vb.net - Application Insights 在加载时因 System.Reflection.TargetInvocationException 失败 - WP 8.1

Question

我开始探索 Application Insights 并尝试将其添加到我的 Windows Phone 8.1 应用程序中。在尝试执行项目时，在 Public Sub New() 内加载时抛出异常。在 App.xaml.vb 中。发生错误的那一行是

TelemetryClient = new TelemetryClient()

抛出的异常是

A first chance exception of type 'System.Reflection.TargetInvocationException' occurred in mscorlib.ni.dll

An exception of type 'System.Reflection.TargetInvocationException' occurred in mscorlib.ni.dll but was not handled in user code

Additional information: Exception has been thrown by the target of an invocation.

内部异常详情:

{System.InvalidOperationException: Type 'Microsoft.ApplicationInsights.Extensibility.ComponentContextInitializer, Microsoft.ApplicationInsights, Version=0.16.1.418, Culture=neutral, PublicKeyToken=31bf3856ad364e35' does not implement the required interface

Microsoft.ApplicationInsights.Extensibility.IContextInitializer. at Microsoft.ApplicationInsights.Extensibility.Implementation.TelemetryConfigurationFactory.CreateInstance(Type interfaceType, String typeName) at Microsoft.ApplicationInsights.Extensibility.Implementation.TelemetryConfigurationFactory.LoadInstance(XElement definition, Type expectedType, Object instance) at Microsoft.ApplicationInsights.Extensibility.Implementation.TelemetryConfigurationFactory.LoadInstances[T](XElement definition, ICollection`1 instances)}

我遵循了概述的步骤 in the Azure documentation .我可能做错了什么？

您是在 Windows 运行时之上还是在 Silverlight 之上使用 Windows Phone 应用程序？

如果您从 ApplicationInsights.config 中删除以下行，您的应用程序是否成功启动？

    <Add Type="Microsoft.ApplicationInsights.Extensibility.ComponentContextInitializer, Microsoft.ApplicationInsights"/>
