 Previously all C# API's were synchronous and thus blocking by nature.
 
 ```csharp
-  // Fluent API example
-  order.AddProduct(productRef, 1)

 ### New behavior
 All API's are now asynchronous and thus are suffixed with Async and return a Task<T> result
 
-  // Fluent API example
-  await order.AddProductAsync(productRef, 1)
-    .SetPaymentMethodAsync(paymentMethodId)
-    .SetShippingMethodAsync(shippingMethodId);
-  
-  // Service method examples
-  await orderService.SaveOrderAsync(order);
-  await emailTemplateService.SendEmailAsync(emailTemplateId, order);

-  // Notification events
-  public class MyNotification : NotificationEventHandlerBase<OrderFinalizedNotification>
