Issue with SAPbobsCOM connection

I am attempting to develop a solution for generating sales orders through a C# MVC application.

I can develop a WinForms application which allows me to create sales orders (using the COM DI 'Order' application from the SDK samples).

When I attempt to port the code to my MVC application, I get error "No SAP licences" when I attempt to connect to my company.

I am using the same company/user account in both the WinForms and MVC applications, so do I need different licence types to get access to my B1 system through the different applications?
