ISSUES

1. [New issue] UnboundName on invoking member for DynamicObject
http://ironpython.codeplex.com/workitem/35679
User domtop has proposed the issue:

"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..."-----------------

2. [New issue] Fail to display WPF window containing TreeView by Python script
http://ironpython.codeplex.com/workitem/35681
User syang has proposed the issue:

"IronPython 2.7.4 is used.  When a Python script to display a TreeView in a WPF window by calling the method ShowDialog, it could not display the window with Error message "Cannot access Freezable 'System.Windows.Media.SolidColorBrush' across threads because it cannot be frozen".  ScriptSource.Execute(ScriptScope) is called to execute the Python script.  How does method Execute() handle access of WPF UI Thread?"
