Hi Salvatore,
Thanks for contacting Syncfusion support.
We suspect that you are using unlock key instead of license key in your project. Our license keys are different from the unlock keys. Refer below the documentation for more details.
Also
our license keys are version and platform specific. If you are using Syncfusion
NuGet packages from nuget.org or trial installer
, you should generate and register corresponding version and platform license key in your application to prevent the trial water mark
. Refer the following documentation link to know more about licensing.
https://help.syncfusion.com/common/essential-studio/licensing/license-key
Also ensure that all the referenced Syncfusion assemblies\NuGet packages are on same version.
Find below the knowledge base article to know about which version license key should use in application,
If still the issue persist, please share us the following details to check the reported issue.
1. License key registered in your application
2. List of Syncfusion assemblies/NuGet packages used
3. Screenshot of the application with error.
Regards,
Kalap Johnson Peter P.
