the part of the csproj for it

<ItemGroup>
        <Reference Include="xTile" HintPath="C:\Program Files (x86)\Steam\steamapps\common\Stardew Valley\xTile.dll" />
    </ItemGroup>

<ItemGroup>
        <Reference Include="xTile" HintPath="C:\Program Files (x86)\Steam\steamapps\common\Stardew Valley\xTile.dll" />
    </ItemGroup>

that dll exists, both in the hintpath and the compiled folders though

System.InvalidOperationException: ... cannot be serialized because it does not have a parameterles..

I'm trying to make an AOT class library, but I am unable to run it once compiled. Here's the bit of code it doesn't like

var parser = new TMXParser();
parser.Export(tmx, tmxpath);

var parser = new TMXParser();
parser.Export(tmx, tmxpath);

and the full error:

❔ [UnmanagedCallersOnly] with a function that takes a string

I'm trying to make a C# library, and had success with

using System.Runtime.InteropServices;

namespace ToasterMap
{
    static class ToasterMap
    {
        [UnmanagedCallersOnly(EntryPoint = "add")]
        public static int Add(int a, int b) => a + b;
    }
}

using System.Runtime.InteropServices;

namespace ToasterMap
{
    static class ToasterMap
    {
        [UnmanagedCallersOnly(EntryPoint = "add")]
        public static int Add(int a, int b) => a + b;
    }
}

but once I made it

using System.Runtime.InteropServices;
using System;

namespace ToasterMap
{
    static class ToasterMap
    {
        public static String tbinPath;

        [UnmanagedCallersOnly(EntryPoint = "add")]
        public static int Add(int a, int b) => a + b;

        [UnmanagedCallersOnly(EntryPoint = "init")]
        public static void Init(string tbinPath)
        {
            if (!File.Exists(tbinPath))
            {
                throw new Exception("TBin path does not exist");
            }

            ToasterMap.tbinPath = tbinPath;
        }
    }
}

using System.Runtime.InteropServices;
using System;

namespace ToasterMap
{
    static class ToasterMap
    {
        public static String tbinPath;

        [UnmanagedCallersOnly(EntryPoint = "add")]
        public static int Add(int a, int b) => a + b;

        [UnmanagedCallersOnly(EntryPoint = "init")]
        public static void Init(string tbinPath)
        {
            if (!File.Exists(tbinPath))
            {
                throw new Exception("TBin path does not exist");
            }

            ToasterMap.tbinPath = tbinPath;
        }
    }
}

It now fails to compile with:

C:\Coding\C#\ToasterMap\ToasterMap.cs(14,33): error CS8894: Cannot use 'string' as a
 parameter type on a method attributed with 'UnmanagedCallersOnly'. [C:\Coding\C#\To
asterMap\ToasterMap.csproj]

C:\Coding\C#\ToasterMap\ToasterMap.cs(14,33): error CS8894: Cannot use 'string' as a
 parameter type on a method attributed with 'UnmanagedCallersOnly'. [C:\Coding\C#\To
asterMap\ToasterMap.csproj]

I understand that it seems I can't use string as a type, but not sure what else to use? char[] and byte[] also fails

❔ C# library usable from python

I was wondering how to do this, and stumbled upon https://stackoverflow.com/a/29854281 which answered the question, but then caused two new ones. 1. can this be done without .NET installed on the user's machine 2. how do I create a project for that in VS? Do I just choose class library or something else?

.lnk parsing

This tool https://github.com/securifybv/ShellLink seems to be decent for parsing/modifying/creating .lnk files, but I can't find/know how you use it, anyone used it/know how to use it? (Or any other options)
