Update .NET SDKs

[martincostello]

What are you trying to accomplish?

Update .NET 8 and 9 SDKs to their latest versions - the main motivation to use the latest .NET 9 release candidate.

Anything you want to highlight for special attention from reviewers?

No.

How will you know you've accomplished your goal?

The build is green.

I'm not sure why the tests are failing - will take a look tomorrow.

@martincostello it looks like we might have been working around a bug you logged upstream, that has since been fixed: dotnet/msbuild#10682. In nuget/spec/dependabot/nuget/native_helpers_spec.rb

 it "contains the expected output" do
  # In CI when the terminal logger is disabled by default in .NET 9 there is no
  # output from the test runner: https://github.com/dotnet/msbuild/issues/10682.
  # Instead we have to rely on the cmd invocation failing with a non-zero exit code
  # if any tests fail. Locally when the terminal logger is enabled we can check
  # there is an absence of any evidence of test failures in the output.
  # expect(dotnet_test).to include("Passed!")
  expect(dotnet_test).not_to include("Build failed")
end

Well, well, well, if it isn't the consequences of my own actions 😆

I'll fix that up in the morning.

Still debugging, but it looks like it's not the issue being fixed (it's still open, which makes sense), but that because of the bug, we can't see why the tests are failing.

Running them locally, one fails:

Just saw, the issue is fixed, but it didn't make it into RC2 so will be in 9.0.100.

[martincostello]

This version was changed since RC1 by dotnet/sdk#41936, and it's going to change again with dotnet/sdk#43889 to .46, so will probably need changing next month when updating to 9.0.100.

[martincostello]

I'm not sure why the lockfile smoke test is failing.

The error is:

updater | /tmp/package-dependency-resolution_kuH1Yp/Project.csproj : error NU1102: Unable to find package Microsoft.WindowsDesktop.App.Ref with version (= 8.0.10)
updater | /tmp/package-dependency-resolution_kuH1Yp/Project.csproj : error NU1102:   - Found 120 version(s) in nuget.org [ Nearest version: 9.0.0-preview.1.24081.3 ]

but the package is in NuGet.org: Microsoft.WindowsDesktop.App.Ref@8.0.10.

Maybe the test depends on whatever version of the .NET SDK happens to be installed on the hosted runner?

[martincostello]

From the build logs:

#10 [ 5/15] RUN dotnet --list-runtimes
#10 0.181 Microsoft.AspNetCore.App 8.0.10 [/usr/local/dotnet/current/shared/Microsoft.AspNetCore.App]

When I do the same locally on my Windows machine:

Microsoft.AspNetCore.App 6.0.35 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.AspNetCore.App 7.0.20 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]

Microsoft.WindowsDesktop.App 9.0.0-rc.2.24474.4 [C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App]

Maybe the issue is that Microsoft.WindowsDesktop.App isn't being installed? Though, if that is the case, I'd have thought the tests would be broken already?
