testing csharp uri code

using System;
using System.Collections.Generic;
using System.Net.Http;
using System.Web;
					
public class Program
{
	public static void Main()
	{
		string longurl = "http://somesite.example/news.php?article=1&lang=en";
		var uriBuilder = new UriBuilder(longurl);
		var query = HttpUtility.ParseQueryString(uriBuilder.Query);
		query["action"] = "🤣";
		query["attempts"] = "11";
		query["attempts"] = "12";
		query.Add("attempts", "15");
		query.Add("🤣", "15");
		Console.WriteLine(query.ToString());
		uriBuilder.Query = query.ToString();
		longurl = uriBuilder.ToString();
		Console.WriteLine(longurl);
		
		var queryParams = new List<KeyValuePair<string?, string?>>();
		var content = new FormUrlEncodedContent(queryParams);
		Console.WriteLine(content.ReadAsStringAsync().Result);
		
		var req = new HttpRequestMessage(HttpMethod.Get, "/riot/account/v1/active-shards/by-game/by-puuid?hello=world");
		Console.WriteLine(req.ToString());
		Console.WriteLine(req.RequestUri.ToString());
		
		Uri uri = new Uri(req.RequestUri.ToString(), UriKind.RelativeOrAbsolute);
		Console.WriteLine(uri.ToString());

maybe you could also remove the netcoreapp3.1(End of support: December 13, 2022) and net7.0(End of support: May 14, 2024) and add net8.0

[MingweiSamuel]

Aight sounds good (does adding net8.0 do anything if everything else stays the same?)

Actually I'll do this in a separate commit

adding net8.0 won't change anything but I think it's a good idea to include the latest LTS version of .NET
