Straightforward question is: are Microsoft.Extensions.Options.IOptions meant to be used only within the context of umbrella app (web app in this case) or in class libraries also?
Example:
In a n-layered, asp.net core app we have services layer that is dependant on some settings coming from appsettings.json file.
What we first started with is something along these lines in Startup.cs:
services.Configure<Services.Options.XOptions>(options =>
{
options.OptionProperty1 = Configuration["OptionXSection:OptionXProperty"];
});
And then in service constructor:
ServiceConstructor(IOptions<XOptions> xOptions){}
But that assumes that in our Service layer we have dependecy on Microsoft.Extensions.Options.
We're not sure if this is recomended way or is there some better practice?
It just feels a bit awkward our services class library should be aware of DI container implementation.
