline settings, name your pipeline, set the agent pool, and set the agent specification to windows-latest.

5. Select Get sources, and set the source to TFVC. The Workspace mappings section is opened.

6. Select the ellipsis (…) button next to the Server path field, and then select the folder that contains the metadata and projects folders. For example, the folder might be $/<RepoName>/Trunk/Main.

7. On the Variables tab, confirm that NugetConfigPath points to the location where the nuget.congig is saved in your Dynamics 365 finance and operations repository. For example, the location might be $(Build.SourcesDirectory)\Projects.

8. In the Build solution task, set your Visual Studio solution to Visual Studio 2022 or the latest version.

9. Save the pipeline.

Manually create a basic build pipeline

A basic pipeline for compiling X++ and creating a deployable package requires several steps. The pipeline should include a versioning step and a packaging step.

Before you can add the necessary steps to a pipeline to create a deployable package for finance and operations apps, the Dynamics 365 finance and operations Tools extension for Azure DevOps must be enabled and installed in the Azure DevOps organization. Learn how to install an extension for an organization in the Azure DevOps documentation.

The following six tasks must be added to the pipeline agent job:

1. Install the NuGet packages
2. Update the model versions.
3. Build the solution or projects.
4. Install NuGet 3.3.0 or earlier on the agent
5. Create the deployable package
6. Publish the deployable package

Task 1. Install the NuGet packages

To install the NuGet packages, you can use the NuGet task and change it to a custom command in the task properties. The custom command should resemble this code.

install -Noninteractive $(NugetConfigsPath)\packages.config -ConfigFile $(NugetConfigsPath)\nuget.config -Verbosity Detailed -ExcludeVersion -OutputDirectory "$(NugetsPath)" 

Task 2. Update the model versions

Install and update the Update the model versions task by following the instructions in Update the model versions.

Task 3. Build the solution or projects

The Visual Studio build task lets you select the Visual Studio version that is used to build the solution or projects. Before you can use the task, the MSBuild arguments in the task must be populated.

The following table describes the variables that are used in the MSBuild arguments.

The following example shows a value that can be used for the MSBuild arguments.

/p:BuildTasksDirectory="$(Pipeline.Workspace)\NuGets\Microsoft.Dynamics.AX.Platform.CompilerPackage\DevAlm"
/p:MetadataDirectory="$(Build.SourcesDirectory)\Metadata"
/p:FrameworkDirectory="$(Pipeline.Workspace)\NuGets\Microsoft.Dynamics.AX.Platform.CompilerPackage"
/p:ReferenceFolder="$(Pipeline.Workspace)\NuGets\Microsoft.Dynamics.AX.Platform.DevALM.BuildXpp\ref\net40;$(Pipeline.Workspace)\NuGets\Microsoft.Dynamics.AX.Application1.DevALM.BuildXpp\ref\net40;$(Pipeline.Workspace)\NuGets\Microsoft.Dynamics.AX.Application2.DevALM.BuildXpp\ref\net40;$(Pipeline.Workspace)\NuGets\Microsoft.Dynamics.AX.ApplicationSuite.DevALM.BuildXpp\ref\net40;$(Build.SourcesDirectory)\Metadata;$(Build.BinariesDirectory)"
/p:ReferencePath="$(Pipeline.Workspace)\NuGets\Microsoft.Dynamics.AX.Platform.CompilerPackage" /p:OutputDirectory="$(Build.BinariesDirectory)"

The preceding example of MSBuild arguments assumes that the NuGet packages are installed in $(Pipeline.Workspace)\NuGets, the X++ source code is in $(Build.SourcesDirectory)\Metadata, and the output of the compiler should go in $(Build.BinariesDirectory).

In the pipeline samples, variables for NuGet package names and paths are used to simplify these commands.

Task 4. Install NuGet 3.3.0 or earlier on the agent

This step is required for the step that creates the deployable package. The deployable package can be created only if NuGet is readily available on the build agent. Therefore, the NuGet tool installer task in Azure DevOps must be run before the step that creates the deployable package.

Task 5. Create the deployable package

Follow the instructions in Create deployable packages in Azure Pipelines.

Task 6. Publish the deployable package

Add the Publish build artifacts task to your build pipeline.

Sample pipeline for X++ developers

In the Dynamics365-Xpp-Samples-Tools GitHub repository, you can find a sample pipeline that can be imported into an existing Azure DevOps project.
