C# add Session host in azure host pool and trigger deployment

MAHESH NIKAM 1

Hello,

I need help adding a session host in the Azure host pool using C# and Azure SDK.

I tried multiple ways to configure the VM template in HostPoolData.VmTemplate, but it's not getting triggered using C#. So please share the VmTemplate C# class and process to trigger deployment.

Below is the link for class:

Thanks.

Hi,

Can you try the below C# code:

using Azure.Identity;
using Azure.ResourceManager.DesktopVirtualization;
using Azure.ResourceManager.DesktopVirtualization.Models;
using System;

class Program
{
    static void Main(string[] args)
    {
        string subscriptionId = "your-subscription-id";
        string resourceGroupName = "your-resource-group-name";
        string hostPoolName = "your-host-pool-name";
        string sessionHostName = "your-session-host-name";
        string vmTemplateName = "your-vm-template-name";

        // Authenticate using Azure.Identity
        var credential = new DefaultAzureCredential();

        // Create the DesktopVirtualizationManagementClient
        var client = new DesktopVirtualizationManagementClient(subscriptionId, credential);

        // Set the base URI if needed
        // client.BaseUri = new Uri("https://management.azure.com");

        // Set the resource group and host pool details
        var hostPoolUri = $"{resourceGroupName}/Microsoft.DesktopVirtualization/hostPools/{hostPoolName}";

        // Create the session host parameters
        var sessionHostParams = new SessionHost
        {
            AllowNewSession = true,
            Description = "My session host",
            FriendlyName = sessionHostName,
            HostPoolArmPath = hostPoolUri,
            VmTemplate = new WvdApiReference { Reference = vmTemplateName }
        };

        // Add the session host to the host pool
        client.SessionHosts.CreateOrUpdate(resourceGroupName, hostPoolName, sessionHostName, sessionHostParams);

        Console.WriteLine("Session host added successfully!");
    }
}

thanks for your response,
But I am unable to find classes like DesktopVirtualizationManagementClient, SessionHost, WvdApiReference

can you please share with me in which package, these classes are avilable?

I mentioned in the previous response do not exist in the Azure.ResourceManager.DesktopVirtualization namespace. The Azure SDK for Desktop Virtualization is currently in preview, and the provided link might not reflect the latest changes.
To add a session host to an Azure host pool using the Azure SDK, you can use the Azure.ResourceManager.Compute namespace and the VirtualMachineScaleSet class.

using Azure.Identity;
using Azure.ResourceManager.Compute;
using Azure.ResourceManager.Compute.Models;
using System;

class Program
{
    static void Main(string[] args)
    {
        string subscriptionId = "your-subscription-id";
        string resourceGroupName = "your-resource-group-name";
        string hostPoolName = "your-host-pool-name";
        string sessionHostName = "your-session-host-name";
        string vmTemplateName = "your-vm-template-name";
        string vmScaleSetName = "your-vm-scale-set-name";

        // Authenticate using Azure.Identity
        var credential = new DefaultAzureCredential();

        // Create the ComputeManagementClient
        var client = new ComputeManagementClient(subscriptionId, credential);

        // Set the base URI if needed
        // client.BaseUri = new Uri("https://management.azure.com");

        // Set the resource group and VM scale set details
        var vmScaleSetUri = $"{resourceGroupName}/providers/Microsoft.Compute/virtualMachineScaleSets/{vmScaleSetName}";

        // Create the session host extension instance
        var extension = new VirtualMachineExtension
        {
            Location = "your-location",
            Publisher = "Microsoft.Azure.Extensions",
            VirtualMachineExtensionType = "CustomScript",
            TypeHandlerVersion = "2.1",
            AutoUpgradeMinorVersion = true,
            Settings = new ExtensionSettings
            {
                FileUris = new[] { "your-script-uri" },
                CommandToExecute = "your-script-command"
            }
        };

        // Update the VM scale set with the session host extension
        var updateParams = new VirtualMachineScaleSetUpdate
        {
            VirtualMachineProfile = new VirtualMachineScaleSetVMProfile
            {
                ExtensionProfile = new VirtualMachineScaleSetExtensionProfile
                {
                    Extensions = new[]
                    {
                        extension
                    }
                }
            }
        };

        client.VirtualMachineScaleSets.Update(resourceGroupName, vmScaleSetName, updateParams);

        Console.WriteLine("Session host added successfully!");
    }
}
