# Rent and configure your virtual number using .NET SDK

After searching for a number, rent and configure that number for SMS, Voice or both.

Note:
Before you can get started, you need the following already set up:

- 
- [.NET 7 SDK](https://dotnet.microsoft.com/download) or later and a familiarity with how to create a new app.
- [Your .NET application](/docs/numbers/getting-started/dotnet-sdk/searchavailable) for use with the Numbers API.
- A virtual number you have [confirmed to be available](/docs/numbers/getting-started/dotnet-sdk/searchavailable).


## Rent and configure your virtual number

Open the `Program.cs` from your Search Available Numbers .NET project.

Program.cs
// Use this code to rent and configure a virtual number with the .NET SDK. 
using System.Text.Json;
using Sinch;
using Sinch.Numbers;
using Sinch.Numbers.Available.Rent;
    
var sinch = new SinchClient("YOUR_project_id",
                                  "YOUR_access_key",
                                  "YOUR_access_secret");

var response = await sinch.Numbers.Available.Rent("YOUR_phone_number", new RentActiveNumberRequest() {
    SmsConfiguration = new SmsConfiguration {
        ServicePlanId = "YOUR_service_plan_id",
    },
    VoiceConfiguration = new VoiceConfiguration {
        AppId = "YOUR_app_id"
    }
});

Console.WriteLine(JsonSerializer.Serialize(response, new JsonSerializerOptions() {
    WriteIndented = true
}));
Paste the `Rent and configure a virtual number` code in place of the `search for a virtual number` code in the `Program.cs` file.

### Modify your application

The code provided includes placeholder parameters. You'll need to update the parameters detailed in the following subsections with your values.

#### Initialize the client

Before initializing a client using this SDK, you'll need three pieces of information:

- Your Project ID
- An access key ID
- An access key Secret


These values can be found on the [<b>Access Keys</b>](https://dashboard.sinch.com/settings/access-keys) page of the Sinch Build Dashboard. You can also [create new access key IDs and Secrets](https://community.sinch.com/t5/Conversation-API/How-to-get-your-access-key-for-Conversation-API/ta-p/8120), if required.

Note
If you have trouble accessing the above link, ensure that you have gained access to the [Conversation API](https://dashboard.sinch.com/convapi/overview) by accepting the corresponding terms and conditions.

#### Fill in remaining parameters

Replace following parameter values on your `Program.cs` file:

| Parameter | Your value |
|  --- | --- |
| `YOUR_service_plan_id` | Your [SMS service plan ID](https://dashboard.sinch.com/sms/api/rest)This is only required for SMS configuration. |
| `YOUR_app_id` | The Voice app ID or voice API `key`. Found in the [Sinch Build Dashboard.](https://dashboard.sinch.com/voice/apps) |
| `YOUR_phone_number` | The virtual phone number that you previously searched for and would like to rent. |


1. Save the file.


### Build and run your project

1. Before executing your code, you must first compile your application. Execute the following command:



```shell
dotnet build
```

1. Now you can execute the code. Run the following command:



```shell
dotnet run
```

#### Response

You should get a response similar to this one:


```json

}
```

## Next steps

Send a message to yourself using the SMS API or the Voice API (after setting each up accordingly) to verify that the configuration was successful.

- [Send an SMS message](/docs/sms/getting-started).
- [Make a call](/docs/voice/getting-started/dotnet_sdk/make-phone-call).


## Additional resources

- Explore the [API specification](/docs/numbers/api-reference/numbers) to test more endpoints.
- Follow the number rental process [in the Sinch Build Dashboard](https://dashboard.sinch.com/numbers/buy-numbers) UI rather than through this API.
