InvalidOperationException: Unable to resolve service for type 'AspNetCore.IpFiltering.IIpFilteringOptions' while attempting to activate 'AspNetCore.IpFiltering.IpFilteringMiddleware'.

I tried to run the samples from this repo or to install the Nuget and to call to all that you explained in the Read.me -always the same result - it pass build but when I execute the program: an error with this message:
InvalidOperationException: Unable to resolve service for type 'AspNetCore.IpFiltering.IIpFilteringOptions' while attempting to activate 'AspNetCore.IpFiltering.IpFilteringMiddleware'.

on line builder.Run(); of Main(string[] args) at Program.cs

Unbelievable... 2 days, hundreds of pages of information, and few unperfect workarounds later... I found the problem:

there is a bug in AspNetCore.IpFiltering/src/AspNetCore.IpFiltering/ServiceCollectionExtensions.cs
line 29: serviceCollection.AddSingleton /< IpFilteringOptions /> (options);

it should be :
serviceCollection.AddSingleton /< IIpFilteringOptions /> (options);
All other singletons are interfaces, only this one is a class. You can introduce it as a Scope (AddScope), but then it will not see the configurations from the appconfig. Adding this single "I" resolve the problem and samples also start to work.
