我的应用程序需要将插件加载到单独的应用程序域中,然后异步执行其中的一些代码.我编写了一些代码来包装可Task编组类型:

static class RemoteTask
{
    public static async Task<T> ClientComplete<T>(RemoteTask<T> remoteTask,
                                                  CancellationToken cancellationToken)
    {
        T result;

        using (cancellationToken.Register(remoteTask.Cancel))
        {
            RemoteTaskCompletionSource<T> tcs = new RemoteTaskCompletionSource<T>();
            remoteTask.Complete(tcs);
            result = await tcs.Task;
        }

        await Task.Yield(); // HACK!!

        return result;
    }

    public static RemoteTask<T> ServerStart<T>(Func<CancellationToken, Task<T>> func)
    {
        return new RemoteTask<T>(func);
    }
}

class RemoteTask<T> : MarshalByRefObject
{
    readonly CancellationTokenSource cts = new CancellationTokenSource();
    readonly Task<T> task;

    internal RemoteTask(Func<CancellationToken, Task<T>> starter)
    {
        this.task = starter(cts.Token);
    }

    internal void Complete(RemoteTaskCompletionSource<T> tcs)
    {
        task.ContinueWith(t …
