Mvvmcross 6 is a new version of Mvvmcross using Netstandard2 instead of the obsolete PCL libraries. It is also a complete refactoring of the previous versions. Migrating is not as easy as updating nuget. But to prevent further technical debt, you should migrate as soon as possible.
- Upgrade your PCL projects to netstandard2
- Replace all the calls to Mvx.Log (already available in 5)
- Upgrade all your in-house Mvvmcross 5 plugins to 6
