#ViewModel Creation

In MvvmCross v3 - Hot Tuna - the default ViewModel location and construction was overhauled in order to provide 3 new features:

- constructor based Dependency Injection
- navigation using Typed navigation classes
- saving and reloading VM state for 'tombstoning'

These changes were breaking changes for existing v1 and vNext apps, but provide significant testability and usability advantages for MvvmCross developers.
