ApplyCompressionNegotiation build task fails when RCL references a Nuget RCL with StaticWebAssetBasePath set to / #110321

Open LostBeard opened 4 hours ago

Description

Issue

The .Net 9 Blazor WASM compression build task, ApplyCompressionNegotiation, fails due to an unknown issue handling Razor Class Library Nuget packages that use <StaticWebAssetBasePath>/</StaticWebAssetBasePath> when referenced by another Razor Class Library

Reproduction Steps

Steps to reproduce

  1. Create a solution with a .Net 9 Razor Class Library (RCL) and set <StaticWebAssetBasePath>/</StaticWebAssetBasePath> in its .csproj.
  2. Publish the RCL as a Nuget package (publishing locally is fine)
  3. Create a new solution with an .Net 9 Razor Class Library and a .Net 9 Blazor WebAssembly Standalone App
  4. In the RCL, reference the Nuget package from step 2 (has to reference Nuget package, not a project reference!)
  5. In the Blazor WASM app reference the RCL project in the same solution (from step 3)
  6. Publish the Blazor WASM

You get an exception similar to:

A workaround that will enable a publish build is to modify the .csproj of the Nuget package project.

Changing:
<StaticWebAssetBasePath>/</StaticWebAssetBasePath>

To:
<StaticWebAssetBasePath>/./</StaticWebAssetBasePath>

!! IMPORTANT The above workaround breaks debugging. Assets from the Nuget package will be correctly added to publish builds but will fail to load in debug builds.

This issue started as a report about an issue (#4) with SpawnDev.BlazorJS.WebWorkers.

Repo: WebWorkers.Issue4

Repo demo projects

The projects in this repo demonstrate this bug.

RazorClassLibrary2 is the project that needs to be packaged as a Nuget package and that package (not the project) referenced by RazorClassLibrary1.

If <StaticWebAssetBasePath> is set to / in the referenced RazorClassLibrary2 Nuget package, the publish of WebWorkers.Issue4 will fail.

Using a RazorClassLibrary2 Nuget package with <StaticWebAssetBasePath>/./</StaticWebAssetBasePath> and the publish succeeds. But debugging will fail (404 for the Nuget web assets).

Expected behavior

I expected StaticWebAssetBasePath to work in .Net 9 as it did in .Net 8. This issue did not exist in .Net 8.

Actual behavior

publish builds fail with the error Endpoints not found for compressed asset:

Regression?

No response

Known Workarounds

Disable compression with <CompressionEnabled>false</CompressionEnabled> in app .csproj.

One workaround is to disable compression and the publish builds will succeed.

In the Blazor WASM project's .csproj 

<PropertyGroup>
    <CompressionEnabled>false</CompressionEnabled>
</PropertyGroup>

Another is to use .Net 8 instead of .Net 9 as the issue does not occur in .Net 8.
