v3 02 10 Tip Calculator A recap

Over the course of these articles, we've covered the complete Tip Calc app on 5 platforms from one shared PCL code library using Mvvm.

I hope this was simple and easy to follow...

Just to recap what we did:

• For the core PCL library, we:
• created a Profile 104 library
• added some MvvmCross PCL libraries
• added our services - the Calculator
• added our TipViewModel which exposed properties
• added our App which wired the services together and defined an IMvxAppStart
• For each platform, we generally went through a process like:
• created a platform specific project
• added some MvvmCross PCL libraries
• added some MvvmCross platform specific libraries
• added a Setup class which would initialise everything
• modified the platform-specific Application to call Setup
• created a Views folder
• added a platform specific View
• changed that View base class to something beginning with Mvx
• added a public new TipViewModel ViewModel to link the View to the ViewModel
• modified the XML for that View to add the UI fields
• modified those UI fields to add databinding to the ViewModel properties
• pressed 'Run' :)
• considered some ways that the UI could be improved using platform-specific UI techniques

Generally, these same steps are what you'll follow for each MvvmCross application you want to make.

We'll cover more advanced topics in future articles.
