Microsoft .NET Framework

HelpMaster is built upon the Microsoft .NET Framework

HelpMaster is developed on the Microsoft .NET technology stack for both the desktop and web portal, and requires that the Microsoft .NET framework v4.7.2 or greater be installed on the machine that any HelpMaster component is running on.

The .NET core hosting platform is also required in order to run the web portal.

For hosting the web portal the .Net Extensibility 4.7 and ASP.Net 4.7 features also need to be deployed along with the Web Server role.
