Caliburn.Micro(.WP7)和Bing Maps崩溃
问题描述:
我有一个应用程序,我从一些beta版升级 - 而我的地图屏幕崩溃。所以为了达到它的底部 - 我开始了一个全新的“Win Phone应用程序”。Caliburn.Micro(.WP7)和Bing Maps崩溃
引用的Caliburn.Micro版本(距离新代码昨晚建):caliburnmicro_1296ea635677(从CodePlex上)
引用Microsoft.phone.controls.map.dll
和我说
的的MainPage<Grid>
<Maps:Map />
</Grid>
和我添加一个引导程序的App.xaml
<WP7:PhoneBootStrapper x:Name="bootstrapper" />
当页面在电话模拟器中运行时 - 主页面呈现并且我看到世界地图。如果我点击网页的任意位置上 - 我得到的“参数不正确”
未处理的异常,如果我从App.xaml中取出
- 地图上正常工作。
您认为如何?
感谢您的任何建议?
答
我找到了答案。
这里的关键是 - 我有这个设置并且使用Beta模板 - 当我转移到VS2010中的WinPhone RTM模板时它停止工作。
Caliburn代表我做了一些工作,即“添加”到RTM模板 - 彼此冲突。最后,这个问题与Bing Maps控件没有任何关系 - 它恰好就是这样 - 这是我的第一个屏幕 - 所以这就是我试图解决问题的地方。
这是以往任何时候都如此不-有用的例外:
The parameter is incorrect
其中,我敢肯定会发生在任何屏幕上 - 如果你去的模板的升级路径,像我一样。所以这是我必须删除 - 让一切恢复正常。在新的App.Xaml.cs - 我在App构造函数删除(通过评论)...
// Phone-specific initialization
// InitializePhoneApplication();
// Global handler for uncaught exceptions.
// UnhandledException += Application_UnhandledException;
然后,我删除了这些方法体,因为它是从去除InitializePhoneApplication()调用之后刚刚死码ctor ...
// Code to execute when the application is launching (eg, from Start)
// This code will not execute when the application is reactivated
private void Application_Launching(object sender, LaunchingEventArgs e)
{
}
// Code to execute when the application is activated (brought to foreground)
// This code will not execute when the application is first launched
private void Application_Activated(object sender, ActivatedEventArgs e)
{
}
// Code to execute when the application is deactivated (sent to background)
// This code will not execute when the application is closing
private void Application_Deactivated(object sender, DeactivatedEventArgs e)
{
}
// Code to execute when the application is closing (eg, user hit Back)
// This code will not execute when the application is deactivated
private void Application_Closing(object sender, ClosingEventArgs e)
{
}
// Code to execute if a navigation fails
private void RootFrame_NavigationFailed(object sender, NavigationFailedEventArgs e)
{
if (System.Diagnostics.Debugger.IsAttached)
{
// A navigation has failed; break into the debugger
System.Diagnostics.Debugger.Break();
}
}
// Code to execute on Unhandled Exceptions
private void Application_UnhandledException(object sender, ApplicationUnhandledExceptionEventArgs e)
{
if (System.Diagnostics.Debugger.IsAttached)
{
// An unhandled exception has occurred; break into the debugger
System.Diagnostics.Debugger.Break();
}
}
#region Phone application initialization
// Avoid double-initialization
private bool phoneApplicationInitialized = false;
// Do not add any additional code to this method
private void InitializePhoneApplication()
{
if (phoneApplicationInitialized)
return;
// Create the frame but don't set it as RootVisual yet; this allows the splash
// screen to remain active until the application is ready to render.
RootFrame = new PhoneApplicationFrame();
RootFrame.Navigated += CompleteInitializePhoneApplication;
// Handle navigation failures
RootFrame.NavigationFailed += RootFrame_NavigationFailed;
// Ensure we don't initialize again
phoneApplicationInitialized = true;
}
// Do not add any additional code to this method
private void CompleteInitializePhoneApplication(object sender, NavigationEventArgs e)
{
// Set the root visual to allow the application to render
if (RootVisual != RootFrame)
RootVisual = RootFrame;
// Remove this handler since it is no longer needed
RootFrame.Navigated -= CompleteInitializePhoneApplication;
}
#endregion
特别感谢Rob帮助解决这个谜团!
