You can view the changes made to the default new React Native Windows applications for C++ and C# using React Native Upgrade Helper. See this document for more details.

Starting with React Native Windows 0.82, the legacy Paper architecture has been completely removed. All apps now run exclusively on the New Architecture (Fabric). If you haven't already migrated your app to Fabric, you must do so before upgrading to 0.82. See the New Architecture migration guide for details
