## Generated Code

Simple activities with timeouts extend the `TimeoutAsyncCodeActivity` class, which already contains a Timeout.

```
using ...
namespace MyCompany.MyProduct.Activities
{
    [LocalizedDisplayName(nameof(Resources.Addition_DisplayName))]
    [LocalizedDescription(nameof(Resources.Addition_Description))]
    public class AdditionWithTimeout : TimeoutAsyncCodeActivity
    {
      ...
    }
}
```
