Incorrect behavior of the [ModuleInitializer]?

Question

I try to use [ModuleInitializer] in .net5 code. My test assembly

namespace TestAssembly
{
    public class Class1
    {
        [ModuleInitializer]
        public static void Init()
        {
            Console.WriteLine("ModuleInitializer");
        }
    }
}

I need the Init() method to be called on the assembly loading. Loading code

byte[] rawAssembly = LoadFile("TestAssembly.dll");
Assembly.Load(rawAssembly);

But the initializer isn't called on loading. Also I tried

Assembly.LoadFrom("TestAssembly.dll");
Assembly.LoadFile("TestAssembly.dll");
AppDomain domain = AppDomain.CurrentDomain;
Assembly assembly = domain.Load(rawAssembly);

The initializer is called after

var t = Type.GetType("TestAssembly.Class1, TestAssembly", AssemblyResolver, TypeResolver, false, true);
var obj = Activator.CreateInstance(t);
        

i.e. on the first use of any type from assembly. Is this normal behavior? Can I achieve a call to the initializer without any additional code on assembly loading?

Answer 1

Here is an explanation on github

A module initializer is executed at, or sometime before, first access to any static field or first invocation of any method defined in the module.
