ConfigureAwait上的ArgumentOutOfRange异常（false）

Question

我有以下功能：

var handlerType = typeof(IQueryHandler<,>).MakeGenericType(query.GetType(), typeof(string));
dynamic handler = _c.Resolve(handlerType);

var test1 = await handler.Run(query);

var test2 = await handler.Run(query).ConfigureAwait(false);

第一个await语句运行正常但第二个语句给了我一个ArgumentOutOfRange异常。我真的不知道为什么会这样。

我使用Autofac解析我的服务。

你能帮帮我吗？
