Support .NET 9 #10593

martincostello · 2024-09-12T14:17:43Z

What are you trying to accomplish?

Support .NET 9 by installing both the STS and LTS releases of .NET.

Relates to #10496, but doesn't resolve it in the general case (i.e. it won't work for .NET 10).

Anything you want to highlight for special attention from reviewers?

As .NET 9 is in RC and not "official" yet, I figured the least risky option (at the expense of increasing the image size) was to install both .NET 8 and .NET 9. These could then be updated on alternate years (LTS changes to 10 next year, STS changes to 11 in 2026, etc.)

The .NET 9 SDK also makes NuGet Audit enabled by default and breaks package restore when vulnerable packages are in the dependency tree. I've resolved that for building NuGetUpdated, but it might occur when upgrading users' own projects. I couldn't see an obvious place in the code to change the tool to set NuGetAudit=false to avoid that when updating packages. I did do a search for NoWarn, but those all seemed to be in projects being built rather than when invoking the tool.

How will you know you've accomplished your goal?

Dependabot can update NuGet packages for projects targeting net9.0.

Try to fix warnings building NuGetUpdater with the .NET 9 SDK from NuGet Audit.

Disable NuGet audit when running the native C# tests, as they don't seem to otherwise obey the changes in Directory.Build.props of the project itself.

I'm going to move this out of draft so that someone who knows Ruby and the repo layout can point me at where I need to make the changes to make the build happy.

Update tests for the changes to the output format of `dotnet test` in .NET 9.

Forcibly enable the terminal logger in CI so the expected test output is present.

Attempt to run the tests with the .NET 8 SDK instead of .NET 9 to see if it fixes the failing tests.

Add cwd.

Account for extra parameter.

Revert to the expected output for .NET 8 SDK.

martincostello · 2024-09-21T12:02:48Z

Changing the C# tests to run in the current working directory of NuGetUpdater to force it to use the .NET SDK from global.json instead of rolling forward to the .NET 9 SDK has fixed one of the tests, but 4 tests are failing for NuGetUpdater.Core.Test for some reason I need to dig into.

- Fix tests broken by error about usage of CPVM. - Update Microsoft.Windows.SDK.NET.Ref version.

Add missing line to expected contents.

Add the C# Dev Kit extension to the devcontainers.

Install the .NET 9 SDK in the devcontainer.

Update NuGetUpdater to target .NET 9 so that tests can test compatibility with `net9.0`.

This change is to resolve a compiler ambiguity with the addition of a params ReadOnlySpan<T> overload added in .NET 9.

The change to force the ruby tests for C# to use the version of the .NET SDK in global.json for NuGetUpdater cause an error that package versions shouldn't be used in projects using central package management. I think this is because the build then picks up the Directory.Packages.props file in that directory despite the test project not being in the directory tree of that file.

Update script to build for .NET 9.

To test net9.0, the tests have to target net9.0 due to this logic for setting up the local package repository used in the tests:

dependabot-core/nuget/helpers/lib/NuGetUpdater/NuGetUpdater.Core.Test/MockNuGetPackage.cs

Lines 332 to 337 in fa8d392

// find the actual SDK directory

string privateCoreLibPath = typeof(object).Assembly.Location; // e.g., C:\Program Files\dotnet\shared\Microsoft.NETCore.App\8.0.4\System.Private.CoreLib.dll

string sdkDirectory = Path.Combine(Path.GetDirectoryName(privateCoreLibPath)!, "..", "..", "..", "sdk", sdkVersionString); // e.g., C:\Program Files\dotnet\sdk\8.0.204

string bundledVersionsPropsPath = Path.Combine(sdkDirectory, "Microsoft.NETCoreSdk.BundledVersions.props");

FileInfo normalizedPath = new(bundledVersionsPropsPath);

return normalizedPath.FullName;

Otherwise the file read doesn't contain support for .NET 9, and then the local package repo doesn't contain any of the required fake packages and dotnet restore fails for net9.0 projects.

Update the assertions for the Ruby tests for C# to account for the behaviour changes for the new terminal logger.

If this test were skipped, the need to update NuGetUpdater to net9.0 itself can be reverted. Otherwise, the tests need reworking in some way to discover .NET SDK versions without relying on the exact version of .NET the tests are executing with.
