Azure DevCenter client library for .NET - version 1.0.0

The DevCenter client library provides access to manage resources for Microsoft Dev Box and Azure Deployment Environments. This SDK enables managing developer machines and environments in Azure.

Use the client library for Azure DevCenter to:

Create, access, manage, and delete Dev Box resources Create, deploy, manage, and delete Environment resources

Getting started

Install the package

Install the client library for .NET with NuGet:

dotnet add package Azure.Developer.DevCenter --prerelease


You must have an Azure subscription. In order to take advantage of the C# 8.0 syntax, it is recommended that you compile using the .NET Core SDK 3.0 or higher with a language version of latest. It is also possible to compile with the .NET Core SDK 2.1.x using a language version of preview.

You must have configured a DevCenter, Project, Network Connection, Dev Box Definition, and Pool before you can create Dev Boxes

You must have configured a DevCenter, Project, Catalog, and Environment Type before you can create Environments

Authenticate the client

You can use standard Azure Active Directory Token Credential authentication to access the client. The identity interacting with all resources must have a minimum of Read access on the Project resources it is interacting with. The identity managing Dev Boxes must have the DevCenter Project Admin or DevCenter Dev Box User roles for Dev Box scenarios. These roles can be assigned directly to the project, or inherited from a broader scope (such as the resource group or subscription). To use Azure Active Directory authentication, add the Azure Identity package:

dotnet add package Azure.Identity

You will also need to register a new AAD application, or run locally or in an environment with a managed identity. If using an application, set the values of the client ID, tenant ID, and client secret of the AAD application as environment variables: AZURE_CLIENT_ID, AZURE_TENANT_ID, AZURE_CLIENT_SECRET.

Key concepts

The library uses three main clients. The DevCenterClient provides access to common APIs for interacting with projects and listing resources across projects. The DevBoxesClient is scoped to a single project, and provides access to Dev Box resources such as Pools and Dev Boxes. The DeploymentEnvironmentsClient is scoped to a single project, and provides access to Environments resources such as Environment Definitions, Environment Types, and Environments.

Use these clients to interact with DevCenter resources based on your scenario.

var credential = new DefaultAzureCredential();

var devCenterClient = new DevCenterClient(endpoint, credential);
var devBoxesClient = new DevBoxesClient(endpoint, credential);
var environmentsClient = new DeploymentEnvironmentsClient(endpoint, credential);

Alternatively use DevCenterClient to create DevBoxesClient and DeploymentEnvironmentsClient sharing same endpoint and credential across clients.

devBoxesClient = devCenterClient.GetDevBoxesClient();
environmentsClient = devCenterClient.GetDeploymentEnvironmentsClient();

Thread safety

We guarantee that all client instance methods are thread-safe and independent of each other (guideline). This ensures that the recommendation of reusing client instances is always safe, even across threads.

You can familiarize yourself with different APIs using Samples.

Get all projects in a dev center

DevCenterClient allows you to list projects and retrieve projects by their name.

string devCenterUri = "";
var endpoint = new Uri(devCenterUri);
var credential = new DefaultAzureCredential();
var devCenterClient = new DevCenterClient(endpoint, credential);

List<DevCenterProject> projects = await devCenterClient.GetProjectsAsync().ToEnumerableAsync();
var projectName = projects.FirstOrDefault().Name;

List available Dev Box Pools

Interaction with DevBox pools is facilitated through the DevBoxesClient. Pools can be listed for a specific project or fetched individually.

// Create DevBox-es client from existing DevCenter client
var devBoxesClient = devCenterClient.GetDevBoxesClient();

// Grab a pool
List<DevBoxPool> pools = await devBoxesClient.GetPoolsAsync(projectName).ToEnumerableAsync();
var poolName = pools.FirstOrDefault().Name;

Provision a Dev Box

To create a new DevBox, provide the pool name in the content and specify the desired DevBox name. Upon successful execution of this operation, a DevBox should appear in the portal.

var devBoxName = "MyDevBox";
var devBox = new DevBox(devBoxName, poolName);

Operation<DevBox> devBoxCreateOperation = await devBoxesClient.CreateDevBoxAsync(

devBox = await devBoxCreateOperation.WaitForCompletionAsync();
Console.WriteLine($"Completed provisioning for dev box with status {devBox.ProvisioningState}.");

Connect to your Dev Box

Once a DevBox is provisioned, you can connect to it using an RDP connection string. Below is a sample code that demonstrates how to retrieve it.

RemoteConnection remoteConnection = await devBoxesClient.GetRemoteConnectionAsync(

Console.WriteLine($"Connect using web URL {remoteConnection.WebUri}.");

Delete the Dev Box

Deleting a DevBox is easy. It's much faster operation than creating a new DevBox.

Operation devBoxDeleteOperation = await devBoxesClient.DeleteDevBoxAsync(
await devBoxDeleteOperation.WaitForCompletionResponseAsync();
Console.WriteLine($"Completed dev box deletion.");

Get project catalogs

DeploymentEnvironmentsClient can be used to issue a request to get all catalogs in a project.

// Create deployment environments client from existing DevCenter client
var environmentsClient = devCenterClient.GetDeploymentEnvironmentsClient();

//List all catalogs and grab the first one
//Using foreach, but could also use a List
string catalogName = default;
await foreach (DevCenterCatalog catalog in environmentsClient.GetCatalogsAsync(projectName))
    catalogName = catalog.Name;
Console.WriteLine($"Using catalog {catalogName}");

Get all environment definitions in a project for a catalog

Environment definitions are a part of the catalog associated with your project. If you don't see the expected environment definitions in the results, please ensure that you have pushed your changes to the catalog repository and synchronized the catalog.

//List all environment definition for a catalog and grab the first one
string environmentDefinitionName = default;
await foreach (EnvironmentDefinition environmentDefinition in environmentsClient.GetEnvironmentDefinitionsByCatalogAsync(projectName, catalogName))
    environmentDefinitionName = environmentDefinition.Name;
Console.WriteLine($"Using environment definition {environmentDefinitionName}");

Get all environment types in a project

Issue a request to get all environment types in a project.

//List all environment types and grab the first one
string environmentTypeName = default;
await foreach (DevCenterEnvironmentType environmentType in environmentsClient.GetEnvironmentTypesAsync(projectName))
    environmentTypeName = environmentType.Name;
Console.WriteLine($"Using environment type {environmentTypeName}");

Create an environment

Issue a request to create an environment using a specific definition item and environment type.

var requestEnvironment = new DevCenterEnvironment

// Deploy the environment
Operation<DevCenterEnvironment> environmentCreateOperation = await environmentsClient.CreateOrUpdateEnvironmentAsync(

DevCenterEnvironment environment = await environmentCreateOperation.WaitForCompletionAsync();
Console.WriteLine($"Completed provisioning for environment with status {environment.ProvisioningState}.");

Delete an environment

Issue a request to delete an environment.

Operation environmentDeleteOperation = await environmentsClient.DeleteEnvironmentAsync(
await environmentDeleteOperation.WaitForCompletionResponseAsync();
Console.WriteLine($"Completed environment deletion.");


Errors may occur during Dev Box provisioning due to problems with other resources or your Azure configuration. You can view the operation error or the errorDetails property on the Dev Box if provisioning fails, which will show more information about the problem and how to resolve it. Ensure that your Pool, Network Connection, and Dev Box Definition resources are all in a healthy state before attempting to create a Dev Box. Problems with their configurations will prevent successful creation of your Dev Box.

Errors may occur during Environment deployment due to problems with your template, parameters, or the configuration of other resources. You can view the operation error, which will provide more information about the problem and how to resolve it. Ensure that your Project Environment Type's identity has the correct permissions to the target subscription, that you are passing all parameters which are required by the template, and that all parameters are valid.
