How to Integrate NuGet Packages into Your Azure Functions?

Leveraging NuGet Packages in Azure Functions

Azure Functions, built on the .NET runtime, seamlessly integrates with NuGet, allowing developers to incorporate external libraries into their C# functions. This simplifies development by providing access to a vast ecosystem of pre-built components.

Specifying Dependencies

To utilize NuGet packages, create a project.json file within your function app. This file lists your dependencies. For example:

<code class="language-json">{
  "frameworks": {
    "net46": {
      "dependencies": {
        "Microsoft.ProjectOxford.Face": "1.1.0"
      }
    }
  }
}</code>

Deploying project.json

You can deploy the project.json file using several methods:

• Azure Function App Portal: Navigate to "View Files," then "Create File." Create a file named project.json and paste your dependency definitions. The Azure Functions runtime automatically handles package restoration.

• Alternative Deployment Methods: For more advanced scenarios, consider these options:

  • App Service Editor (Monaco): Directly upload project.json via the online editor.
  • SCM Endpoint (Kudu): Use the Kudu console or drag-and-drop to upload project.json.
  • FTP: Copy project.json to /site/wwwroot/<function_name>.
  • Continuous Integration/Continuous Deployment (CI/CD): Integrate NuGet package management into your CI/CD pipeline.
  • Pre-compiled Assemblies: Build pre-compiled assemblies in Visual Studio, managing NuGet references within the development environment.

Utilizing Packages in Your Code

Once deployed, simply add using statements for your NuGet packages in your C# code and utilize their functionalities. There's no need for manual assembly referencing.
