I added a parameterless constructor, please try again with v0.3.1, thanks.

This morning I downloaded the source code locally and added constructors to solve the JSON problem, but I found the following two problems：

Subscription messages will fail if you do not inherit ITransientDependency
The constructor I use to pass the message is

new CreateEmailNotificationEto(
                    CurrentTenant.Id,
                    userId,
                    "标题",
                    body)

Without the userId, I wonder if the two constructors have the same number of arguments?

Please check your module dependency.

NotificationService/providers/Mailing/EasyAbp.NotificationService.Provider.Mailing/EasyAbp/NotificationService/Provider/Mailing/NotificationServiceProviderMailingModule.cs

Lines 17 to 22 in a47f1b5

 public override void ConfigureServices(ServiceConfigurationContext context) 

 { 

 context.Services 

 .TryAddTransient<IDistributedEventHandler<CreateEmailNotificationEto>, 

 CreateEmailNotificationEventHandler>(); 

 }

I am using the 0.3.1 package directly now, and still can't receive messages. The error message is as follows

To avoid this exception, either register a component to provide the service, check for service registration using IsRegistered(), or use the ResolveOptional() method to resolve an optional dependency.

Sorry, I read the documentation, but I still don't understand why. I knew I needed to introduce modules, so I did:

I don't think the TryAddTransient below needs to be added to my module either, but I tried it and it doesn't work either. Thank you for your help

Could you please try this code:

            context.Services.AddTransient<CreateEmailNotificationEventHandler>();

Very good. After adding this sentence, emails can be sent normally, and parameters can also be passed normally. I hope it can be added to the document, so that other people will not encounter this problem

There is another problem. I didn't mention a new issue. I just wrote it here.
I used SMS to send the notification, but after execution, the database notification table saved the data, but did not save the passed parameters:
