### Subscribe to Configuration Keys (Alpha)
```csharp
var client = new DaprClientBuilder().Build();

// The Subscribe Configuration API returns a wrapper around an IAsyncEnumerable<IEnumerable<ConfigurationItem>>.
// Iterate through it by accessing its Source in a foreach loop. The loop will end when the stream is severed
// or if the cancellation token is cancelled.
var subscribeConfigurationResponse = await daprClient.SubscribeConfiguration(store, keys, metadata, cts.Token);
await foreach (var items in subscribeConfigurationResponse.Source.WithCancellation(cts.Token))
{
foreach (var item in items)
{
Console.WriteLine($"{item.Key} -> {item.Value}")
}
}
```
