MvvmCross: IMvxLocationWatcher is not resolvable in 3.0.13

Question

I just upgrade my solution from 3.0.9 to 3.0.13. All seems to work well. Much thanks to the MvvmCross team for their continued effort on this great framework.

I am running into a slight problem replacing the now depreciated IMvxGeoLocationWatcher with IMvxLocationWatcher. These services that rely on constructor injection to get an instance of IMvxLocationWatcher are now throwing System.TypeLoadException as shown below:

 System.TypeLoadException: Could not load type 'MyApp.Core.ViewModels.ProgressListViewModel' from assembly 'MyApp.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

What am I missing?

Thanks again.

I just tested with https://github.com/MvvmCross/NPlus1DaysOfMvvmCross/tree/master/N-08-Location

It updated and loads fine.

A TypeLoadException suggests that perhaps you have a mixture of Assembly versions present. Ensure everything = core and UI - is updated to 3.0.13 and that everything is rebuilt. If that fails, then try using Reflector (or similar) in order to analyse what is wrong with your built assemblies.
