WebHost as a IHostedService

[dbones]

Is it possible to make the Webhost, a HostedService, maybe by removing the HostedServiceExecutor (from its internals), or providing another easy to use mechanism setup and host Http/WebApi/Mvc.

So I can create a IHost, and choose to host WebApi/Mvc as a background service.

the reasoning for this is if we consider the WebApi is an Adaptor (as in Ports/Adaptors) this would be one of possibly others (typically I would also have AMQP consumers for a bus, using something like EasyNetQ or MassTransit) all (consistantly) hosted via IHostedService.

In 2.0 that would be tough, but you should look at the work we've done in 2.1 around GenericHost. It's not all the way there but it's a step towards that for a future version (3.0?).

We have the same requirement, but for Service Fabric to host WebApi, and for that I see we even need a generic ServiceFabricHost.

but it's good to see the GenericWebHost sample, that could be a good start for us to implement it before it's available in future version.

We have ported over to using IHostedService for all non-web roles and it is awesome. It would be nice to kick the Microsoft.AspNetCore.Hosting namespace to the curb there is enough of an impedance mismatch (see: IHostingEnvironment.ContentRootPath) that it's a pain toggling between the two.

This may be eventually a 3.0 feature.
