How to read IConfigureOptions of services in Net Core 6-CodePudding

I have two very similar projects, before me first project was working fine, but other after my minor changing project lost correct working. I have understand that after my changing additionally I need to configure manually some options for AddRazorPages services.
Maybe this is not enough and there are other options changing after my changing.
At common I see a lot of various options in my project.
I want to print all of them for comparing and verification before and after my changing for understanding reason of lost correct working.
This is a list of option I see in my project.

How is possible to see/print all of this options?

CodePudding user response：

Try to get a list of configured option types by iterating the IServiceCollection instance:

var configuredOptionTypes =
    from descriptor in builder.Services
    let serviceType = descriptor.ServiceType
    where serviceType.IsGenericType
    where serviceType.GetGenericTypeDefinition() == typeof(IConfigureNamedOptions<>)
    let optionType = serviceType.GetGenericArguments()[0]
    select optionType;
