Hi Phillip,
Thanks for contacting Syncfusion support.
Please find below the response for your queries.
If you are using Syncfusion NuGet packages from nuget.org or assemblies from trial installer, you should generate and register corresponding version and platforms license key in your application, to avoid the trial license warning.
Refer below the KB article to generate license keys for Essential Studio platforms
Also our license keys are version and platform-specific. So, all the referenced Syncfusion assemblies\NuGet packages might be on the same version as license key version.
Let us know, if we misunderstood something.
Regards,
Kalap Johnson Peter P.
