# Azure.ResourceManager.DurableTask (.NET)

Management plane SDK for provisioning and managing Azure Durable Task Scheduler resources via Azure Resource Manager.

> **⚠️ Management vs Data Plane**
> - **This SDK (Azure.ResourceManager.DurableTask)**: Create schedulers, task hubs, configure retention policies
> - **Data Plane SDK (Microsoft.DurableTask.Client.AzureManaged)**: Start orchestrations, query instances, send events

## Installation

```bash
dotnet add package Azure.ResourceManager.DurableTask
dotnet add package Azure.Identity
```

**Current Versions**: Stable v1.0.0 (2025-11-03), Preview v1.0.0-beta.1 (2025-04-24)
**API Version**: 2025-11-01

## Environment Variables

```bash
AZURE_SUBSCRIPTION_ID=<your-subscription-id>
AZURE_RESOURCE_GROUP=<your-resource-group>
# For service principal auth (optional)
AZURE_TENANT_ID=<tenant-id>
AZURE_CLIENT_ID=<client-id>
AZURE_CLIENT_SECRET=<client-secret>
```

## Authentication

```csharp
using Azure.Identity;
using Azure.ResourceManager;
using Azure.ResourceManager.DurableTask;

// Always use DefaultAzureCredential
var credential = new DefaultAzureCredential();
var armClient = new ArmClient(credential);

// Get subscription
var subscriptionId = Environment.GetEnvironmentVariable("AZURE_SUBSCRIPTION_ID");
var subscription = armClient.GetSubscriptionResource(
    new ResourceIdentifier($"/subscriptions/{subscriptionId}"));
```

## Resource Hierarchy

```
ArmClient
└── SubscriptionResource
    └── ResourceGroupResource
        └── DurableTaskSchedulerResource
            ├── DurableTaskHubResource
            └── DurableTaskRetentionPolicyResource
```

## Core Workflow

### 1. Create Durable Task Scheduler

```csharp
using Azure.ResourceManager.DurableTask;
using Azure.ResourceManager.DurableTask.Models;

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

// Define scheduler with Dedicated SKU
var schedulerData = new DurableTaskSchedulerData(AzureLocation.EastUS)
{
    Properties = new DurableTaskSchedulerProperties
    {
        Sku = new DurableTaskSchedulerSku(DurableTaskSchedulerSkuName.Dedicated)
        {
            Capacity = 1  // Number of instances
        },
        // Optional: IP allowlist for network security
        IPAllowlist = { "10.0.0.0/24", "192.168.1.0/24" }
    }
};

// Create scheduler (long-running operation)
var schedulerCollection = resourceGroup.Value.GetDurableTaskSchedulers();
var operation = await schedulerCollection.CreateOrUpdateAsync(
    WaitUntil.Completed,
    "my-scheduler",
    schedulerData);

DurableTaskSchedulerResource scheduler = operation.Value;
Console.WriteLine($"Scheduler created: {scheduler.Data.Name}");
Console.WriteLine($"Endpoint: {scheduler.Data.Properties.Endpoint}");
```

### 2. Create Scheduler with Consumption SKU

```csharp
// Consumption SKU (serverless)
var consumptionSchedulerData = new DurableTaskSchedulerData(AzureLocation.EastUS)
{
    Properties = new DurableTaskSchedulerProperties
    {
        Sku = new DurableTaskSchedulerSku(DurableTaskSchedulerSkuName.Consumption)
        // No capacity needed for consumption
    }
};

var operation = await schedulerCollection.CreateOrUpdateAsync(
    WaitUntil.Completed,
    "my-serverless-scheduler",
    consumptionSchedulerData);
```

### 3. Create Task Hub

```csharp
// Task hubs are created under a scheduler
var taskHubData = new DurableTaskHubData
{
    // Properties are optional for basic task hub
};

var taskHubCollection = scheduler.GetDurableTaskHubs();
var hubOperation = await taskHubCollection.CreateOrUpdateAsync(
    WaitUntil.Completed,
    "my-taskhub",
    taskHubData);

DurableTaskHubResource taskHub = hubOperation.Value;
Console.WriteLine($"Task Hub created: {taskHub.Data.Name}");
```

### 4. List Schedulers

```csharp
// List all schedulers in subscription
await foreach (var sched in subscription.GetDurableTaskSchedulersAsync())
{
    Console.WriteLine($"Scheduler: {sched.Data.Name}");
    Console.WriteLine($"  Location: {sched.Data.Location}");
    Console.WriteLine($"  SKU: {sched.Data.Properties.Sku?.Name}");
    Console.WriteLine($"  Endpoint: {sched.Data.Properties.Endpoint}");
}

// List schedulers in resource group
var schedulers = resourceGroup.Value.GetDurableTaskSchedulers();
await foreach (var sched in schedulers.GetAllAsync())
{
    Console.WriteLine($"Scheduler: {sched.Data.Name}");
}
```

### 5. Get Scheduler by Name

```csharp
// Get existing scheduler
var existingScheduler = await schedulerCollection.GetAsync("my-scheduler");
Console.WriteLine($"Found: {existingScheduler.Value.Data.Name}");

// Or use extension method
var schedulerResource = armClient.GetDurableTaskSchedulerResource(
    DurableTaskSchedulerResource.CreateResourceIdentifier(
        subscriptionId,
        "my-resource-group",
        "my-scheduler"));
var scheduler = await schedulerResource.GetAsync();
```

### 6. Update Scheduler

```csharp
// Get current scheduler
var scheduler = await schedulerCollection.GetAsync("my-scheduler");

// Update with new configuration
var updateData = new DurableTaskSchedulerData(scheduler.Value.Data.Location)
{
    Properties = new DurableTaskSchedulerProperties
    {
        Sku = new DurableTaskSchedulerSku(DurableTaskSchedulerSkuName.Dedicated)
        {
            Capacity = 2  // Scale up
        },
        IPAllowlist = { "10.0.0.0/16" }  // Update IP allowlist
    }
};

var updateOperation = await schedulerCollection.CreateOrUpdateAsync(
    WaitUntil.Completed,
    "my-scheduler",
    updateData);
```

### 7. Delete Resources

```csharp
// Delete task hub first
var taskHub = await scheduler.GetDurableTaskHubs().GetAsync("my-taskhub");
await taskHub.Value.DeleteAsync(WaitUntil.Completed);

// Then delete scheduler
await scheduler.DeleteAsync(WaitUntil.Completed);
```

### 8. Manage Retention Policies

```csharp
// Get retention policy collection
var retentionPolicies = scheduler.GetDurableTaskRetentionPolicies();

// Create or update retention policy
var retentionData = new DurableTaskRetentionPolicyData
{
    Properties = new DurableTaskRetentionPolicyProperties
    {
        // Configure retention settings
    }
};

var retentionOperation = await retentionPolicies.CreateOrUpdateAsync(
    WaitUntil.Completed,
    "default",  // Policy name
    retentionData);
```

## Key Types Reference

| Type | Purpose |
|------|---------|
| `ArmClient` | Entry point for all ARM operations |
| `DurableTaskSchedulerResource` | Represents a Durable Task Scheduler |
| `DurableTaskSchedulerCollection` | Collection for scheduler CRUD |
| `DurableTaskSchedulerData` | Scheduler creation/update payload |
| `DurableTaskSchedulerProperties` | Scheduler configuration (SKU, IPAllowlist) |
| `DurableTaskSchedulerSku` | SKU configuration (Name, Capacity, RedundancyState) |
| `DurableTaskSchedulerSkuName` | SKU options: `Dedicated`, `Consumption` |
| `DurableTaskHubResource` | Represents a Task Hub |
| `DurableTaskHubCollection` | Collection for task hub CRUD |
| `DurableTaskHubData` | Task hub creation payload |
| `DurableTaskRetentionPolicyResource` | Retention policy management |
| `DurableTaskRetentionPolicyData` | Retention policy configuration |
| `DurableTaskExtensions` | Extension methods for ARM client |

## SKU Options

| SKU | Description | Use Case |
|-----|-------------|----------|
| `Dedicated` | Fixed capacity with configurable instances | Production workloads, predictable performance |
| `Consumption` | Serverless, auto-scaling | Development, variable workloads |

## Extension Methods

The SDK provides extension methods on `SubscriptionResource` and `ResourceGroupResource`:

```csharp
// On SubscriptionResource
subscription.GetDurableTaskSchedulers();           // List all in subscription
subscription.GetDurableTaskSchedulersAsync();      // Async enumerable

// On ResourceGroupResource  
resourceGroup.GetDurableTaskSchedulers();          // Get collection
resourceGroup.GetDurableTaskSchedulerAsync(name);  // Get by name

// On ArmClient
armClient.GetDurableTaskSchedulerResource(id);     // Get by resource ID
armClient.GetDurableTaskHubResource(id);           // Get task hub by ID
```

## 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. **Always use `DefaultAzureCredential`** — never hardcode keys
4. **Handle `RequestFailedException`** for ARM API errors
5. **Use `CreateOrUpdateAsync`** for idempotent operations
6. **Delete task hubs before schedulers** — schedulers with task hubs cannot be deleted
7. **Use IP allowlists** for network security in production

## Error Handling

```csharp
using Azure;

try
{
    var operation = await schedulerCollection.CreateOrUpdateAsync(
        WaitUntil.Completed, schedulerName, schedulerData);
}
catch (RequestFailedException ex) when (ex.Status == 409)
{
    Console.WriteLine("Scheduler already exists");
}
catch (RequestFailedException ex) when (ex.Status == 404)
{
    Console.WriteLine("Resource group not found");
}
catch (RequestFailedException ex)
{
    Console.WriteLine($"ARM Error: {ex.Status} - {ex.ErrorCode}: {ex.Message}");
}
```

## Complete Example

```csharp
using Azure;
using Azure.Identity;
using Azure.ResourceManager;
using Azure.ResourceManager.DurableTask;
using Azure.ResourceManager.DurableTask.Models;
using Azure.ResourceManager.Resources;

// Setup
var credential = new DefaultAzureCredential();
var armClient = new ArmClient(credential);

var subscriptionId = Environment.GetEnvironmentVariable("AZURE_SUBSCRIPTION_ID")!;
var resourceGroupName = Environment.GetEnvironmentVariable("AZURE_RESOURCE_GROUP")!;

var subscription = armClient.GetSubscriptionResource(
    new ResourceIdentifier($"/subscriptions/{subscriptionId}"));
var resourceGroup = await subscription.GetResourceGroupAsync(resourceGroupName);

// Create scheduler
var schedulerData = new DurableTaskSchedulerData(AzureLocation.EastUS)
{
    Properties = new DurableTaskSchedulerProperties
    {
        Sku = new DurableTaskSchedulerSku(DurableTaskSchedulerSkuName.Dedicated)
        {
            Capacity = 1
        }
    }
};

var schedulerCollection = resourceGroup.Value.GetDurableTaskSchedulers();
var schedulerOp = await schedulerCollection.CreateOrUpdateAsync(
    WaitUntil.Completed, "my-scheduler", schedulerData);
var scheduler = schedulerOp.Value;

Console.WriteLine($"Scheduler endpoint: {scheduler.Data.Properties.Endpoint}");

// Create task hub
var taskHubData = new DurableTaskHubData();
var taskHubOp = await scheduler.GetDurableTaskHubs().CreateOrUpdateAsync(
    WaitUntil.Completed, "my-taskhub", taskHubData);
var taskHub = taskHubOp.Value;

Console.WriteLine($"Task Hub: {taskHub.Data.Name}");

// Cleanup
await taskHub.DeleteAsync(WaitUntil.Completed);
await scheduler.DeleteAsync(WaitUntil.Completed);
```
