I am currently writing my first TDD application. The project is in Xamarin.Forms and tested in xUnit.
I am wondering if maybe more experienced developers will have any comments or suggestions regarding the code or architecture, before I will continue with next View Models, to avoid corrections.
I am using also Autofac and Moq.
