## Prerequisites
- An Azure account with an active subscription. [Create an account for free](https://azure.microsoft.com/pricing/purchase-options/azure-account?cid=msft_learn).
- The latest version [.NET Core SDK](https://dotnet.microsoft.com/download/dotnet-core) for your operating system.
- Get the latest version of the [.NET Identity SDK](/dotnet/api/azure.identity).
- Get the latest version of the [.NET Management SDK](../../../concepts/sdk-options.md).
## Install the SDK
First, include the Communication Services Management SDK in your C# project:
```csharp
using Azure.ResourceManager.Communication;
```
## Subscription ID
You need to know the ID of your Azure subscription. Acquire your ID from the portal:
1. Sign in into your Azure account.
2. Select **Subscriptions** in the left sidebar.
3. Select whichever subscription is needed.
4. Click on **Overview**.
5. Select your Subscription ID.
In this example, we assume that you stored the subscription ID in an environment variable called `AZURE_SUBSCRIPTION_ID`.
## Authentication
To communicate with Domain resource, you must first authenticate yourself to Azure.
### 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, you only need to create one top-level `ArmClient`.
To authenticate to Azure and create an `ArmClient`, run the following code:
```csharp
using System;
using System.Threading.Tasks;
using Azure;
using Azure.Core;
using Azure.Identity;
using Azure.ResourceManager;
using Azure.ResourceManager.Communication;
using Azure.ResourceManager.Communication.Models;
using Azure.ResourceManager.Resources;
...
// get your azure access token, for more details of how Azure SDK get your access token, please refer to https://learn.microsoft.com/dotnet/azure/sdk/authentication?tabs=command-line
TokenCredential cred = new DefaultAzureCredential();
// authenticate your client
ArmClient client = new ArmClient(cred);
```
## Interacting with Azure resources
For each of the following examples, we assign our Domain resources to an existing Email communication service.
If you need to create an Email Communication Service, use the [Azure portal](../../../../communication-services/quickstarts/email/create-email-communication-resource.md).
## Create a Domain resource
When creating a Domain resource, you need to specify the resource group name, Email Communication Service name, resource name, and DomainManagement.
> [!NOTE]
> The `Location` property is always `global`.
```csharp
// this example assumes you already have this EmailServiceResource created on azure
// for more information of creating EmailServiceResource, please refer to the document of EmailServiceResource
string subscriptionId = "aaaa0a0a-bb1b-cc2c-dd3d-eeeeee4e4e4e";
string resourceGroupName = "MyResourceGroup";
string emailServiceName = "MyEmailServiceResource";
ResourceIdentifier emailServiceResourceId = EmailServiceResource.CreateResourceIdentifier(subscriptionId, resourceGroupName, emailServiceName);
EmailServiceResource emailServiceResource = client.GetEmailServiceResource(emailServiceResourceId);
// get the collection of this CommunicationDomainResource
CommunicationDomainResourceCollection collection = emailServiceResource.GetCommunicationDomainResources();
// invoke the operation
string domainName = "AzureManagedDomain";
CommunicationDomainResourceData data = new CommunicationDomainResourceData(new AzureLocation("Global"))
{
DomainManagement = DomainManagement.AzureManaged,
};
ArmOperation<CommunicationDomainResource> lro = await collection.CreateOrUpdateAsync(WaitUntil.Completed, domainName, data);
CommunicationDomainResource result = lro.Value;
// the variable result is a resource, you could call other operations on this instance as well
// but just for demo, we get its data from this resource instance
CommunicationDomainResourceData resourceData = result.Data;
// for demo we just print out the id
Console.WriteLine($"Succeeded on id: {resourceData.Id}");
```
## Manage your Domain Resources
### Update a Domain resource
```csharp
...
// this example assumes you already have this CommunicationDomainResource created on azure
// for more information of creating CommunicationDomainResource, please refer to the document of CommunicationDomainResource
string subscriptionId = "aaaa0a0a-bb1b-cc2c-dd3d-eeeeee4e4e4e";
string resourceGroupName = "MyResourceGroup";
string emailServiceName = "MyEmailServiceResource";
string domainName = "AzureManagedDomain";
ResourceIdentifier communicationDomainResourceId = CommunicationDomainResource.CreateResourceIdentifier(subscriptionId, resourceGroupName, emailServiceName, domainName);
CommunicationDomainResource communicationDomainResource = client.GetCommunicationDomainResource(communicationDomainResourceId);
// invoke the operation
CommunicationDomainResourcePatch patch = new CommunicationDomainResourcePatch()
{
Tags =
{
["newTag"] = "newVal",
},
};
ArmOperation<CommunicationDomainResource> lro = await communicationDomainResource.UpdateAsync(WaitUntil.Completed, patch);
CommunicationDomainResource result = lro.Value;
// the variable result is a resource, you could call other operations on this instance as well
// but just for demo, we get its data from this resource instance
CommunicationDomainResourceData resourceData = result.Data;
// for demo we just print out the id
Console.WriteLine($"Succeeded on id: {resourceData.Id}");
```
### List by Email Service
```csharp
// this example assumes you already have this EmailServiceResource created on azure
// for more information of creating EmailServiceResource, please refer to the document of EmailServiceResource
string subscriptionId = "aaaa0a0a-bb1b-cc2c-dd3d-eeeeee4e4e4e";
string resourceGroupName = "MyResourceGroup";
string emailServiceName = "MyEmailServiceResource";
ResourceIdentifier emailServiceResourceId = EmailServiceResource.CreateResourceIdentifier(subscriptionId, resourceGroupName, emailServiceName);
EmailServiceResource emailServiceResource = client.GetEmailServiceResource(emailServiceResourceId);
// get the collection of this CommunicationDomainResource
CommunicationDomainResourceCollection collection = emailServiceResource.GetCommunicationDomainResources();
// invoke the operation and iterate over the result
await foreach (CommunicationDomainResource item in collection.GetAllAsync())
{
// the variable item is a resource, you could call other operations on this instance as well
// but just for demo, we get its data from this resource instance
CommunicationDomainResourceData resourceData = item.Data;
// for demo we just print out the id
Console.WriteLine($"Succeeded on id: {resourceData.Id}");
}
Console.WriteLine($"Succeeded");
```
### Get Domain resource
```csharp
// this example assumes you already have this EmailServiceResource created on azure
// for more information of creating EmailServiceResource, please refer to the document of EmailServiceResource
string subscriptionId = "aaaa0a0a-bb1b-cc2c-dd3d-eeeeee4e4e4e";
string resourceGroupName = "MyResourceGroup";
string emailServiceName = "MyEmailServiceResource";
ResourceIdentifier emailServiceResourceId = EmailServiceResource.CreateResourceIdentifier(subscriptionId, resourceGroupName, emailServiceName);
EmailServiceResource emailServiceResource = client.GetEmailServiceResource(emailServiceResourceId);
// get the collection of this CommunicationDomainResource
CommunicationDomainResourceCollection collection = emailServiceResource.GetCommunicationDomainResources();
// invoke the operation
string domainName = "AzureManagedDomain";
bool result = await collection.ExistsAsync(domainName);
Console.WriteLine($"Succeeded: {result}");
```
## Clean up a Domain resource
```csharp
// this example assumes you already have this CommunicationDomainResource created on azure
// for more information of creating CommunicationDomainResource, please refer to the document of CommunicationDomainResource
string subscriptionId = "aaaa0a0a-bb1b-cc2c-dd3d-eeeeee4e4e4e";
string resourceGroupName = "MyResourceGroup";
string emailServiceName = "MyEmailServiceResource";
string domainName = "AzureManagedDomain";
ResourceIdentifier communicationDomainResourceId = CommunicationDomainResource.CreateResourceIdentifier(subscriptionId, resourceGroupName, emailServiceName, domainName);
CommunicationDomainResource communicationDomainResource = client.GetCommunicationDomainResource(communicationDomainResourceId);
// invoke the operation
await communicationDomainResource.DeleteAsync(WaitUntil.Completed);
Console.WriteLine($"Succeeded");
```
> [!NOTE]
> Resource deletion is **permanent** and no data, including Event Grid filters, phone numbers, or other data tied to your resource, can be recovered if you delete the resource.
