Configure Microsoft Dev Box
The process of setting up Microsoft Dev Box involves two distinct phases. In the first phase, platform engineers configure the necessary Microsoft Dev Box resources through the Azure portal. After this phase is complete, users can proceed to the next phase, creating and managing their dev boxes through the developer portal. This quickstart shows you how to complete the first phase.
The following graphic shows the steps required to configure Microsoft Dev Box in the Azure portal.
First, create a dev center and a project to organize dev box resources. Next, create a dev box definition to use when creating dev boxes. Then, create a dev box pool to define the network connection and dev box definition that dev boxes use. Users who have access to a project can create dev boxes from the pools associated with that project.
If you already have a Microsoft Dev Box configured and you want to learn how to create and connect to dev boxes, see Quickstart: Create a dev box by using the developer portal.
Prerequisites
To complete this quickstart, you need:
- An Azure account with an active subscription. If you don't have an Azure subscription, create a free account before you begin.

Create a dev center
To get started with Microsoft Dev Box, you first create a dev center. A dev center in Microsoft Dev Box provides a centralized place to manage a collection of projects, the configuration of available dev box images and sizes, and the networking settings to enable access to organizational resources.
Use the following steps to create a dev center so you can manage your dev box resources:
Sign in to the Azure portal.
In the search box, enter dev centers. In the list of results, select Dev centers.
On the Dev centers page, select Create.
On the Create a dev center pane, on the Basics tab, enter the following values:
Setting Value Subscription Select the subscription in which you want to create the dev center. ResourceGroup Select an existing resource group, or select Create new and then enter a name for the new resource group. Name Enter a name for your dev center. Location Select the location or region where you want the dev center to be created. Attach a quick start catalog Clear both checkboxes. 
For a list of the currently supported Azure locations with capacity, see Frequently asked questions about Microsoft Dev Box.
(Optional) On the Tags tab, enter a name/value pair that you want to assign.
Select Review + Create.
On the Review tab, select Create.
Track the progress of the dev center creation from any page in the Azure portal by opening the Notifications pane.
When the deployment completes, select Go to resource. Confirm that the dev center page appears.
Create a project
Dev box projects enable you to manage team-level settings. These settings include providing access to development teams so developers can create dev boxes. Each dev center needs at least one project.
To create and configure a project in a dev box:
Sign in to the Azure portal.
In the search box, enter projects. In the list of results, select Projects.
On the Projects page, select Create.
On the Create a project pane, on the Basics tab, enter the following values:
Setting Value Subscription Select the subscription in which you want to create the project. Resource group Select an existing resource group, or select Create new and then enter a name for the new resource group. Dev center Select the dev center that you want to associate with this project. All the settings at the dev center level apply to the project. Name Enter a name for the project. Description Enter a brief description of the project. 
On the Dev box management tab, ensure No is selected.
You can select Yes to limit the number of dev boxes per developer, and specify the maximum number of dev boxes a developer can create. The default, No, means developers can create an unlimited number of dev boxes.
To learn more about dev box limits, see Tutorial: Control costs by setting dev box limits on a project.
(Optional) On the Tags tab, enter a name/value pair that you want to assign.
Select Review + Create.
On the Review tab, select Create.
Confirm that the project is created successfully by checking the notifications. Select Go to resource.
Verify that the project appears on the Projects page.
As you create a project, you might see this informational message about catalogs:
Because you're not configuring Deployment Environments, you can safely ignore this message.
Create a dev box definition
Next, you create a dev box definition in your dev center. A dev box definition defines the VM image and the VM SKU (compute size + storage) that are used in the creation of the dev boxes. Depending on the type of development project or developer profiles, you can create multiple dev box definitions. For example, some developers might need a specific developer tool set, whereas others need a cloud workstation that has more compute resources.
The dev box definitions you create in a dev center are available for all projects associated with that dev center. You need to add at least one dev box definition to your dev center.
To create and configure a dev box definition for your dev center:
Open the dev center in which you want to create the dev box definition.
Select Dev box definitions.
On the Dev box definitions page, select Create.
On the Create dev box definition page, enter the following values:
Setting Value Note Name Enter a descriptive name for your dev box definition. Image Select the base operating system for the dev box. You can select an image from Azure Marketplace or from Azure Compute Gallery.
If you're creating a dev box definition for testing purposes, consider using the Visual Studio 2022 Enterprise on Windows 11 Enterprise + Microsoft 365 Apps 22H2 image.To access custom images when you create a dev box definition, you can use Azure Compute Gallery. For more information, see Configure Azure Compute Gallery. Image version Select a specific, numbered version to ensure that all the dev boxes in the pool always use the same version of the image. Select Latest to ensure that new dev boxes use the latest image available. Selecting the Latest image version enables the dev box pool to use the most recent version of your chosen image from the gallery. This approach ensures the created dev boxes stay up to date with the latest tools and code for your image. Existing dev boxes aren't modified when an image version is updated. Compute Select the compute combination for your dev box definition. Storage Select the amount of storage for your dev box definition. Enable hibernation Leave this checkbox unselected. 
Select Create.
Create a dev box pool
Now that you defined a dev box definition in your dev center, you can create a dev box pool in the project. A dev box pool is the collection of dev boxes that have the same settings, such as the dev box definition and network connection. Developers that have access to the project in the dev center, can then choose to create a dev box from a dev box pool.
Dev box pools define the location of the dev boxes through the specified network connection. You can choose to deploy dev boxes to a Microsoft-hosted network or to a network that you manage. If you choose to deploy dev boxes to a network that you manage, you must first configure a network connection. Organizations that support developers in multiple geographical locations can create dev box pools for each location by specifying a nearby region.
To create a dev box pool associated with a project:
Sign in to the Azure portal.
In the search box, enter projects. In the list of results, select Projects.
Open the project in which you want to create the dev box pool.
Select Dev box pools, and then select Create.
On the Create a dev box pool pane, enter the following values:
Setting Value Name Enter a name for the pool. The pool name is visible to developers to select when they're creating dev boxes. The name must be unique within a project. Dev box definition Select an existing dev box definition. The definition determines the base image and size for the dev boxes that are created in this pool. Network connection 1. Select Deploy to a Microsoft hosted network.
2. Select your desired deployment region for the dev boxes. Choose a region close to your expected dev box users for the optimal user experience.Dev box Creator Privileges Select Local Administrator or Standard User. Enable Auto-stop Yes is the default. Select No to disable an auto-stop schedule. You can configure an auto-stop schedule after the pool is created. Stop time Select a time to shut down all the dev boxes in the pool. All dev boxes in this pool shut down at this time every day. Time zone Select the time zone for the stop time. Licensing Select this checkbox to confirm that your organization has Azure Hybrid Benefit licenses that you want to apply to the dev boxes in this pool. 
Select Create.
Verify that the new dev box pool appears in the list. You might need to refresh the screen.
The Azure portal deploys the dev box pool and runs health checks to ensure that the image and network pass the validation criteria for dev boxes. The following screenshot shows four dev box pools, each with a different status.
Provide access to a dev box project
Before users can create dev boxes based on the dev box pools in a project, you must provide access for users through role assignments. The Dev Box User role enables dev box users to create, manage, and delete their own dev boxes. You grant access for the user at the level of the project.
To assign roles:
Sign in to the Azure portal.
In the search box, enter projects. In the list of results, select Projects.
Select the project that you want to give team members access to.
On the left menu, select Access control (IAM).
On the command bar, select Add > Add role assignment.
Assign the following role. For detailed steps, see Assign Azure roles using the Azure portal.
Setting Value Role Select DevCenter Dev Box User. Assign access to Select User, group, or service principal. Members Select the users or groups that you want to be able to access to the project. 
The user can now view the project and all the pools within it. The user can create dev boxes from any of the pools and manage those dev boxes from the developer portal.
