Originating bug report on the .net core API docs:
dotnet/dotnet-api-docs#2854

To summarize, we start with this method signature:

public static ImmutableArray<TSource> ToImmutableArray<TSource>(this ImmutableArray<TSource>.Builder builder)

Compiler output is

M:System.Collections.Immutable.ImmutableArray.ToImmutableArray``1(System.Collections

A good example is ConfuserEx's anti tamper.
Just loading and saving the file with dnlib will remove the extra section injected by ConfuserEx and the assembly cannot be run or deobfuscated any further.

While reading the code to understand how to use this (or related) library, I found following comment in MonoMod.RuntimeDetour/NativeDetour.cs:
https://github.com/MonoMod/MonoMod/blob/86f3be60825da9328130a639a9a47ba13e49486e/MonoMod.RuntimeDetour/NativeDetour.cs#L18

I didn't find the DetourManager and I think this was meant to be DetourHelper. If so, correcting this would make everything

Are there any plans to implement the reflection system in the project, if so, do you have any idea how it will work to generate methods and classes at runtime, and execute this code?

For exemple, if we have this code:

    static void Main(string[] args)
    {
        const string AssemblyName = "HelloWorld.dll";
        var assembly = AssemblyBuilder.DefineDynamicAssembly(

Many public APIs don't provide any in-editor tooltips. It would be wise to fix them to provide usage context to mod/GSL developers.

When outputting signature of entry point method as CIL assembler code, it should be marked with .entrypoint directive.

Example code:

using System;
using System.Reflection;
using CilBytecodeParser;

class Program
{    
    public static void Main(string[] args)
    {
        Console.WriteLine(CilAnalysis.MethodToText(MethodBase.GetCurrentMethod()));
        Console.ReadKey();
