Microsoft Azure Compute management client library for .NET

Article
08/27/2024

Microsoft Azure Compute provides the infrastructure to host apps. Tap in to compute capacity in the cloud and scale on demand. Containerize your applications, deploy Windows and Linux virtual machines (VMs), and take advantage of flexible options for migrating VMs to Azure. With comprehensive support for hybrid environments, deploy how and where you want to. Azure compute also includes a full-fledged identity solution, so you gain managed end-point protection, and Active Directory support that helps secure access to on-premises and cloud apps. Deploy great apps and save with pay-as-you-go pricing, and the Azure Hybrid Benefit.

This library supports managing Microsoft Azure Compute resources.

This library follows the new Azure SDK guidelines, and provides many core capabilities:

- Support MSAL.NET, Azure.Identity is out of box for supporting MSAL.NET.
- Support [OpenTelemetry](https://opentelemetry.io/) for distributed tracing.
- HTTP pipeline with custom policies.
- Better error-handling.
- Support uniform telemetry across all languages.

Getting started

Install the package

Install the Microsoft Azure Compute management library for .NET with NuGet:

dotnet add package Azure.ResourceManager.Compute

Prerequisites

You must have an Microsoft Azure subscription.

Authenticate the Client

The default option to create an authenticated client is to use DefaultAzureCredential. Since all management APIs go through the same endpoint, in order to interact with resources, only one top-level ArmClient has to be created.

To authenticate to Azure and create an ArmClient, do the following code:

using Azure.Core;
using Azure.Identity;
using Azure.ResourceManager;

ArmClient armClient = new ArmClient(new DefaultAzureCredential());

More documentation for the Azure.Identity.DefaultAzureCredential class can be found in this document.

Examples

Create an availability set

Before creating an availability set, we need to have a resource group.

ArmClient armClient = new ArmClient(new DefaultAzureCredential());
SubscriptionResource subscription = await armClient.GetDefaultSubscriptionAsync();
ResourceGroupCollection rgCollection = subscription.GetResourceGroups();
// With the collection, we can create a new resource group with an specific name
string rgName = "myRgName";
AzureLocation location = AzureLocation.WestUS2;
ArmOperation<ResourceGroupResource> lro = await rgCollection.CreateOrUpdateAsync(WaitUntil.Completed, rgName, new ResourceGroupData(location));
ResourceGroupResource resourceGroup = lro.Value;

AvailabilitySetCollection availabilitySetCollection = resourceGroup.GetAvailabilitySets();
string availabilitySetName = "myAvailabilitySet";
AvailabilitySetData input = new AvailabilitySetData(location);
ArmOperation<AvailabilitySetResource> lro = await availabilitySetCollection.CreateOrUpdateAsync(WaitUntil.Completed, availabilitySetName, input);
AvailabilitySetResource availabilitySet = lro.Value;

Get all availability set in a resource group

// First, initialize the ArmClient and get the default subscription
ArmClient armClient = new ArmClient(new DefaultAzureCredential());
// Now we get a ResourceGroupResource collection for that subscription
SubscriptionResource subscription = await armClient.GetDefaultSubscriptionAsync();
ResourceGroupCollection rgCollection = subscription.GetResourceGroups();

string rgName = "myRgName";
ResourceGroupResource resourceGroup = await rgCollection.GetAsync(rgName);
// First, we get the availability set collection from the resource group
AvailabilitySetCollection availabilitySetCollection = resourceGroup.GetAvailabilitySets();
// With GetAllAsync(), we can get a list of the availability sets in the collection
AsyncPageable<AvailabilitySetResource> response = availabilitySetCollection.GetAllAsync();
await foreach (AvailabilitySetResource availabilitySet in response)
{
    Console.WriteLine(availabilitySet.Data.Name);
}

Update an availability set

// First, initialize the ArmClient and get the default subscription
ArmClient armClient = new ArmClient(new DefaultAzureCredential());
// Now we get a ResourceGroupResource collection for that subscription
SubscriptionResource subscription = await armClient.GetDefaultSubscriptionAsync();
ResourceGroupCollection rgCollection = subscription.GetResourceGroups();

// With the collection, we can create a new resource group with an specific name
string rgName = "myRgName";
ResourceGroupResource resourceGroup = await rgCollection.GetAsync(rgName);
AvailabilitySetCollection availabilitySetCollection = resourceGroup.GetAvailabilitySets();
string availabilitySetName = "myAvailabilitySet";
AvailabilitySetResource availabilitySet = await availabilitySetCollection.GetAsync(availabilitySetName);
// availabilitySet is an AvailabilitySetResource instance created above
AvailabilitySetPatch update = new AvailabilitySetPatch()
{
    PlatformFaultDomainCount = 3
};
AvailabilitySetResource updatedAvailabilitySet = await availabilitySet.UpdateAsync(update);

Delete an availability set

// First, initialize the ArmClient and get the default subscription
ArmClient armClient = new ArmClient(new DefaultAzureCredential());
// Now we get a ResourceGroupResource collection for that subscription
SubscriptionResource subscription = await armClient.GetDefaultSubscriptionAsync();
ResourceGroupCollection rgCollection = subscription.GetResourceGroups();

// With the collection, we can create a new resource group with an specific name
string rgName = "myRgName";
ResourceGroupResource resourceGroup = await rgCollection.GetAsync(rgName);
AvailabilitySetCollection availabilitySetCollection = resourceGroup.GetAvailabilitySets();
string availabilitySetName = "myAvailabilitySet";
AvailabilitySetResource availabilitySet = await availabilitySetCollection.GetAsync(availabilitySetName);
// delete the availability set
await availabilitySet.DeleteAsync(WaitUntil.Completed);

Check if availability set exists

If you just want to verify if the availability set exists, you can use the function CheckIfExists.

ArmClient armClient = new ArmClient(new DefaultAzureCredential());
SubscriptionResource subscription = await armClient.GetDefaultSubscriptionAsync();
ResourceGroupCollection rgCollection = subscription.GetResourceGroups();

string rgName = "myRgName";
ResourceGroupResource resourceGroup = await rgCollection.GetAsync(rgName);
string availabilitySetName = "myAvailabilitySet";
bool exists = await resourceGroup.GetAvailabilitySets().ExistsAsync(availabilitySetName);

if (exists)
{
    Console.WriteLine($"Availability Set {availabilitySetName} exists.");
}
else
{
    Console.WriteLine($"Availability Set {availabilitySetName} does not exist.");
}

Add a tag to an availability set

// First, initialize the ArmClient and get the default subscription
ArmClient armClient = new ArmClient(new DefaultAzureCredential());
// Now we get a ResourceGroupResource collection for that subscription
SubscriptionResource subscription = await armClient.GetDefaultSubscriptionAsync();
ResourceGroupCollection rgCollection = subscription.GetResourceGroups();

string rgName = "myRgName";
ResourceGroupResource resourceGroup = await rgCollection.GetAsync(rgName);
AvailabilitySetCollection availabilitySetCollection = resourceGroup.GetAvailabilitySets();
string availabilitySetName = "myAvailabilitySet";
AvailabilitySetResource availabilitySet = await availabilitySetCollection.GetAsync(availabilitySetName);
// add a tag on this availabilitySet
AvailabilitySetResource updatedAvailabilitySet = await availabilitySet.AddTagAsync("key", "value");
