Activating a license
To activate a license, follow the steps below:
- In Visual Studio, create a new project or open the code of your existing application. For more information on creating a new project, see the Microsoft documentation(opens in a new tab). It’s recommended to create a project that runs on .NET 6.0 or newer.
- Create a
LicenseManagerobject in the code file where the application loads before using any of the methods of Nutrient .NET SDK (formerly GdPicture.NET). - Pass the license key to the
RegisterKEYmethod of theLicenseManagerobject. - Repeat this process for all the code files where you use Nutrient .NET SDK.
