为32位Intel体系结构构建时，在WebFrame中加载Silverlight网站

我正在使用

WebFrame

将请求加载到运行Microsoft SilverLight的网站。当我使用64位Intel体系结构（x86_64）构建应用程序时，它运行良好。但是，因为我必须使用为32位Intel构建的第三方库，所以我必须使用该体系结构构建我的应用程序。当我这样做时，我会得到以下错误消息

<Error>: clip: empty path.

我的应用程序最终崩溃或挂起

有没有人遇到过这个问题，并且知道可能是什么问题？为什么只有在构建32位Intel体系结构时才会发生这种情况

值得一提的是，以下是崩溃的堆栈跟踪：

我想知道你是否被我在回答中概述的第一个问题击中了。我看到您没有使用Mono，但是您使用的是webView，崩溃堆栈看起来非常相似。在类似的情况下，我们中的许多人都有幸更改了useragent字符串…

Hmmm。。非常有趣。它们看起来确实非常相似。我不再从事这个项目了，但如果我是，我肯定会尝试一下。这当然可能是个问题。谢谢你发帖！没问题。它也很容易成为问题2（或两者兼而有之：-P）-SL+Mac=blech：-/
