Targeting net5 using net6 SDK causes pack failure

[stefanloerwald]

To reproduce, create the empty files Component.razor and Component.razor.css (no content required).

As the csproj file use

<Project Sdk="Microsoft.NET.Sdk.Razor">

  <PropertyGroup>
    <TargetFramework>net5.0</TargetFramework>
    <Nullable>enable</Nullable>
  </PropertyGroup>


  <ItemGroup>
    <SupportedPlatform Include="browser" />
  </ItemGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.Components.Web" Version="5.0.9" />
  </ItemGroup>

</Project>

Then run dotnet build and afterwards dotnet pack. The latter will fail with the error message

C:\Program Files\dotnet\sdk\6.0.100-preview.7.21379.14\Sdks\Microsoft.NET.Sdk.Razor\build\netstandard2.0\Microsoft.NET.Sdk.Razor.StaticWebAssets.5_0.targets(436,5):
error : Static web asset 'C:\project\obj\Debug\net5.0\scopedcss\projectbundle\RazorClassLibrary1.bundle.scp.css' has invalid source type ''. [C:\project\project.csproj]

This is using SDK 6.0.100-preview.7.21379.14.

We have the same issue. I tried daily build 6.0.100-rc.1.21411.30 but error still present.

Thanks for contacting us.
@javiercn can you please look into this? Thanks!

[javiercn]

This was fixed in RC1

[javiercn]

@stefanloerwald can you try a nightly build? This is a known limitation we introduced in preview7 as we were doing significant work in the area and we had to scope it for the milestone

[stefanloerwald]

Seems to work with rc1: https://github.com/stefanloerwald/dotnet-sdk-issue-19665/actions/runs/1189053349

[stefanloerwald]

It seems like the fix that was in RC1 previously was reverted? With current RC1, I can reproduce the issue again, see https://github.com/stefanloerwald/dotnet-sdk-issue-19665/runs/3618381368?check_suite_focus=true

When I fetch from the "daily" stream I get rc.1.21417.19, with which there is no issue. If I use 6.0.100-rc.1.21458.32, which to the best of my knowledge is the official RC1 version, I get the error.

[javiercn]

@stefanloerwald I think this was "partially" fixed on RC1 and is truly (hopefully) fixed for good in RC2.

Can you give it a try using RC2 nightly bits?

[stefanloerwald]

Hi @javiercn,

It is unclear to me how I could try RC2. When I last ran the workflow, the daily stream still gave me the RC1 version. The relevant workflow part is

 daily:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2.3.4
    - name: Setup .NET Core
      run: |
        wget https://dot.net/v1/dotnet-install.sh
        bash ./dotnet-install.sh --channel '6.0' --quality 'daily'
    - name: Install dependencies
      run: dotnet restore
    - name: Build
      run: dotnet build
    - name: Pack
      run: dotnet pack

If you could tell me how to adapt that for RC2, I'm happy to make the adjustments and let it run.

[javiercn]

@stefanloerwald something like this should do .\dotnet-install.ps1 -Channel '6.0' -Version 6.0.100-rc.2.21465.13 -InstallDir .\dotnet-sdk-6.0.100-rc.2.21465.13 (note I'm using the powershell version)

[stefanloerwald]

Specifying the version seems to work in the workflow too. Seems like the issue is not in RC2: https://github.com/stefanloerwald/dotnet-sdk-issue-19665/runs/3621929948?check_suite_focus=true

Let's hope it stays like that...

[javiercn]

Yes, we don't plan to make changes in that area unless we really have to for the rest of 6.0. The initial partial fix was the result of a badly authored test that we improved in RC2 (along with a more robust fix), so hopefully things should be ok.

[robertmclaws]

@javiercn How do you get Azure DevOps to download SDKs this way? I put that version in the "Use .NET Core" task and it says "sdk version matching 6.0.100-rc.2.21465.13 could not be found."

Thanks!

[javiercn]

@robertmclaws that build is from like a month ago, I'm not sure how many we retain. You can use the latest available RC2 version which is 6.0.100-rc.2.21505.1

[robertmclaws]

No worries, RC2 just officially came out, so we're upgrading now. Thanks!
