public static void AddLicenseData( string licenseKey, string owner )
Public Shared Sub AddLicenseData ( licenseKey As String, owner As String )
We recommend to add all license data at the start of your application. It is not recommended to call this method each time before you create a PdfDocument instance.
In classic ASP.NET apps we recommended to add license data in Global.asax.cs. In ASP.NET Core apps we recommend to use Startup.cs for the same.
