. .NET is a simple intermediary pattern implementation, an in-process messaging mechanism (with no other external dependencies). Supports messaging of requests/responses, commands, queries, notifications, and events in synchronous or asynchronous form, and supports intelligent scheduling of messages through C# generics.
First, create a new asp.net Core 3.1 project.
nuget install:
To register the service, add the following in the ConfigureServices method in the Startup file:
Request/response mode

This mode is actually publishing subscriptions, subscribers do not need to pay attention to who the publisher is, and publishers do not need to pay attention to who the subscribers are.

Create a new InsertDatabase class, and after receiving the message, store the user information into the database with the following code:
We try to send a message from UserInfo through the controller, and the code is as follows:
Try to visit:The hyperlink login is visible., found that both methods received a message from us, as follows:
Reference Documentation:The hyperlink login is visible.
