This is a small repo created solely to reproduce an error that happens with VS 17.12.3 (.NET 9.0.101) when building a project that uses Blazor.BrowserExtension.Template.

Here's the link for the issue.

To reproduce the error, just try building the project. This is the resulting error:

The "DiscoverPrecompressedAssets" task failed unexpectedly.
System.InvalidOperationException: Fingerprint for '...\ExtensionTest\ExtensionTest\obj\Debug\net8.0\browserextension\build\BackgroundWorker.js' is not defined.
