IOptionsSnapshot is not working with non API/Web scenarios

[cilerler]

It looks like IOptionsSnapshot with reloadOnChange: true set on HostBuilder is not updating the options value when the appsettings.json content changes.

This behavior works fine on WebHost. As far as my understanding IOptionsSnapshot gets generated as Scoped in WebHost for each call. However this doesn't apply to HostBuilder since there is no outside caller exist.

We should be able to detect setting changes and I would like you to consider this issue as a feature request.

Thanks in advance

So your scenario has no concept of scope? You should just use IOptionsMonitor.CurrentValue then

@HaoK Correct but I really don't think it is the best practice to split IOptions, IOptionsSnapshots, IOptionsMonitor for different kind of scenarios. I wish we had only one IOptions service and it decides what to do based on its DependencyInjection registration.

e.g:
I have 2 projects, Console and WebApi they both need to call the same service but because of the Options parameter difference I have to create same service twice.

These projects have completely jagged versions of dependencies

@davidfowl they should be latest now, and comment on below?

This behavior is by design
