Frequently Asked Questions about Your Telerik UI for .NET MAUI License

This article lists the answers to the most frequently asked questions (FAQs) about working with the Telerik UI for .NET MAUI license key.

Does the license key expire?

Yes, the license key expires at the end of your subscription:

For trial users, this is at the end of your 30-day trial period.
For commercial license holders, this is when your subscription term expires.

You need to download and install a new license key after:

Starting a new trial.
Buying a new license.
Renewing an existing license.
Upgrading an existing license.

An expired perpetual license key is valid for all Telerik UI for .NET MAUI versions published before the license's expiration date.

Will Telerik UI for .NET MAUI function with an expired license key?

This depends on the Telerik UI for .NET MAUI license type (perpetual, subscription, or trial):

Perpetual licenses function normally with an expired license key, as long as the application is using a Telerik UI for .NET MAUI version that was released before the expiration date of the license.
Subscription licenses function normally in already deployed applications, but you cannot rebuild and republish the app.
Trial licenses function normally only within the 30-day trial period.

If none of the above conditions are met, the following behaviors occur:

A modal dialog appears on application startup.
A watermark appears on Telerik UI .NET MAUI components.
A warning message appears in the application's build log.

I updated the Telerik UI for .NET MAUI version in my project and license errors appeared. Why?

The most likely cause is that the new Telerik UI for .NET MAUI version was released after the expiration date of your current license or license key. To fix this issue:

Renew your Telerik UI for .NET MAUI license if necessary.
Download a new license key file and use it to activate the components.

Can I use the same license key in multiple builds?

You can use your personal license key in multiple pipelines, builds, and environments. However, each individual developer must use a unique personal license key.

Do I need an Internet connection to activate the license?

No, the license activation and validation are performed entirely offline.

Do I have to add the license key to source control?

No, you do not have to add the telerik-license.txt license key file or its contents to source control.

Do not store the license key in plain text, for example, in a GitHub Actions Workflow definition. Build servers must use the TELERIK_LICENSE environment variable described in Adding the License Key to CI Services.

What happens if both the environment variable and the license key file are present?

If both the TELERIK_LICENSE environment variable and the telerik-license.txt file are present, then the environment variable will be used.

To use the license key file, unset the environment variable.

What happens if several license key files exist?

If both a global and a project-specific telerik-license.txt files exist, then the project-specific license key will be used.

My team has more than one license holders. Which key do we have to use?

Every developer must be assigned their own license or seat.
Every developer must use a license key that is associated with their personal Telerik account.
In a CI/CD environment, use any of the license keys in your team.

Are earlier versions of Telerik UI for .NET MAUI affected?

No, versions released prior to January 2025 do not require a license key.
