Hi SR,
Thanks for contacting Syncfusion support.
If you are using Syncfusion nuget packages from nuget.org or from trial installer, then you should register the respective product and version license key in your application
Our license keys can be generated from the License & Downloads section of the Syncfusion website.
Refer the below article to know about generating license key,
Find below the details to know about registering license key,
Our license keys are version and platform-specific. Please ensure that all the referenced Syncfusion assemblies\NuGet packages are on the same version as license key’s version.
Also if you’ve upgraded both license key and nuget packages, could you please try cleaning your project, deleting the bin\obj folders and rebuild your application, then check whether it resolves the issue?
If the reported issue is still not resolved, please share us the following details to check issue from our side,
