How to implement dynamic feature in .net 3.5

Question

How to implement this behavior in .NET 3.5, where there is no dynamic keyword.

Guid CLSID_ShellApplication = new Guid("13709620-C279-11CE-A49E-444553540000");
Type shellApplicationType = Type.GetTypeFromCLSID(CLSID_ShellApplication, true);
dynamic shellApplication = Activator.CreateInstance(shellApplicationType);
dynamic windows = shellApplication.Windows();

for (int i = 0; i < windows.Count; i++)
    windows.Item(i).Refresh();

I tried using

MethodInfo windowsMethod = shellApplicationType.GetMethod("Windows");

but GetMethod returns null .

If what you want is dynamic behaviour in .NET < 4.0, you can go DLR straight Check this site http://dlr.codeplex.com/ And also you can take a look at this video. The guy behind IronPython shows how to implement a DLR binder for office (which uses COM) http://channel9.msdn.com/blogs/pdc2008/tl10
