Describe the bug

Orchard Core version

Add the version of the Orchard Core NuGet packages you use, or the commit hash if you can reproduce this with the source code.
use 2.0.2

To Reproduce

Steps to reproduce the behavior:

1. create new aliyun sms module use orchardcore.sms 2.0.2
2. in Startup.cs add new WorkflowsStartup
   `
   [RequireFeatures("OrchardCore.Workflows")]
   public sealed class WorkflowsStartup : StartupBase
   {
   public override void ConfigureServices(IServiceCollection services)
   {
   services.AddActivity<AliyunSmsTask, AliyunSmsTaskDisplayDriver>();
   }

}
`
4. When the breakpoint is tracked, the inside does not take effect。
services.AddActivity<AliyunSmsTask, AliyunSmsTaskDisplayDriver>();

I don't know what this is? When I put services.AddActivity<AliyunSmsTask, AliyunSmsTaskDisplayDriver>(); on
`
public override void ConfigureServices(IServiceCollection services)
{

services.AddSmsProvider<AliyunSmsProvider>("Aliyun");
services.AddSmsProviderOptionsConfiguration<AliyunProviderOptionsConfigurations>()
    .AddSiteDisplayDriver<AliyunSettingsDisplayDriver>();
services.AddNavigationProvider<AdminMenu>();
services.AddActivity<AliyunSmsTask, AliyunSmsTaskDisplayDriver>();

}
`
it is ok
