[Solved] License requirement for windows service that hosts a blazor web site with Telerik controls

[Joel]

My project is a windows service that hosts a blazor web site and api.  When deployed using an MSI, Telerik says it is not licensed.  What must be done with the license file to ensure it is registered?

            int portNumber =
                builder.Configuration.GetValue<int>(
                    "Kestrel:Startup:Port");

            builder.Host.UseWindowsService();
            builder.WebHost.UseKestrel(options =>
            {
                options.Listen(IPAddress.Loopback, portNumber);
            });

Hi Joel,

Can you please provide a small and simple test app together with instructions on how to deploy and run it? I tried creating one with the help of this article, but didn't succeed.

Another thing that you can do is obtain runtime Telerik licensing diagnostic data. This may be faster and potentially sufficient:

1. Call TelerikLicensing.EnableDiagnostics(); very early in the app life cycle, for example, in Program.cs.
2. After the UI and the Telerik license banner shows, collect and save TelerikLicensing.Diagnostics, for example, in a file.
3. Send us the file.

Thank you in advance!

using Telerik.Licensing;

// Call as early as possible, e.g. in Program.cs
TelerikLicensing.EnableDiagnostics();

// Get this later, e.g. in a Razor file
string telerikLicensingDiagnostics = TelerikLicensing.Diagnostics;

[Joel]

Okay, when you create a windows service you can double-click on it to run it in the command window.  Here is what I see from the command window that includes the diagnostics logging:

ADMIN NOTE: REMOVED SCREENSHOT OF LICENSE KEY

Note that I included the telerik-license.txt file as content so it resides in the same directory as the .exe

[Joel]

This is the message it displays:

I will provide a sample project if you still need that in order to solve this

Hi Joel,

Thanks for the update. The log shows that our runtime license validation finds a license only for WPF, but not Blazor:

  ProductMetadata: ProductCode: BLAZOR, ProductName: Telerik UI for Blazor, ProductVersion: 11.2.0.0, LicenseDate: 10/15/2025 12:00:00 AM, RedistributedBy:

The problem may be similar to the scenario in which Telerik UI for Blazor is used by a dependency project or a Razor Class Library:

https://www.telerik.com/blazor-ui/documentation/installation/license-key#using-telerik-packages-in-referenced-projects

My suggestion is to reference the Telerik UI for Blazor NuGet package directly in your main startup project, even if it's the desktop part of the app. If this does not help, then please send us a small isolated solution, which reveals your project structure, so that we can run and test it locally. Thanks.

[Joel]

Finally getting back to this.  Here are my current references:

<ItemGroup>

<PackageReference Include="Serilog.Sinks.Seq" Version="9.0.0" />
</ItemGroup>

I use a classic build pipeline in MS Azure.  I start out by uploading a secure file then using a powerscript file to move the telerik.license file to the expected location.  The errors in the log indicate it is getting and reading the file correctly.  However, the error it gives me indicates that it is a license file for WPF.

When I go to get a new license file... there is no ability to specify which platform I get it for.  It is just a generic download:
https://www.telerik.com/account/your-licenses/license-keys

So, how do I get this to stop pointing at WPF and start pointing to Blazor?

I have attached an example project that turns a blazor app into a windows service.  However, I can't give you a publish pipeline that turns it into an .msi installer.

Hello Joel,

The latest log reveals that you are using a license file, which is not yours (p***@g*************.com). If it's Peter's license key, then your colleague indeed has only a license for WPF.

>> When I go to get a new license file... there is no ability to specify which platform I get it for

The licence key contains all the user's licenses and there is no need to download a license file for a specific product. We may expose such an option in the future to use smaller keys.

[Joel]

Thats quite confusing because we just have a group of Telerik licenses... so, he should have the same as me.  But, he is in charge of the build server... I'll have him update the build server with my license and see if I get any success.

 

[Joel]

I have gone out and downloaded a new license file.  See attached.  During that process, there is nothing that asks me if this is a blazor license or wpf license.  Please review this file to see if it allows for blazor.



I followed this azure pipeline instruction:
https://www.telerik.com/aspnet-core-ui/documentation/deployment/ci-cd-license-key

 

Admin Note: Removed attached file, it was the full license key containing all products in the DevCraft license.

[Joel]

I assume that license file is secure... if not, remove it.

 

[Joel]

Looks like BLAZOR license to me.

 Hi Joel,

  Thank you for the updated diagnostics. We also reviewed the license file you attached on May 5th and decoded its
  contents.

  Your license file is valid and belongs to your account (j***@g*************.com), but it contains licenses only for
  the following products:

   - Kendo UI for Angular
   - Kendo UI Complete
   - Kendo UI for React
   - Kendo UI for Vue

  Telerik UI for Blazor is not included. This is consistent with what your May 6 diagnostics show — the runtime finds
  only a WPF evidence token (RCWPF) and no Blazor token, resulting in IsLicenseValid: False.

  The ProductCode: BLAZOR you see in the log refers to the component assembly being validated, not what your license
  covers — this is a common source of confusion.

  To resolve this, please contact our sales team to add Telerik UI for Blazor to your account: 
  https://www.telerik.com/purchase/blazor-ui

I don't believe your answer to be accurate.  I use the same license to publish my Blazor app to its portal.  I will open a support ticket so I can give you my Blazor app portal.
