これを使用して、「job_object_limit_kill_on_job_close」を子プロセスに設定しようとしました:

int pid = System.Diagnostics.Process.GetProcessesByName("Child")[0].Id;
Job job = new Job("TEST JOB");
job.AddProcess(Process.GetProcessById((int)pid).Handle);

Process Explorer を使用すると、子プロセスに割り当てられたジョブ「TEST JOB」が表示されましたが、どういうわけかジョブ制限がリストされていません...ただ空です。

何が原因でしょうか?

私が使用しているクラスは次のとおりです。

public class Job : IDisposable
{
    [DllImport("kernel32.dll", CharSet = CharSet.Unicode)]
    static extern IntPtr CreateJobObject(IntPtr a, string lpName);

    [DllImport("kernel32.dll")]
    static extern bool SetInformationJobObject(IntPtr hJob, JobObjectInfoType infoType, IntPtr lpJobObjectInfo, UInt32 cbJobObjectInfoLength);

    [DllImport("kernel32.dll", SetLastError = true)]
    static extern bool AssignProcessToJobObject(IntPtr job, IntPtr process);

    private IntPtr handle;
    private bool disposed;

    public Job(string jobName)
    {
        handle = CreateJobObject(IntPtr.Zero, jobName);

        var info = new JOBOBJECT_BASIC_LIMIT_INFORMATION
        {
            LimitFlags = 0x2000
        };

        var extendedInfo = new JOBOBJECT_EXTENDED_LIMIT_INFORMATION
        {
            BasicLimitInformation = info
        };

        int length = Marshal.SizeOf(typeof(JOBOBJECT_EXTENDED_LIMIT_INFORMATION));
        IntPtr extendedInfoPtr = Marshal.AllocHGlobal(length);
        Marshal.StructureToPtr(extendedInfo, extendedInfoPtr, false);

        if (!SetInformationJobObject(handle, JobObjectInfoType.ExtendedLimitInformation, extendedInfoPtr, (uint)length))
            throw new Exception(string.Format("Unable to set information.  Error: {0}", Marshal.GetLastWin32Error()));
    }

    public void Dispose()
    {
        Dispose(true);
        GC.SuppressFinalize(this);
    }

    private void Dispose(bool disposing)
    {
        if (disposed)
            return;

        if (disposing) { }

        Close();
        disposed = true;
    }

    [DllImport("kernel32.dll", SetLastError = true)]
    [return: MarshalAs(UnmanagedType.Bool)]
    static extern bool CloseHandle(IntPtr hObject);

    public void Close()
    {
        CloseHandle(handle);
        handle = IntPtr.Zero;
    }

    public bool AddProcess(IntPtr processHandle)
    {
        return AssignProcessToJobObject(handle, processHandle);
    }

    public bool AddProcess(int processId)
    {
        return AddProcess(Process.GetProcessById(processId).Handle);
    }

}

何も問題はありません。ProcessExplorerはkilloncloseフラグを表示しません。表示されるのは、ジョブのメモリとプロセスの制限です。

仕事を終えたときに子プロセスが終了することをテストして確認しましたか？プログラムが正しく動作している限り、外部ツールが何を表示しているかを心配する必要はありません。
