Steps To Reproduce

WorldExplorer App Test Steps:
The machine has dotnet-sdk-9.0.100-preview.7.24353.17 sdk installed.
1.Open command prompt window and navigate to src\WebApp\ folder.
2. Run "dotnet new globaljson" command. It will generate a global.json file with 9.0.100-preview.7.24353.17 sdk version assigned.
3. dotnet build WebApp.csproj

Expected Result:
Build successfully.

Minimal Repro steps (Demo attached): ResolvedCompressedAssesstsDemo.zip

1.Create a .NET 8.0 Blazor web app project.
2. Install Toolbelt.Blazor.I18nText (version 12.0.2) nuget package.
3. Registry the I18nText service in Program.cs file:

using BlazorApp1.Components;
using Toolbelt.Blazor.Extensions.DependencyInjection;
var builder = WebApplication.CreateBuilder(args);
builder.Services.AddI18nText();

4. Create a folder named "i18ntextRun"
5. Create a file named "Translation.en.json" under "i18ntext" folder with below content:

{
"DangerZone": "Danger Zone"
}

6. Set the Build Action for Translation.en.json file as "C# analyzer additional file".
7. Run "dotnet new globaljson" command. It will generate a global.json file with 9.0.100-preview.7.24353.17 sdk version assigned.
8. Build the project.

Expected Result:
Build successfully.

Anything else?

Findings:
This issue started from dotnet-sdk-9.0.100-preview.5.24277.8. We filed it in #56288 and there is a fix for the bug. But that only fix QuickApp app, WorldExplorer app still have this issue.

@Junjun-zhao thanks for contacting us.

This seems to be an issue with one of the libraries being used Toolbelt.Blazor.I18nText which seems to be incorrectly integrating with our static web assets feature. Instead of directly defining the assets, the recommended approach is to generate the content before AssignTargetPaths and before ResolveProjectStaticWebAssets runs and defining Content items either on the wwwroot folder directly or using the TargetPath property pointing to the location on the wwwroot folder instead of directly defining the assets like they are doing right now.

  <!-- FOR SUPPORT TO .NET 6 or later Razor SDK - NEW STATIC WEB ASSETS ARCHITECTURE -->

  <Target Name="_ResolveBlazorI18nTextStaticWebAssets" Condition=" $(I18nTextNewStaticWebAssetsArchitecture) " DependsOnTargets="_IncludeGeneratedI18nTextResourceJsons">

      <_BlazorI18nTextStaticWebAsset Include="@(ContentWithTargetPath)" Condition="$([System.String]::Copy('%(TargetPath)').Replace('/','\').StartsWith('wwwroot\_content\i18ntext\'))" />
      <StaticWebAsset Include="@(_BlazorI18nTextStaticWebAsset)">

    </ItemGroup>
  </Target>

Filed jsakamoto/Toolbelt.Blazor.I18nText#63 on the library, but this is by design. Libraries should integrate by providing Content items instead of directly generating static web assets.

@javiercn OK, I'll fix the "I18nText" library on my side, following your advice. Thank you for explaining that!
