.NET 5 CTP Licensing
This .NET 5 version of ComponentOne WPF controls is a CTP (community technology preview). It is not intended to be used in final production. The controls have a built-in license that will expire on January 31, 2021. Three days before this date, applications built using the controls will display a message that the license will expire in three days. And after January 31, 2021, applications will not work.
The .NET 5 controls will be officially released in November 2020. At that time, you will be able to update the version of the controls to a properly licensed version that will not expire.
