Process.Start 在使用 Google Protoc 编译器时挂在 linux

Question

Process.Start 在 linux 中挂起。我正在从 proto 文件生成一个 C# 文件。它运行在某些文件上没问题，但偶尔会挂起。此方法在单独的线程上运行。

    public async Task GenerateCSharpFileAsync(string fileName, string protoFilePath, params string[] args)
    {
        var outputFolder = ""; // some path
        var protocPath = GetProtoCompiler();
        var inputs = $" --proto_path={protoFilePath} --csharp_out={outputFolder} --error_format=gcc {fileName} {string.Join(" ", args)}";

        var psi = new ProcessStartInfo(
            protocPath,
            arguments: inputs
        )
        {
            CreateNoWindow = true,
            WindowStyle = ProcessWindowStyle.Hidden,
            WorkingDirectory = Global.WebRoot,
            UseShellExecute = false
        };

        psi.RedirectStandardOutput = psi.RedirectStandardError = true;

        var proc = new Process { StartInfo = psi };

        try
        {
            proc.Start();

            await proc.WaitForExitAsync();
        }
        catch (Exception ex)
        {
            throw ex;
        }
        finally
        {
            proc.Close();
            proc.Dispose();
        }
    }

从此处引用 WaitForExitAsync()：process.WaitForExit() asynchronously

waitforexitasync 的代码：

    public static async Task WaitForExitAsync(this Process process, CancellationToken cancellationToken = default)
    {
        var tcs = new TaskCompletionSource<bool>();

        void ProcessExited(object sender, EventArgs e)
        {
            Task.Run(() => tcs.TrySetResult(true));
        }

        process.EnableRaisingEvents = true;
        process.Exited += ProcessExited;

        try
        {
            if (process.HasExited)
            {
                return;
            }

            using (cancellationToken.Register(() => Task.Run(() => tcs.TrySetCanceled(), cancellationToken)))
            {
                await tcs.Task;
            }
        }
        finally
        {
            process.Exited -= ProcessExited;
        }
    }

请提供帮助。

出于某种原因，如果服务运行来自命令行，如：dotnet "Test.dll" & 作为后台任务，它会挂起。

尝试了运行ning dotnet "Test.dll" 没有 & 并且工作正常。
