 Weakly is a collection of some useful weak-reference types available as portable class library for **net45+win8+wp8+wpa81** and available through nuget.
 
-Normally it is not possible to call private methods using reflection in Windows Phone and Windows Store Apps. You will get a MethodAccessException.
-Weakly solves this problem by using compiled Expressions. So it is not only possible to call private methods but also faster as dynamic invocation.
