The purpose is to showcase three different approaches to how controller and actions are designed.

1. gen1: Service class based controllers. One controller take a dependency on one or more service classes. These controllers are notoriously difficult to deal with once the controllers grow large enough.
2. gen2: The controller takes a dependency on one or more command classes that act as a command and handler.
3. gen3: The controller only utilizes a special dispatcher to send commands. It doesn't care about which handlers are invoked to deal with the command.

Generations of controllers

Prerequisites

• dotnet core 3.1
• MS-SQL database
• Redis

Startup instructions

Connection strings

For anyone new or not used to dotnet, connection strings are simply a means to connect to external services.

All connection strings should be set using the dotnet user-secrets set 'key' 'value'

Keys
SQL server: "ConnectionString:default"
Azure queue: "ConnectionString:queue"
Redis cache: "ConnectionString:cache"

Have a look at the appsettings.json in the WebClient project.

This application is configured to require an MS-SQL database and redis cache. You can easily just pull the docker images for this.
The azure queue storage is optional.

Database tables

1. Go to scripts folder
2. Run the database.sql script on the database you're using

HTTP Requests

I've created a collection of http requests in http-tests/tests.http.
You can run these directly from JetBrains Rider.
