✅ Opinion time: Handling multiple id's in the same path (ASP.NET MVC)

I want to make surveys and survey submissions. The URL will be something like /surveys/1/submissions/2 indicating that I'm checking the survey with id 1 that has the submission of id 2. There will be CRUD with Entity Framework for both surveys and submissions. Is this a good idea to use two different controllers, or can it be done on a single controller?

Why does the following prints "Point" to the console instead of "(2, 3)"?

Point thing = new Point(2, 3);
System.Console.WriteLine(thing); // prints Point
System.Console.WriteLine(thing.ToString()); // prints (2, 3)

public class Point
{
    public int X {get; private set; }
    public int Y {get; private set; }

    public Point(): this(0, 0)
    {

    }

    public Point(int x, int y)
    {
        this.X = x;
        this.Y = y;
    }

    // using NEW not OVERRIDE
    public new string ToString()
    {
        return $"({X}, {Y})";
    }
}

Point thing = new Point(2, 3);
System.Console.WriteLine(thing); // prints Point
System.Console.WriteLine(thing.ToString()); // prints (2, 3)

public class Point
{
    public int X {get; private set; }
    public int Y {get; private set; }

    public Point(): this(0, 0)
    {

    }

    public Point(int x, int y)
    {
        this.X = x;
        this.Y = y;
    }

    // using NEW not OVERRIDE
    public new string ToString()
    {
        return $"({X}, {Y})";
    }
}

Is it because Console.WriteLine uses an object reference internally?

✅ Recommended way to handle null results from a repository GET action?

I'm learning .NET Core and in Java (yes, I did Java) I used to create custom exceptions to throw. The equivalent would be

var company = _repository.Company.GetCompany(companyId, trackChanges);
if (company is null)
    throw new CompanyNotFoundException(companyId);

var company = _repository.Company.GetCompany(companyId, trackChanges);
if (company is null)
    throw new CompanyNotFoundException(companyId);

Is this a good idea?

❔ Referencing new projects with the main project

Let's say I have a main project CoreProject and I want to add 2 new projects: a LoggerService and a Contracts. The question is: Is it okay if I make LoggerService have a project reference with Contracts and then have CoreProject have a project reference with LoggerService? Does this mean that CoreProject also has a reference with Contracts because LoggerService has it?
