4 - Extension and NuGet feeds

By Nathan Clouse / Sat 05,2026

Before creating any pipelines, you need two marketplace extensions and a NuGet feed containing the X++ compiler packages. This article gets those in place.

Step 1: Install Required Extensions

Your Azure DevOps organization needs two extensions from the Visual Studio Marketplace.
You'll need Organization Administrator permissions to install them.

Power Platform Build Tools

Provides: PowerPlatformToolInstaller@2, PowerPlatformDeployPackage@2, pac CLI

  1. Go to: Power Platform Build Tools
  2. Click Get it free
  3. Select your Azure DevOps organization
  4. Click Install

Dynamics 365 Finance and Operations Tools

Provides: XppUpdateModelVersion@0, XppCreatePackage@2

  1. Go to: Dynamics 365 Finance and Operations Tools
  2. Click Get it free
  3. Select your Azure DevOps organization
  4. Click Install

You can verify both are installed at:
Organization settings > Extensions

Step 2: Create an Azure Artifacts Feed

The build pipeline downloads ~2 GB of X++ compiler packages from a NuGet feed.
Azure Artifacts hosts these within your ADO organization. I suggest you see this related article on ways to automate this here. You can use the linked stategy to get everything uploaded once you have a feed based on a commit and it will generate the packages.config to upload into out repo with code.

  1. In your Azure DevOps project, go to Artifacts
  2. Click + Create Feed
  3. Fill in:
    • Name: D365 (or your preferred name)
    • Visibility: Members of your organization
    • Upstream sources: Uncheck (you'll push packages directly)
  4. Click Create
  5. Note the feed URL — it looks like:
    https://{org}.pkgs.visualstudio.com/{project}/_packaging/{feed}/nuget/v3/index.json

Step 3: Upload DevALM NuGet Packages

You need 6 packages from the LCS Shared Asset Library (or download from a build VM):

Package ID What It Contains
Microsoft.Dynamics.AX.Application.DevALM.BuildXpp Application metadata for compilation
Microsoft.Dynamics.AX.Application1.DevALM.BuildXpp Application layer 1
Microsoft.Dynamics.AX.Application2.DevALM.BuildXpp Application layer 2
Microsoft.Dynamics.AX.ApplicationSuite.DevALM.BuildXpp Application Suite metadata
Microsoft.Dynamics.AX.Platform.CompilerPackage X++ compiler + build tools
Microsoft.Dynamics.AX.Platform.DevALM.BuildXpp Platform metadata for compilation

Getting the Packages

From LCS:

  • Go to LCS > Shared Asset Library > NuGet packages
  • Download each .nupkg file matching your target F&O version

From a Cloud-Hosted Build VM:

  • The packages are already in K:\DeployablePackages\ or the NuGet cache
  • Copy the .nupkg files locally

From Visual Studio:

If you have VS 2022 or newer and the latest version of Finance and Operations tools installed,  you may have an option to download them directly via API. I'll update this section later when this is generally available.

Pushing to Your Feed

# Install the Azure Artifacts Credential Provider if needed
# Then push each package:
nuget push Microsoft.Dynamics.AX.Application.DevALM.BuildXpp.10.0.2428.99.nupkg -Source "D365" -ApiKey az
nuget push Microsoft.Dynamics.AX.Platform.CompilerPackage.7.0.7778.47.nupkg -Source "D365" -ApiKey az
# ... repeat for all 6 packages

The -ApiKey az works with the Azure Artifacts credential provider for authentication.

Step 4: Configure Your Repository

Update src/xpp/build/nuget.config to point at your feed:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <clear />
    <add key="D365" value="https://{org}.pkgs.visualstudio.com/{project}/_packaging/{feed}/nuget/v3/index.json" />
  </packageSources>
</configuration>

Update src/xpp/build/packages.config to match the versions you uploaded:
