Using external DbContext within hook.

[gmullernh]

Hey!
I'm adding a logging mechanism to a Piranha CMS instance.
The ideia is to add an EF Core operation to another database context (that's being properly created) and hooking it on the RegisterOnAfterSave hook.
I'm getting a "Cannot access a disposed object" at the logContext.Logs.Add method.
After some research, found out that it might be being caused by a void method in the stack, that disposes the context before the operation. After some more research, I've found out that the delegates of Piranha's CMS Hook Manager, uses void methods.

Might this the issue?
Any ideias on how to trigger this hook using a Task or a method, without losing the context?

My implementation on the Startup.cs:

public void Configure(
    IApplicationBuilder app,
    IWebHostEnvironment env,
    IApi api,
    LogContext logContext,
    UserResolverService userResolverService) {
    // ...
    App.Init(api);
    // ...
    App.Hooks.Pages.RegisterOnAfterSave((page) => {
        logContext.Logs.Add(new LogChangeModel() {
          Id = page.Id.ToString(),
            Title = page.Title,
            Snapshot = JsonSerializer.Serialize(page),
            User = userResolverService.GetUser(),
            ChangeTime = DateTime.Now
        });
        logContext.Logs.SaveChanges();
      }
      // ...
    }

The problem is that the context you’re using in the hook will be disposed as soon as the Configure method is done, you need to resolve the context inside the hook itself.
