C# has a language feature, that can convert method groups to delegate type. So, instead of:

private void Foo() {}
private void Bar(Action arg) {}

Bar(new Action(Foo));

you can write:

Bar(Foo);

I'm not a VB guy, but I suspect, that VB .NET hasn't such feature. Looks like you need AddressOf operator:

New PropertyMetadata(False, AddressOf AutoScrollPropertyChanged)
