Azure Compute Management client library for .NET

This package follows the new Azure SDK guidelines,which provide core capabilities that are shared amongst all Azure SDKs, including:

• The intuitive Azure Identity library.
• An HTTP pipeline with custom policies.
• Error handling.
• Distributed tracing.

Getting started

Install the package

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

Install-Package Azure.ResourceManager.Compute -Version 1.0.0-beta.7

Prerequisites

Set up a way to authenticate to Azure with Azure Identity.

Some options are:

• Through the Azure CLI Login.
• Via Visual Studio.
• Setting Environment Variables.

More information and different authentication approaches using Azure Identity can be found in this document.

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:

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

// Code omitted for brevity

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

Additional 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");

Troubleshooting

• If you find a bug or have a suggestion, file an issue via GitHub issues and make sure you add the "Preview" label to the issue.
• If you need help, check previous questions or ask new ones on StackOverflow using azure and .NET tags.
• If having trouble with authentication, go to DefaultAzureCredential documentation
