.NET different descriptions for system.type class? [closed]

I found these two links to a description of System.Type:

• .NET Standard 1.6

• .NET 10

These descriptions list different members. For example:

• The .NET Standard version has a Name property, but the .NET 10 version doesn't.

• The .NET 10 version has a FullName property, but the .NET Standard version doesn't.

Interestingly, I can access both properties:

List<int> l = [];
Type g = l.GetType();
Console.WriteLine($"Name:{g.Name}\nFullName: {g.FullName}");
Console.WriteLine("Generic arguments:");
Console.WriteLine($"Generic type: {g.GetGenericArguments()[0].Name}");

When I read the description for .NET 10 only, I wouldn't know that a Name property exists.

Can someone please explain what the different class descriptions mean? I run Windows 11.
