Multi tenant application using asp mvc .net core 5. I have a ‘Tenant’ type that gets resolved using a custom resolver that uses the httpcontext to get the user’s current tenant. Resolution of this type is required to get a DbContext object (and others down the tree).
I can’t use httpcontext in hangfire so I’d like to be able to resolve this type using a different resolver (pulling the tenant ID from something other than the httpcontext). First thought was to implement a custom activator where I could detect that ‘Tenant’ was request and provide a different implementation. I’ve tried this:
as well as the variation on this page
I couldn’t get those to call the custom activator, a breakpoint in the activator was never hit.
So then I also saw there is a ‘UseActivator’ option in the ‘AddHangfireServer’ service registration, and I tried this:
services.AddHangfireServer(o => o.Activator = new HangfireActivator(services.BuildServiceProvider()));
With that I get a warning to not use ‘BuildServiceProvider’. I am unsure of another way to get a ServiceProvider in ConfigureServices.
But as a larger question, am I pursuing this correctly? It is only the one type, ‘Tenant’, that I need to change the implementation for in Hangfire.
Had anyone else needed to implement a custom resolver for a multi-tenant application for hangfire when you don’t have a HttpContext?
