Updating GroupDocs.Comparison from version 20.1 to 20.6, the license still works, but when updating the Aspose libraries(Cells, Email, PDF, Slides, Tasks, Word) to 20.6 the GroupDocs.Comparison licence stops working.
The activation of the license is done in a Global.asax class during application startup for the main application.
The GroupDocs.Comparison and Aspose dependencies are in a .NET standard 2.0 project, referred later as dfs .
The activation of the license could be described as:
Global.asax calls a license activation method in a project containing general business logic. Project calls a method in project dfs. The dfs-method activates the licenses for the GroupDocs.Comparison and Aspose dependencies.
Main Application => Business logic project => dfs => activate groupdocs.comparison; activate Aspose
