System.Uri does not compact empty path segments as claimed

[spazmodius]

Type of issue

Typo

Description

This document claims that

As part of canonicalization in the constructor for some schemes, dot-segments and empty segments (/./, /../, and //) are compacted (in other words, they are removed). The schemes for which System.Uri compacts segments include http, https, ...

It is not true that empty segments are removed.

I just tested and it works for me. I tested with .NET Framework 4.8, .NET 8, and .NET 9

using System;

namespace MyApp
{
    public class App
    {
        public static void Main(string[] args)
        {
            string uriPath = "http://myUrl/other/../second/././/./hello";
            
            var uri = new Uri(uriPath);

            Console.WriteLine($"Original URI: {uriPath}");
            Console.WriteLine($"AbsoluteUri: {uri.AbsoluteUri}");
            Console.WriteLine($"PathAndQuery: {uri.PathAndQuery}");
        }
    }
}

Output:

Original URI: http://myUrl/other/../second/././/./hello
AbsoluteUri: http://myurl/second//hello
PathAndQuery: /second//hello

Thanks for looking at this, @adegeo . Either I wasn't clear in my issue description, or you didn't fully assess your output, because it validates the issue I meant to describe. Your output still contains un-compacted empty segments.
