Making an extension

So currently i'm trying to make an extension. And i can't use it. I don't understand what i am doing wrong.

Code:

using Oxide.Core;
using Oxide.Core.Extensions;namespace Oxide.Ext.MapUtils
{
    public class MapUtilsExtension : Extension
    {
        public override string Name => "MapUtils";
        public override string Author => "me";
        public override VersionNumber Version => new VersionNumber(1, 0, 0);        private Libraries.MapUtils map;        public MapUtilsExtension(ExtensionManager manager) : base(manager)
        {
        }        public override void Load() => Manager.RegisterLibrary("MapUtils", map = new Libraries.MapUtils());
    }
}

Code:

using System;
using System.IO;using Oxide.Core;
using Oxide.Core.Libraries;namespace Oxide.Ext.MapUtils.Libraries
{
    public class MapUtils : Library
    {
        // methods
    }
}

My plugin:

Code:

using Oxide.Core;namespace Oxide.Plugins
{
    [Info("Something", "Something", "0.0.1", ResourceId = 000)]
    [Description("This is what the plugin does")]
    public class Something: RustPlugin
    {
        private Ext.MapUtils.Libraries.MapUtils map = Interface.GetMod().GetLibrary<Ext.MapUtils.Libraries.MapUtils>();        void OnServerInitialized()
        {
                map.SomeMethod();
        }
    }
}

And i get an error:

Code:

[Oxide] 17:55 [Error] Error while compiling Something.cs(10,15): error CS0234: The type or namespace name `MapUtils' does not exist in the namespace `Oxide.Ext'. Are you missing an assembly reference?

What's wrong?

P.S. Yes i copied my extension dll to "Managed" folder. Extension loads fine "[Oxide] 18:46 [Info] Loaded extension MapUtils v1.0.0"

 

Any thoughts?

 

You can use the open-source extension by @Calytic as a starter guide. GitHub - Calytic/Oxide.Ext.Catalyst: Plugin & dependency management extension for the Oxide modding framework.
