Est. Budget: $30.00
I will send you the solution of a simple WPF calculator that has three inputs and one output. Your job will be to restructure the solution in respect to the MVVM (Model-View-ViewModel) design pattern. There is one existing Unit Test that should also be preserved. This shouldn't take very long at all, and I'll also include the original specification in case it is unclear what the app is supposed to do.
