ServiceStack: Reinstate pipeline when invoking a Service manually?

Question

As a follow-up to this question, I wanted to understand how my invoking of a Service manually can be improved. This became longer than I wanted, but I feel the background info i

Answer 1

What parts of the pipeline is lost?

None of the request pipeline is executed:

myRequestService.Any(e.Request);

Is physically only invoking the Any C# method of your MyRequestService class, it doesn't (nor cannot) do anything else.

The recommended way for invoking other Services during a Service Request is to use the Service Gateway.

But if you want to invoke a Service outside of a HTTP Request you can use the RPC Gateway for executing non-trusted services as it invokes the full Request Pipeline & converts HTTP Error responses into Typed Error Responses:

HostContext.AppHost.RpcGateway.ExecuteAsync()

For executing internal/trusted Services outside of a Service Request you can use HostContext.AppHost.ExecuteMessage as used by ServiceStack MQ which applies Message Request Request/Response Filters, Service Action Filters & Events.

I have registered with container.AddScoped

Do not use Request Scoped dependencies outside of a HTTP Request, use Singleton if the dependencies are ThreadSafe, otherwise register them as Transient. If you need to pass per-request storage pass them in IRequest.Items.
