 ## Dependencies, Refactoring & Documentation
 
 - Migrated code for some loading indicators from the library [LoadingIndicators.WPF] (https://github.com/zeluisping/LoadingIndicators.WPF) to the NETworkManager repo, as the original repo looks unmaintained and has problems with MahApps.Metro version 2 and later.
