3. Step 1. Use MVVM

4. MvvmCross is the way
1.Crossplatform
2.Lots of components baked in
3.Proven solution
4.Extendable and opensource
5.Crossplatform glue between view and
viewmodels

5. Step 2. Reuse the code
1. PCL
2.Solution structure
3.App structure

6. Use PCL
• Lots of 3rd party components (nuget)
• Flexibility
• One place
• Less efforts to maintain code

7. Proven solution structure
• App.Core project (Shared code)
• App.Android project (sometimes App.Droid)
• App.iOS project
• App.OtherPlatform projects

8. Mvx app structure
• Components
• Startup
• Navigation
• Presentation layer

9. App.cs code

10. MvxSetup.cs

11. AppDelegate.cs

12. Maximize shared code
Top reused things in crossplatform applications:
• Icon
