Once you log in to your GeneXus Account with GeneXus Web, your workspace will open and you will see your active Knowledge Bases or, in the case of not having one, you will be able to create a new one:
You have to create a new Knowledge Base (a new GeneXus project). To do so, click on the “+” button.
The New Knowledge Base dialog box will open. You can name the Knowledge Base “TicketReservation,” for example. Also, select the environment you want to use to generate the application programs, as well as the programs required to create and maintain the database. Choose .NET Core Environment.
Click on the OK button to create your Knowledge Base.
