I use Blazor server 9. I am experiencing an issue with my Blazor Server application that utilizes DevExpress components after publishing via VS2022 to azure. The application functions correctly when hosted on Everleap, but encounters problems on Azure App Service. Specifically, the DevExpress licensing file, dx-license-e00a5bc7.js, is not being published to Azure, leading to errors in the application.
Issue Details:
- Application Type: Blazor Server 9
- DevExpress Components: Yes
- Problem: The
dx-license-e00a5bc7.jsfile, essential for DevExpress licensing, is not being deployed to Azure App Service. This results in the application failing to load DevExpress components properly. - Deployment Method: Visual Studio 2022 Publish
Observations:
- The application works as expected on Everleap hosting, with the
dx-license-e00a5bc7.jsfile present and loaded correctly. - On Azure App Service, the
dx-license-e00a5bc7.jsfile is missing from the deployed files. - The file is not listed in the publish preview within Visual Studio 2022 when deploying to Azure.
Steps Taken:
- Verified Publish Settings:
- Checked the project’s publish settings in Visual Studio 2022. The
dx-license-e00a5bc7.jsfile does not appear in the list of files to be published.
- Checked the project’s publish settings in Visual Studio 2022. The
- Examined Project File (csproj):
- Reviewed the project file to ensure there are no exclusions or conditions preventing the file from being published.
- Manual Inclusion Attempt:
- Attempted to manually include the
dx-license-e00a5bc7.jsfile by setting its Build Action to "Content" and "Copy to Output Directory" to "Copy if newer." This did not resolve the issue.
- Attempted to manually include the
- Checked Azure App Service Configuration:
- Verified that Azure App Service is configured to serve static files and that there are no restrictions or configurations that might prevent the
dx-license-e00a5bc7.jsfile from being served.
- Verified that Azure App Service is configured to serve static files and that there are no restrictions or configurations that might prevent the
Request:
I seek guidance on how to ensure that the dx-license-e00a5bc7.js file is included when publishing the application to Azure App Service using Visual Studio 2022. Are there specific configurations or steps required to include this file in the deployment process?
Your assistance in resolving this matter would be greatly appreciated.

First make sure the
dx-license-e00a5bc7.jsfile is placed inside thewwwrootfolder of your Blazor project. Azure and Blazor treat this folder as the home for all static files like JavaScript, CSS, and images. If the file is located elsewhere, it may be skipped during publish.Next, in Visual Studio, right-click the file and choose Properties. Then, set Build Action to
Content, and for Copy to Output Directory, chooseDo not copy(or leave it as-is if it's already underwwwroot). This tells Visual Studio that the file is a static content asset and should be included when publishing.Then, open your project’s
.csprojfile and check if the file is listed under an<ItemGroup>like this:<ItemGroup> <Content Include="wwwroot\dx-license-e00a5bc7.js" /> </ItemGroup>This entry ensures the file is considered for publishing. Also, make sure nothing else in your
.csprojis overriding or excluding content files.Do a full Clean and Rebuild of the solution in Visual Studio. Then go to your Publish profile, click Publish > Show Preview, and verify that the
dx-license-e00a5bc7.jsfile is listed in the files to be deployed. If it shows up, go ahead and publish again to Azure App Service.Once deployed, open the Kudu Console at
https://<your-app-name>.scm.azurewebsites.net/DebugConsole, navigate to thesite/wwwrootfolder, and confirm that the file is present. If it is, your DevExpress components should now load correctly.If for some reason the file still doesn’t get published, you can add a custom command in the
.csprojto explicitly copy it during publish:<Target Name="IncludeDevExpressLicenseFile" AfterTargets="Publish"> <Copy SourceFiles="wwwroot\dx-license-e00a5bc7.js" DestinationFolder="$(PublishDir)wwwroot" /> </Target>Lastly, ensure that your app references the license file in your Blazor layout or main page. In
_Host.cshtmlorindex.html, add:<script src="dx-license-e00a5bc7.js"></script>This helps the browser load it correctly at runtime.
