How do I silence these Telierk build messages.?

[Joe]

We build using the Telerik UI for WPF NuGet Packages from your NuGet server.  Since I updated all our Telerik NuGet package references from a 2024 version to the most current 2025 version, I am now receiving licensing messages during my build process.  A lot of licensing messages.  They tend to look like this:

17>[Telerik and Kendo UI Licensing]
17>      Telerik and Kendo UI License Key found at: C:\Users\joe\AppData\Roaming\Telerik\telerik-license.txt (UserDirectory)
17>      License issued at 2025-02-25 to j*******@g*******.com.
17>[Telerik and Kendo UI Licensing]

And they are all over the place.

Please tell me that there is a way that I can silence these messages

They make it more difficult to locate the build output lines that I am truly interested in.  I don't need this information but if it must be output I don't need it this many times.

Hello Joe,

At this point, there is no mechanism to disable the message printed in the output. However, I've forwarded your feedback to the team resonsible for the licensing functionality, so they can review and consider this idea for the future.

In case you need further assistance, please let me know.

Please let them know it is not just one customer that wants these messages reduced.

We have 25 projects in one of our main products. Building it generates 142 lines of output of which 43 are lines of extra messaging caused by Telerik.  30 of which are like the lines below, 13 of duplicated normal build warnings that appear to be caused by the license processing. Thus, something like 30% of the build output is noise caused by the new licensing. Quite a lot when the build output verbosity is set to minimal in Visual Studio 2022. 

25>  [Telerik and Kendo UI Licensing]
25>        Valid Telerik UI for WinForms license found.
25>  [Telerik and Kendo UI Licensing]
25>        Valid Telerik UI for WPF license found.
25>  [Telerik and Kendo UI Licensing]
25>        Valid Telerik Reporting license found.
25>  [Telerik and Kendo UI Licensing]
25>        Valid Telerik Document Processing Libraries license found.

 

Maybe consolidate the lines and only report once per solution build? Add extra lines if needed for diagnostics when the verbosity is set higher?

I should add that this is with 2025.2 release.  I see the lines are down a little from what was showing with the prior build.

Hey Jeff, we've already introduced a feature to disable this with the latest version of Telerik.Licensing. Will post it in an answer below (instead of comment) so it is more visible.

Hello,

We've already introduced a setting to disable the message in the output which says that a Telerik license was found. To hide this from the output, use the following parameter in the CL during build:

-p:TelerikLicensingVerbosity=quiet

Or add the following tag in the .csproj file:

<TelerikLicensingVerbosity>quiet</TelerikLicensingVerbosity>
