 # Syncfusion<sup style="font-size:70%">&reg;</sup> Licensing Overview
 
-We have introduced a new licensing system starting with version 16.2.0.x release of Essential Studio<sup style="font-size:70%">&reg;</sup>. These modifications apply to all evaluators and only to paid customers who use NuGet packages from [nuget.org](https://www.nuget.org/). Starting with v16.2.0.x, if you use the evaluation installer or the NuGet feed to reference Syncfusion<sup style="font-size:70%">&reg;</sup> assemblies, you must also include the corresponding platform and version license key in your projects.
+Starting with the version 16.2.0.x release of Essential Studio<sup style="font-size:70%">&reg;</sup>, Syncfusion<sup style="font-size:70%">&reg;</sup> introduced a new licensing system. These modifications apply to all evaluators (trial users) and to paid customers who reference Syncfusion<sup style="font-size:70%">&reg;</sup> assemblies through the [nuget.org](https://www.nuget.org/) feed. Starting with v16.2.0.x, if you use the trial installer or the NuGet feed to reference Syncfusion<sup style="font-size:70%">&reg;</sup> assemblies, you must also include the corresponding version license key in your projects.
 
-The Syncfusion.Licensing NuGet package does not need to be added to your project individually. If you install any Syncfusion<sup style="font-size:70%">&reg;</sup> NuGet packages from [nuget.org](https://www.nuget.org/) to your project, the Syncfusion.Licensing package will be added automatically to the dependencies of your project. If it is not added, you can manually add the [Syncfusion.Licensing](https://www.nuget.org/packages/Syncfusion.Licensing) package from nuget.org.
+The Syncfusion License Key is a unique string that must be registered in your application before initializing any Syncfusion controls. Registering the license key ensures that your application runs without licensing validation messages when using Syncfusion assemblies or NuGet packages.
 
-## Difference between unlock key and license key
+N> Don't use the Unlock Key instead of the License Key in your application. The Unlock Key is used only for installing the Syncfusion offline installer. This key typically starts with @ and ends with =.
 
-Please note that this license key is different from the installer unlock key that you might have used in the past and needs to be separately generated from Syncfusion<sup style="font-size:70%">&reg;</sup> website. Refer [this](https://www.syncfusion.com/kb/8950/difference-between-the-unlock-key-and-licensing-key) KB article to know more about difference between the Syncfusion<sup style="font-size:70%">&reg;</sup> Unlock Key and the Syncfusion<sup style="font-size:70%">&reg;</sup> License Key.

-Following licensing error will be shown if the license key is not registered in your projects, while using assemblies from evaluation installer or from the nuget.org.

+## Registering the license key in your application
+
+The license key is a runtime string that must be registered before any Syncfusion<sup style="font-size:70%">&reg;</sup> control is initialized. A minimal registration call is shown below.
+
+**Registering a single license key (C#)**
+
+```csharp
+Syncfusion.Licensing.SyncfusionLicenseProvider.RegisterLicense("YOUR_LICENSE_KEY");
+```
 
+Starting with v31.1.17, if your application uses components from multiple editions (for example, the UI Edition **and** the PDF Viewer SDK), register each generated license key. Refer to [How to Register the License Key in the Application](https://help.syncfusion.com/common/essential-studio/licensing/how-to-register-in-an-application) for the complete set of platforms (ASP.NET Core, Blazor, JavaScript, Java, etc.) and placement guidance (startup, Main, appsettings.json, environment variable).
