Hi, we have a web application that users can take online reports from ou ERP system data... And we have another web application that is used by our teachers and employees.

We can't change the ERP web app because its a closed DLL, in this case we made some extended functionality in our custom internal web app and we are willing to put this functionality on the "menu" of the ERP web app.

I need to integrate the two applications in the following way:

When I click in the menu of the ERP web app, I want that our internal web app assert that the click have come from our ERP web app and not typed in the URL, this is possible?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy.
