The Licensing Client (.NET)

The Zentitle.Licensing.Client library serves as a C# SDK, streamlining the integration of applications with Zentitle2 Licensing API functionality, thus simplifying the implementation task for the developers.
The library provides 2 ways to integrate the Zentitle2 features into your system:
  1. 1.
    Use IActivation class that represents the Zentitle2 license in your application. This is the preferred approach, as the activation instance handles the state of the license for you, making sure that the activation data are persisted correctly, keeping the number of API calls as low as possible. It provides appropriate methods to move between the possible license states and allows the developers to easily leverage all the Licensing API features.
  2. 2.
    Use generated LicensingClient class, which acts as a strongly typed, error-handling proxy for all the calls to the Licensing API. However, it's worth noting that this method is more intricate and not suggested, as it necessitates the developer to implement the logic for persisting and loading the local license state, as well as handling errors and transitioning between the states (such as active or expired) and many other things covered by the IActivation abstraction.
There are 2 ways of adding the SDK into your application:
  1. 1.
    Copy & paste the source code into your codebase. This approach will result in a single compiled assembly, which will contain both your app logic as well as licensing features and it won't allow the attacker to replace the Zentitle.Licensing.Client.dll with a malicious one on the hosting machine. On the other side, it will make the process of upgrading the SDK to newer versions much less straightforward. The client code is stored in Github.
  2. 2.
    Reference the Zentitle.Licensing.Client Nuget package. The Nuget package targets frameworks .NET Standard 2.0 and .NET Framework 4.5.
There are various configuration options for the SDK, which are explained on the Configuring the Activation page.
