When I create an EXE using Spread9 in a WPF app., all works fine.
When I create a WPF DLL (class assembly) that attempts to use Spread9, I see two problems:
1 The Viz Studio editor does not show Spread9 at design time
2 At run-time I get an error telling me that a ‘License for GcSpreadSheet cannot be found in the program.’ See attached screenshot.
Is it possible to build a DLL that provides a WPF UI that can display Spread9?
