Hello,
I tested two versions:
grandnode2-2.1.0_Source and grandnode2 from Github
litedb

In both cases the plugins are not loaded. If I click the button to update the list of plugins, the application is destroyed.

Accordingly, the application does not implement payment and delivery methods. Is this a bug or marketing? )

Hello,
If you don't see any plugins, it's likely that they were not built. Before starting the application, try rebuilding the solution

Thanks, this helped.

But why do I click "Install" and get: HTTP Error 503.0 - Server is down. After running the application again, I can go into the plugin settings.
If I click the refresh list of plugins button, the application will be destroyed too.

In ASP.NET Core, when the application starts, DLL libraries are loaded into the application's memory. It is not possible to directly load new libraries or inject additional interfaces into Dependency Injection (DI) during the application's runtime. Consequently, when installing, uninstalling, or reloading plugins, an application restart is necessary.

In a local environment using Visual Studio, the application stops, and you need to manually restart the debugging process. In a production environment, when deployed, the application should automatically restart. This behavior is typically in IIS and NGINX server environments

Thanks, this was useful for me.
