我正在开发一个
WPF应用程序,其中包含一个加载silverlight应用程序的webbrowser控件.我希望能够从visual studio(F5)启动应用程序,并将调试器附加到silverlight代码.但是,我没有运气.
我现在能做的最好的事情就是在没有附加的情况下启动应用程序,然后一旦启动并运行,就可以使用silverlight作为指定类型的代码手动附加到流程,这样就可以了. (当我使Web浏览器控件加载silverlight应用程序时,它将在我的silverlight代码中命中断点).我已经写了一些宏来自动化这个启动/附加,但它仍然不是最好的.
我已经尝试将WPF应用程序指定为在启动/调试silverlight应用程序时运行的外部程序,但Visual Studio会附加到想要调试托管.NET代码的进程.
有任何想法吗？理想情况下,我真的想附加到进程并调试托管的.NET和Silverlight代码,但我不认为这是可能的.我真的很想在启动时自动附加到silverlight代码,以便我可以轻松调试silverlight应用程序的所有问题,包括那些在加载时发生的问题.
解决方法
感谢您的想法Brandorf和脂肪. Brandorf几乎让我到了我想去的地方,但确实要求我的SL应用程序能够独立运行.我真的希望只有一个应用程序,即wpf和silverlight,SL端正在调试.
很久以后我问了这个问题(我忘了我曾经在这里问过),我实际上拼凑了一个我非常满意的解决方案.我在我的应用程序的WPF / .NET端使用visual studio自动化,找到visual studio的所有正在运行的实例,找出哪个生成了我的exe(因为它通常位于vcproj / sln文件夹下面的文件夹中),然后使用visual studio自动化将VS附加到应用程序,调试silverlight代码.完成后,我然后加载我的silverlight内容.
它工作得很好.你最终得到一个应用程序,并找到一个调试器,以便每次运行时附加到自身(所以你可能只希望这个代码在调试版本中,或者某种程度上可以关闭).因此,只要您想调试silverlight端,就可以从visual studio中使用ctrl-F5(无需调试启动)启动应用程序.
这是我的代码：
