# 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 schedulerC
