Lack of build when using BackgroundAgent

When I try to use BackgroundAgent, I get the following error message when I open the Background Applications screen in the system settings.

The System.IO.FileNotFoundException error 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. Stack traces: in System.ThrowHelper.throwVersion37CompatException (ExceptionType newEType, String newString, ExceptionType oldEType, String oldString) in System.Reflection.Assembly.LoadFrom (String assemblyFile) in Microsoft.Phone.BackgroundAgentActivator.LoadEntryPoint Assembly .BackgroundAgentActivator.LoadAgent (String assemblyName, String typeName) on Microsoft.Phone.BackgroundAgentActivator.Microsoft.Phone.IBackgroundAgentActivator.CreateBackgroundAgent (String assembly, typeinfo string) on ​​Microsoft.Phone.BackgroundAgentDispatcher.AgentRehone.Background.AgentRehone.Background.AgentRehone.Background. .InvocationThread () in System.Threading.ThreadHelper.ThreadStartHelper (ThreadHelper t) in System.Threading.ThreadHelper.ThreadStart_Context (object state) in System.Threading.ExecutionContext.Run (ExecutionContext executeContext, of inverse challenge ContextCallback, object state) in System.Threading.ThreadHelper.ThreadStartHelper ()

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

The given sample works, but when I try to implement it, it does not. Unfortunately, I can not find anything on the Internet.

Any ideas what is going on?

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

<ExtendedTask Name="BackgroundTask"> <BackgroundServiceAgent Specifier="ScheduledTaskAgent" Name="MyAgent" Source="MyAgent" Type="MyAgent.ScheduledAgent" /> </ExtendedTask>
