UnboundName on invoking member for DynamicObject

[ironpythonbot]

Using IronPython 2.7.4 (nuget)

I create a very simple class derived from DynamicObject and set the breakpoint
in TryInvokeMember

public class TestProxy : DynamicObject

{
    public override bool TryInvokeMember(InvokeMemberBinder binder, object[] args, out object result)
    {
        return base.TryInvokeMember(binder, args, out result);
    }
}

I create a script scope and do scope.SetVariable("test", new TestProxy());

Then I execute the string test.Something() and expected to hit the breakpoint.
However it seems that IronPython considers Something is an attribute and call
TryGetMember. If test is a regular C# object, everything works as usual so it
seems to have difficulty with DynamicObject.

As I have been using DynamicObject to create proxies, I cannot use it in a
hosted ironpython session...

As far as I know, IronPython always uses TryGetMember, and then tries to invoke what it gets there. This is according to the python semantics, where member access and calling are two separate steps.

Maybe you can appropriately override TryGetMember to support your use case?
