@ZZZZZZZZZZZZZZZZZZZZZZZZZ Would it be correct to say webhook is basically a callback for when something happens. And that it only exist for system to system communication? Since end users don't have api endpoints. For real time updates between end users and servers, we should use WebSocket instead.

Reference type variables themselves are stored on the stack, is that correct?
Sorry it was a typo, I meant if we create int variables directly, they are stored on the stack

Also is this why we don't have boxing/unboxing with List<int>, because those ints are stored directly on the heap ( albeit inside the List array )

It sounds like aggregate is just projection

✅ How is aggregate in DDD related to event sourcing and CQRS?
Yep, I understand DDD, CQRS and Event sourcing are separate things. In an event driven architecture with microservices, we often couple event sourcing with CQRS. Where each microservice has its own event store (event sourcing), coupled with separate read model and write model (CQRS) However I'm having a difficulty wrapping my head around where DDD and in particular, aggregates come in. DDD to me is a way of designing microservices. It has 3 layers, application layer ( web api ), domain model layer ( entities, interfaces), infra layer ( repository implementation and efcore).

I keep seeing people talking about aggregate in event sourcing CQRS systems, so I'm really confused

Who handles dependency Injection in a class library?
Think I got this! The code you wrote helped out a lot! Extension method 
public static class ServiceCollectionExtensions {
    // Call this method in the main project
    public static void AddCandidateService(this IServiceCollection services) {
        services
            .AddOptions<DatabaseOptions>()
            .BindConfiguration(DatabaseOptions.SectionName);
        services.AddScoped<IPositionRepository, PositionRepository>();
        services.AddScoped<ICandidateRepository, CandidateRepository>();
        services.AddScoped<ICandidateFactory, CandidateFactory>();
        services.AddScoped<ICandidateCreditService, CandidateCreditServiceClient>();
        services.AddTransient<ITimeProvider, TimeProvider>();
    }
}
public static class ServiceCollectionExtensions {
    // Call this method in the main project
    public static void AddCandidateService(this IServiceCollection services) {
        services
            .AddOptions<DatabaseOptions>()
            .BindConfiguration(DatabaseOptions.SectionName);
        services.AddScoped<IPositionRepository, PositionRepository>();
        services.AddScoped<ICandidateRepository, CandidateRepository>();
        services.AddScoped<ICandidateFactory, CandidateFactory>();
        services.AddScoped<ICandidateCreditService, CandidateCreditServiceClient>();
        services.AddTransient<ITimeProvider, TimeProvider>();
    }
}
This is the DatabaseOptions class 
namespace Refactoring.LegacyService;

public class DatabaseOptions {

    public const string SectionName = "ConnectionStrings";

    public string ApplicationDatabase { get; set; } = string.Empty;
}
namespace Refactoring.LegacyService;

public class DatabaseOptions {

    public const string SectionName = "ConnectionStrings";

    public string ApplicationDatabase { get; set; } = string.Empty;
}
It would be injected into a class like below, eg. in a repository 
    public CandidateRepository(IOptions<DatabaseOptions> options) {
        _connectionString = options.Value.ApplicationDatabase;
    }
    public CandidateRepository(IOptions<DatabaseOptions> options) {
        _connectionString = options.Value.ApplicationDatabase;
    }

Right, the actual project using this library will be configuring the config via ConfigurationBuilder, and we will add the settings files from there. Then we do something like services.Configure<XXXSettings>(Configuration.GetSection("XXXSettings")); And in the class library we can inject IOptions<XXXSettings>

Right, so this appsettings.json is stored in the caller project. But class libraries should be agnostic of such settings, which is why you defined FooOptions.cs right?
