如何在 Silverlight 4 中处理许多相关的 wcf 调用

我尝试与 Silverlight 中 WCF 调用的异步特性成为好朋友。我经常读到“你必须了解异步编程”，我想我已经理解了它的想法和好处。但是我如何处理与 WCF 调用自然同步的进程，而 WCF 调用自然是异步的。例如，从在线数据库加载一个条目，编辑该条目，保存它，执行某些操作，再次加载它，再次编辑它，保存它。如果它使用 Microsoft 模式来做到这一点，我会得到一个无限循环。

public foo()
{
    LoadEntryAsync()
}

LoadEntryCompleted(Entry entry)
{
    entry.counter += 1;
    UpdateEntryAsync(entry);
}


UpdateEntryCompleted(Entry entry)
{
    //do something
    LoadEntryAsync();
}

有人可以帮助我吗？

i try to become a good friend with the asynchronous nature of WCF calls in Silverlight. Often i read "you have to understand asynchronous programming" and i think i have understand the idee and the benefits. But how can i handle processes which are naturally synchron with WCF calls, which are naturally asynchron.
For example, load an entry from an online database, edit the entry, save it, do something, load it again, edit it again, save it.
If it do that with the Microsoft Pattern i get an infinite loop.

public foo()
{
    LoadEntryAsync()
}

LoadEntryCompleted(Entry entry)
{
    entry.counter += 1;
    UpdateEntryAsync(entry);
}


UpdateEntryCompleted(Entry entry)
{
    //do something
    LoadEntryAsync();
}

Can anybody help me?
