我有一个奇怪的问题，在我的 App.xaml 中创建派生自 Caliburn.Micro.Autofac.AutofacBootstrapper 的类失败并出现构建错误：
XML 命名空间“clr-namespace:TestProject”中不存在标签“Bootstrapper”
但是，如果我只是在 App.xaml.cs 中创建引导程序，那么一切正常。
下面的代码显示了我可以做些什么来使事情正常进行。如果我取消注释 App.xaml 中的引导程序并注释掉 App.xaml.cs 中的引导程序，我会收到构建错误。
两者有什么不同？
Intellisense 对 App.xaml 中的引导程序很满意，我只在构建时收到错误消息。
这是我的 App.xaml
<Application xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:TestProject"
x:Class="TestProject.App"
>
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary>
<!--
<local:Bootstrapper x:Key="Bootstrapper"/>
-->
</ResourceDictionary>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
这是我的 App.xaml.cs
namespace TestProject
{
public partial class App : Application
{
public App()
{
new Bootstrapper();
this.UnhandledException += this.Application_UnhandledException;
InitializeComponent();
}
private void Application_UnhandledException(object sender, ApplicationUnhandledExceptionEventArgs e)
{
// If the app is running outside of the debugger then report the exception using
// the browser's exception mechanism. On IE this will display it a yellow alert
// icon in the status bar and Firefox will display a script error.
if (!System.Diagnostics.Debugger.IsAttached)
{
// NOTE: This will allow the application to continue running after an exception has been thrown
// but not handled.
// For production applications this error handling should be replaced with something that will
// report the error to the website and stop the application.
e.Handled = true;
Deployment.Current.Dispatcher.BeginInvoke(delegate { ReportErrorToDOM(e); });
}
}
private void ReportErrorToDOM(ApplicationUnhandledExceptionEventArgs e)
{
try
{
string errorMsg = e.ExceptionObject.Message + e.ExceptionObject.StackTrace;
errorMsg = errorMsg.Replace('"', '\'').Replace("\r\n", @"\n");
System.Windows.Browser.HtmlPage.Window.Eval("throw new Error(\"Unhandled Error in Silverlight Application " + errorMsg + "\");");
}
catch (Exception)
{
}
}
}
}
这是 Bootsteapper.cs
namespace TestProject
{
public class Bootstrapper : AutofacBootstrapper<MainPageViewModel>
{
public Bootstrapper()
{
base.ConfigureBootstrapper();
EnforceNamespaceConvention = false;
ViewModelBaseType = typeof(IShell);
}
protected override void ConfigureContainer(Autofac.ContainerBuilder builder)
{
builder.RegisterType<MainPageViewModel>();
base.ConfigureContainer(builder);
}
}
}
