❔ [Avalonia] Basic question regarding subclassing

Let's say I have some types like so:

public abstract class Foo {}

public class FooA: Foo {}

public class FooB: Foo
{
  public string Name { get; }
  public int age { get; }
}

public abstract class Foo {}

public class FooA: Foo {}

public class FooB: Foo
{
  public string Name { get; }
  public int age { get; }
}

public abstract class Foo {}

public class FooA: Foo {}

public class FooB: Foo
{
  public string Name { get; }
  public int age { get; }
}

public abstract class Foo {}

public class FooA: Foo {}

public class FooB: Foo
{
  public string Name { get; }
  public int age { get; }
}

I'd like to display a

List<Foo>

List<Foo>

List<Foo>

List<Foo> where

FooA

FooA

FooA

FooAs and

FooB

FooB

FooB

FooBs would be displayed completely differently.

Just as a random example,

FooA

FooA

FooA

FooA would simply display "This is a FooA" with a red background while

FooB

FooB

FooB

FooB would display "This is a FooB with name '...' and age '...' " in a blue background. You get the idea.

The way I envision this is that

FooA

FooA

FooA

FooA and

FooB

FooB

FooB

FooB would themselves define how they should be displayed.

I would be really grateful if someone could break this down to me. Bonus points if there's a working example.
