Cannot add to a c++cli collections::generic::list

I made a simple tree class like this:

public ref class SimpleTreeNode {
public:
    String^ Data;
    List<SimpleTreeNode^>^ Children = gcnew List<SimpleTreeNode^>;
}

however, when i go and try to add stuff like this:

auto^ nstn = gcnew SimpleTreeNode();
nstn->Children->Add(gcnew SimpleTreeNode());

it says "Error: function "System::collections::generic::List::Add [with T=SimpleTreeNode^]" cannot be called with the given argument list

argument types are: (SimpleTreeNode^) object type is: System::Collections::Generic::List^"

what am I missing here? This should work, no?

For your case you should use keyword auto without the hat for both ref and value types. Like this:

auto nstn = gcnew SimpleTreeNode();
auto cN = nstn->Children->Count;

nstn->Children->Add(gcnew SimpleTreeNode());
auto cN2 = nstn->Children->Count;
