Licence

Hello,

I'd like to understand why, when I update the Nuget extensions in my WPF application, I also have to change the license.

Thank you.

Hi Farid,


Syncfusion license keys are major version and product specific. If you use Syncfusion assemblies, NuGet packages, or scripts from the nuget.org, NPM, CDN, or if you're upgrading from one version to another, such as from v29.* to v30.* you should generate and register the corresponding version and product license key in your projects to prevent trial license warnings.

Please ensure that you have registered the license key in the entry point of your application


Syncfusion introduced a new licensing system starting with version 16.2.0.x release of Essential Studio. So, these modifications apply to all evaluators and only to paid customers who use NuGet packages from nuget.org.


So, if you are using the Syncfusion NuGet packages from nuget.org, it is must to generate and register the license key in your application.


Please, ensure that all the referenced Syncfusion assemblies\NuGet packages are all on the same version as license key’s version in your project location.

Refer to the following documentation link to get the corresponding version Syncfusion license key,
https://help.syncfusion.com/wpf/licensing/how-to-generate

Refer to this link for registering the license key,
https://help.syncfusion.com/wpf/licensing/how-to-register-in-an-application



Also, license registration is not required for those who uses Syncfusion NuGet packages/Libraries from Essential Studio licensed installer.

If you don’t wish to register the license key in your application, you could download the licensed installer from your licensed account and you can use packages/libraries from that installer in your application. In this case, no need to register the license key and no license message will be displayed.

Find below the details to download and install the licensed version of our installer,
