Microsoft Azure Mgmt Fabric Dotnet

Azure.ResourceManager.Fabric (.NET)

Management plane SDK for provisioning and managing Microsoft Fabric capacity resources via Azure Resource Manager.

Management Plane Only This SDK manages Fabric capacities (compute resources). For working with Fabric workspaces, lakehouses, warehouses, and data items, use the Microsoft Fabric REST API or data plane SDKs.

Installation

dotnet add package Azure.ResourceManager.Fabric
dotnet add package Azure.Identity

Current Version: 1.0.0 (GA - September 2025)
API Version: 2023-11-01
Target Frameworks: .NET 8.0, .NET Standard 2.0

Environment Variables

AZURE_SUBSCRIPTION_ID=<your-subscription-id> # Required: Azure subscription ID
AZURE_TOKEN_CREDENTIALS=prod  # Required only if DefaultAzureCredential is used in production
AZURE_TENANT_ID=<tenant-id> # For service principal auth (optional)
AZURE_CLIENT_ID=<client-id> # For service principal auth (optional)
AZURE_CLIENT_SECRET=<client-secret> # For service principal auth (optional)

Authentication

using Azure.Identity;
using Azure.ResourceManager;
using Azure.ResourceManager.Fabric;

// Local dev: DefaultAzureCredential. Production: set AZURE_TOKEN_CREDENTIALS=prod or AZURE_TOKEN_CREDENTIALS=<specific_credential>
var credential = new DefaultAzureCredential(
    DefaultAzureCredential.DefaultEnvironmentVariableName
);
// Or use a specific credential directly in production:
// See https://learn.microsoft.com/dotnet/api/overview/azure/identity-readme?view=azure-dotnet#credential-classes
// var credential = new ManagedIdentityCredential();
var armClient = new ArmClient(credential);

// Get subscription
var subscription = await armClient.GetDefaultSubscriptionAsync();

Core Workflows

1. Create Fabric Capacity

using Azure.ResourceManager.Fabric;
using Azure.ResourceManager.Fabric.Models;
using Azure.Core;

// Get resource group
var resourceGroup = await subscription.GetResourceGroupAsync("my-resource-group");

// Define capacity configuration
var administration = new FabricCapacityAdministration(
    new[] { "admin@contoso.com" }  // Capacity administrators (UPNs or object IDs)
);

var properties = new FabricCapacityProperties(administration);

var sku = new FabricSku("F64", FabricSkuTier.Fabric);

var capacityData = new FabricCapacityData(
    AzureLocation.WestUS2,
    properties,
    sku)
{
    Tags = { ["Environment"] = "Production" }
};

// Create capacity (long-running operation)
var capacityCollection = resourceGroup.Value.GetFabricCapacities();
var operation = await capacityCollection.CreateOrUpdateAsync(
    WaitUntil.Completed,
    "my-fabric-capacity",
    capacityData);

FabricCapacityResource capacity = operation.Value;
Console.WriteLine($"Created capacity: {capacity.Data.Name}");
Console.WriteLine($"State: {capacity.Data.Properties.State}");

2. Get Fabric Capacity

// Get existing capacity
var capacity = await resourceGroup.Value
    .GetFabricCapacityAsync("my-fabric-capacity");

Console.WriteLine($"Name: {capacity.Value.Data.Name}");
Console.WriteLine($"Location: {capacity.Value.Data.Location}");
Console.WriteLine($"SKU: {capacity.Value.Data.Sku.Name}");
Console.WriteLine($"State: {capacity.Value.Data.Properties.State}");
Console.WriteLine($"Provisioning State: {capacity.Value.Data.Properties.ProvisioningState}");

3. Update Capacity (Scale SKU or Change Admins)

var capacity = await resourceGroup.Value
    .GetFabricCapacityAsync("my-fabric-capacity");

var patch = new FabricCapacityPatch
{
    Sku = new FabricSku("F128", FabricSkuTier.Fabric),  // Scale up
    Properties = new FabricCapacityUpdateProperties
    {
        Administration = new FabricCapacityAdministration(
            new[] { "admin@contoso.com", "newadmin@contoso.com" }
        )
    }
};

var updateOperation = await capacity.Value.UpdateAsync(
    WaitUntil.Completed,
    patch);

Console.WriteLine($"Updated SKU: {updateOperation.Value.Data.Sku.Name}");

4. Suspend and Resume Capacity

// Suspend capacity (stop billing for compute)
await capacity.Value.SuspendAsync(WaitUntil.Completed);
Console.WriteLine("Capacity suspended");

// Resume capacity
var resumeOperation = await capacity.Value.ResumeAsync(WaitUntil.Completed);
Console.WriteLine($"Capacity resumed. State: {resumeOperation.Value.Data.Properties.State}");

5. Delete Capacity

await capacity.Value.DeleteAsync(WaitUntil.Completed);
Console.WriteLine("Capacity deleted");

6. List All Capacities

// In a resource group
await foreach (var cap in resourceGroup.Value.GetFabricCapacities())
{
    Console.WriteLine($"- {cap.Data.Name} ({cap.Data.Sku.Name})");
}

// In a subscription
await foreach (var cap in subscription.GetFabricCapacitiesAsync())
{
    Console.WriteLine($"- {cap.Data.Name} in {cap.Data.Location}");
}

7. Check Name Availability

var checkContent = new FabricNameAvailabilityContent
{
    Name = "my-new-capacity",
    ResourceType = "Microsoft.Fabric/capacities"
};

var result = await subscription.CheckFabricCapacityNameAvailabilityAsync(
    AzureLocation.WestUS2,
    checkContent);

if (result.Value.IsNameAvailable == true)
{
    Console.WriteLine("Name is available!");
}
else
{
    Console.WriteLine($"Name unavailable: {result.Value.Reason} - {result.Value.Message}");
}

8. List Available SKUs

// List all SKUs available in subscription
await foreach (var skuDetails in subscription.GetSkusFabricCapacitiesAsync())
{
    Console.WriteLine($"SKU: {skuDetails.Name}");
    Console.WriteLine($"  Resource Type: {skuDetails.ResourceType}");
    foreach (var location in skuDetails.Locations)
    {
        Console.WriteLine($"  Location: {location}");
    }
}

// List SKUs available for an existing capacity (for scaling)
await foreach (var skuDetails in capacity.Value.GetSkusForCapacityAsync())
{
    Console.WriteLine($"Can scale to: {skuDetails.Sku.Name}");
}

Key Types Reference

Provisioning and Resource States

Provisioning States (FabricProvisioningState)

• Succeeded - Operation completed successfully
• Failed - Operation failed
• Canceled - Operation was canceled
• Deleting - Capacity is being deleted
• Provisioning - Initial provisioning in progress
• Updating - Update operation in progress

Resource States (FabricResourceState)

• Active - Capacity is running and available
• Provisioning - Being provisioned
• Failed - In failed state
• Updating - Being updated
• Deleting - Being deleted
• Suspending - Transitioning to suspended
• Suspended - Suspended (not billing for compute)
• Pausing - Transitioning to paused
• Paused - Paused
• Resuming - Resuming from suspended/paused
• Scaling - Scaling to different SKU
• Preparing - Preparing resources

Best Practices

1. Use WaitUntil.Completed for operations that must finish before proceeding
2. Use WaitUntil.Started when you want to poll manually or run operations in parallel
3. Use DefaultAzureCredential — never hardcode credentials
4. Handle RequestFailedException for ARM API errors
5. Use CreateOrUpdateAsync for idempotent operations
6. Suspend when not in use — Fabric capacities bill for compute even when idle
7. Check provisioning state before performing operations on a capacity
8. Use appropriate SKU — Start small (F2/F4) for dev/test, scale up for production

Error Handling

using Azure;

try
{
    var operation = await capacityCollection.CreateOrUpdateAsync(
        WaitUntil.Completed, capacityName, capacityData);
}
catch (RequestFailedException ex) when (ex.Status == 409)
{
    Console.WriteLine("Capacity already exists or conflict");
}
catch (RequestFailedException ex) when (ex.Status == 400)
{
    Console.WriteLine($"Invalid configuration: {ex.Message}");
}
catch (RequestFailedException ex) when (ex.Status == 403)
{
    Console.WriteLine("Insufficient permissions or quota exceeded");
}
catch (RequestFailedException ex)
{
    Console.WriteLine($"ARM Error: {ex.Status} - {ex.ErrorCode}: {ex.Message}");
}

Common Pitfalls

1. Capacity names must be globally unique — Fabric capacity names must be unique across all Azure subscriptions
2. Suspend doesn't delete — Suspended capacities still exist but don't bill for compute
3. SKU changes may require downtime — Scaling operations can take several minutes
4. Admin UPNs must be valid — Capacity administrators must be valid Azure AD users
5. Location constraints — Not all SKUs are available in all regions; use GetSkusFabricCapacitiesAsync to check
6. Long provisioning times — Capacity creation can take 5-15 minutes
