Passing test locally, failing on Exercism (GeneratedRegex)

Programming C#
1

I’m not sure how to deal with this, any help would be appreciated. All the tests for my solution pass locally but fail once I submit the solution.

This is for the “Log Levels” exercise in the C# track. The exercise has a project file that specifies the “net8.0” framework, and that is what I am using locally:

❯ dotnet --list-sdks
6.0.425 [C:\Program Files\dotnet\sdk]
7.0.410 [C:\Program Files\dotnet\sdk]
8.0.108 [C:\Program Files\dotnet\sdk]

I can run the tests and they all pass:

❯ exercism test
Running tests via `dotnet test`

Passed!  - Failed:     0, Passed:    11, Skipped:     0, Total:    11, Duration: 29 ms - LogLevels.dll (net8.0)

But when I upload:

We received the following error when we ran your code:

LogLevels.cs(6,34): error CS8795: Partial method 'LogLine._logLineRegex()' must have an implementation part because it has accessibility modifiers.

My solution is using a .NET regular expression source generator:

using System.Text.RegularExpressions;

static partial class LogLine
{
    [GeneratedRegex(@"^\[(?<level>.*)\]:(?<message>.*)$")]
    private static partial Regex _logLineRegex();
    public static string Message(string logLine) => _logLineRegex().Match(logLine).Groups["message"].Value.Trim();
    public static string LogLevel(string logLine) => _logLineRegex().Match(logLine).Groups["level"].Value.Trim().ToLower();
    public static string Reformat(string logLine) => $"{Message(logLine)} ({LogLevel(logLine)})";
}

Am I missing something obvious?

We don’t (yet) support GeneratedRegex, sorry.
