[Solved] Licensing mechanism and AI Agents

[Neil N]

Your licensing mechanism (which is a nuisance at the best of times) seems to be now actively interfering with agentic AI coding.  The newer agents now generate and run scratchpad code and iterate off what they see in the UI.  But they get stuck because your "you need a license key" message overlays everything.  How do I get around this roadblock?

Hi Neil,

Thank you for the provided details. Could you please specify which Telerik product you are using in the app? I am asking as now the forum is opened without setting a specific product. Is the question asked related to a concrete product?

In this case it's UI for WPF.

Given the non-deterministic nature of AI agents, I cannot reproduce this reliably. I will try to capture a video the next time this happens.

Hello, Neil,

Starting with the 2025 Q1 release, Telerik UI for WPF requires activation through a license key. The new licensing model applies to all Telerik products, not just Telerik UI for Wpf. To activate a NuGet-based project successfully, you must do two things: install the Telerik.Licensing package and make the license key available to the account or environment that builds the application. If either part is missing, the build can log errors and warnings and the application can show watermarks or banners at run time - this is expected.

More information about how to activate Telerik UI for WPF license key is available here: WPF Activating Your License Installing License Key - Telerik UI for WPF

If you have already activate your license key, but still facing some licensing related messages, it would be great if you can share more details about these messages or provide the build output. This information would be useful for us to make further investigation.
