ListAsync() on ICriteria

[galvin1234]

Hi, I came across a situation where I need to do ListAsync() on ICriteria, and the Method execution goes to endless,
I just would like to understand what the below method does, or where is the implementation of createInstanceMethod() method, i didn't find any reference of it. In My Case the value of createInstanceMethod variable is coming like as below image,

File Path : \nhibernate-core-5.3.8\src\NHibernate\Bytecode\Lightweight\ReflectionOptimizer.cs

public virtual object CreateInstance()
	{
		return createInstanceMethod != null ? createInstanceMethod() : null;
	}

It is a dynamic method implemented a few lines below:

nhibernate-core/src/NHibernate/Bytecode/Lightweight/ReflectionOptimizer.cs

Lines 86 to 124 in 204b33b

	protected virtual CreateInstanceInvoker CreateCreateInstanceMethod(System.Type type)
	{
	if (type.IsInterface || type.IsAbstract)
	{
	return null;
	}
	var method = new DynamicMethod(string.Empty, typeof (object), null, type, true);
	ILGenerator il = method.GetILGenerator();
	if (type.IsValueType)
	{
	LocalBuilder tmpLocal = il.DeclareLocal(type);
	il.Emit(OpCodes.Ldloca, tmpLocal);
	il.Emit(OpCodes.Initobj, type);
	il.Emit(OpCodes.Ldloc, tmpLocal);
	il.Emit(OpCodes.Box, type);
	il.Emit(OpCodes.Ret);
	return (CreateInstanceInvoker)method.CreateDelegate(typeof(CreateInstanceInvoker));
	}
	else
	{
	ConstructorInfo constructor = ReflectHelper.GetDefaultConstructor(type);
	if (constructor != null)
	{
	il.Emit(OpCodes.Newobj, constructor);
	il.Emit(OpCodes.Ret);
	return (CreateInstanceInvoker) method.CreateDelegate(typeof (CreateInstanceInvoker));
	}
	else
	{
	ThrowExceptionForNoDefaultCtor(type);
	}
	}
	return null;
	}

It generates a following code:

() => new <Type>()
