使用BackgroundAgent时装配丢失(Assembly missing when using BackgroundAgent)

当我尝试使用BackgroundAgent时，我在系统设置中打开后台应用程序屏幕时收到以下错误消息。

System.IO.FileNotFoundException未处理Message =文件或程序集名称'\ Applications \ Install \ EC78F0AC-625D-482E-9ADD-D48D58BE633A \ Install \ MyAgent.dll'或其中一个依赖项未找到。 StackTrace：位于Microsoft.Phone的Microsoft.Phone.BackgroundAgentActivator.LoadEntryPointAssembly（String assemblyName）的System.Reflection.Assembly.LoadFrom（String assemblyFile）上的System.ThrowHelper.throwVersion37CompatException（ExceptionType newEType，String newString，ExceptionType oldEType，String oldString）。 Microsoft.Phone.BackgroundAgentDispatcher上的Microsoft.Phone.BackgroundAgentDispatcher.AgentRequest.Invoke（）中的Microsoft.Phone.BackgroundAgentActivator.Microsoft.Phone.IBackgroundAgentActivator.CreateBackgroundAgent（String assembly，String typeinfo）中的BackgroundAgentActivator.LoadAgent（String assemblyName，String typeName）。 InvocationThread（）位于System.Threading的System.Threading.Thread.ThreadStartHelper（ThreadHelper t）处System.Threading.ThreadStart_Context（Object state）处于System.Threading的System.Threading.ExecutionContext.Run（ExecutionContext executionContext，ContextCallback callback，Object state）。 ThreadHelper.ThreadStartHelper（）

我使用了本教程： http ： //rodrigueh.com/wp7-live-tiles-with-background-agents 。

提供的样本是有效的，但是当我尝试实现它时它没有..不幸的是我无法在网上找到任何东西。

有什么想法发生了什么？

亲切的问候，尼尔斯

When I try to use a BackgroundAgent I get the following error message when I open up the Background Applications screen at the System Settings.

System.IO.FileNotFoundException was unhandled Message=File or assembly name '\Applications\Install\EC78F0AC-625D-482E-9ADD-D48D58BE633A\Install\MyAgent.dll', or one of its dependencies, was not found. StackTrace: at System.ThrowHelper.throwVersion37CompatException(ExceptionType newEType, String newString, ExceptionType oldEType, String oldString) at System.Reflection.Assembly.LoadFrom(String assemblyFile) at Microsoft.Phone.BackgroundAgentActivator.LoadEntryPointAssembly(String assemblyName) at Microsoft.Phone.BackgroundAgentActivator.LoadAgent(String assemblyName, String typeName) at Microsoft.Phone.BackgroundAgentActivator.Microsoft.Phone.IBackgroundAgentActivator.CreateBackgroundAgent(String assembly, String typeinfo) at Microsoft.Phone.BackgroundAgentDispatcher.AgentRequest.Invoke() at Microsoft.Phone.BackgroundAgentDispatcher.InvocationThread() at System.Threading.ThreadHelper.ThreadStartHelper(ThreadHelper t) at System.Threading.ThreadHelper.ThreadStart_Context(Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStartHelper()

I used this tutorial: http://rodrigueh.com/wp7-live-tiles-with-background-agents.

The sample provided works, but when I try to implement it it doesn't.. Unfortunetly I'm not able to find anything online.

Any ideas what is going on?

Kind regards, Niels

通过查看异常，问题可能是您没有在主项目中引用MyAgent.dll。添加后台任务作为参考，并确保将其添加到WMAppManifest.xml（将其替换为实际程序集名称和任务类的名称。）

By looking at the exception the problem might be that you are not referencing MyAgent.dll in you main project. Add the background task as a reference and make sure this is added to your WMAppManifest.xml (replace it with actual assembly name and name of the task class.)
