/*
I was curious to see what the maximum number of generic parameters were allowed for a method.
This was inspired by https://www.tabsoverspaces.com/233892-whats-the-maximum-number-of-arguments-for-method-in-csharp-and-in-net

To run this code, make a C# console application with the .csproj file looking like this:

<Project Sdk="Microsoft.NET.Sdk">
	<PropertyGroup>
		<OutputType>Exe</OutputType>
		<TargetFramework>net6.0</TargetFramework>

using BenchmarkDotNet.Attributes;

namespace ConsoleApp3
{
	[MemoryDiagnoser]
	public class FormatQueuedTaskMessage
	{
		[Benchmark]
		[Arguments(3)]
		[Arguments(4)]
