Incompatibility with .NET SDK 9.0.304 and 10.0.100-rc.1-25451.107

[bradwilson]

Describe the bug

When building a .NET 9 project with .NET SDK 9.0.304 and 10.0.100-rc1 installed, the build fails with the following error:

Error: C:\Program Files\dotnet\sdk\10.0.100-rc.1.25451.107\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.FrameworkReferenceResolution.targets(442,5): error NETSDK1127: The targeting pack Microsoft.NETCore.App is not installed. Please restore and try again. [D:\a\xunit\xunit\src\xunit.v3.assert.compat\xunit.v3.assert.all-on\xunit.v3.assert.all-on.csproj::TargetFramework=net9.0]

To Reproduce

This is being done on GitHub Actions, whose agents currently have 9.0.304 installed.

https://github.com/xunit/xunit/actions/runs/17740351193

To fix this, I forced an installation of 9.0.305 onto the agent:

https://github.com/xunit/xunit/actions/runs/17740712152

Note that I experienced the same issue on my personal dev box (which had 9.0.302 installed, as I had not yet updated VS2022). I'd written this off as being a local configuration issue related to uninstalling .NET 10 SDK Preview 7. Once it reproduced in Actions, I changed my belief to be that there is a compatibility issue, as the Actions agent has never had .NET 10 installed before I installed it during setup.

@baronfel for attention.

[baronfel]

@bradwilson is it possible to get a binlog of the erroring build by chance? This is a highly dynamic part of the targets and the behavior can vary drastically based on the inputs, so it's hard to say anything concretely.

[bradwilson]

We don't generate binlogs in CI (too much potential to leak secrets). I could try to get a VM set up (or maybe WSL, if it also repros on Linux) to repro the situation, since my local machine has 9.0.305 installed already.

[baronfel]

Thanks - I appreciate the effort! If it's easier to have a minimal repro that we could clone/download and run that would be just as good 👍

[bradwilson]

I was unable to repro with WSL (Ubuntu 24.04) so I'm setting up a VM right now.

[bradwilson]

I'm also unable to get this to repro in a clean VM. I don't know what the missing X factor is for getting a repro, other than "it's broken in Actions and used to be broken on my PC". ☹️

[baronfel]

Interesting - in your CI you do a --no-restore, how are you doing the restore phase of this build? What seems to be happening is that the 10 SDK thinks that you need the 9.0.9 versions of the frameworks you're targeting:

This is what I'd expect for RC1. Can you confirm on your CI machine if C:\Program Files\dotnet\packs\Microsoft.NETCore.App.Ref\9.0.9 exists?

[bradwilson]

Interesting - in your CI you do a --no-restore, how are you doing the restore phase of this build?

According to dotnet --info, it should not be there.

9.x SDKs:

  9.0.109 [C:\Program Files\dotnet\sdk]
  9.0.205 [C:\Program Files\dotnet\sdk]
  9.0.304 [C:\Program Files\dotnet\sdk]

9.x Runtimes:

  Microsoft.NETCore.App 9.0.6 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
  Microsoft.NETCore.App 9.0.8 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]

I don't have direct access to the Actions image, but I would have no reason to believe that it should be there, either, since in both failing cases (my local box and the Actions image), SDK 9.0.305 had never been installed, which would've been how runtime 9.0.9 would show up.

I'll grab a binlog for the restore and see if there's anything useful in there for you.
