We have developed an Excel add-in platform which uses below packages:
| - Main.Controls.Wpf.Notification.2.8.1.0 |
| - GMap.NET.WindowsForms.1.7.1 |
| - Extended.Wpf.Toolkit.2.5 |
| - EPPlus.4.0.4 |
We have downloaded them from Codeplex and Syncfusion for free. Are we allowed to use this free packages in our software commercial version or we should purchase the licenses from somewhere?
Any help would be really appreciated.
Thanks
