Hi Gerald, 

Thanks for contacting Syncfusion support. 

Our License Manager utility is used to register the Syncfusion unlock keys alone. Refer the following KB article to find the difference between Syncfusion “Unlock Key” and “License Key” 

https://www.syncfusion.com/kb/8950/difference-between-the-unlock-key-and-licensing-key 

It seems you are using Syncfusion NuGet packages from nuget.org. 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 the following documentation link to know more about licensing. https://help.syncfusion.com/common/essential-studio/licensing/license-key 

  
 

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. 
 
Find below the knowledge base article to know about which version license key should use in application,https://www.syncfusion.com/kb/8951/which-version-syncfusion-license-key-should-i-use-in-my-application  
 
Refer below the documentation for license key generation and registration.

To register the license key: https://help.syncfusion.com/common/essential-studio/licensing/license-key#how-to-register-the-syncfusion-license-key

I may have used the wrong term: the licensing management code I meant to reference is a function called in the App.xaml.cs file and registers a license key, which I generated.

I am well aware of the difference between the Licence Key and the Unlock Key: I generated a License key for version 18.4.0.39, which is what I installed. I am currently using SfChart (or rather, trying to) on Android and UWP and will be using it on iOS at a later time. I followed your documentation to install the License Key in App.xaml.cs as below:

SyncfusionLicenseProvider.RegisterLicense( "MzkzMjczQD.......tTekpzbGJXdDg9" ); // Long license key summarized

and then attempted to run a simple test chart in UWP and was advised that "...version 18.4.0.41 is not found". I am using the latest supported version, 18.4.0.39; 18.4.0.41 appears to be a daily build.

So, what next?

Regards,

Gary

I was able to resolve my issue...I had not noticed that the NuGet Package Manager had installed the wrong version of the software. After removing the errant version and installing the correct one, I did a clean build and the issue was resolved.Thank you for your assistance
