As I was developing my first Metro App today I came upon this weird error.
Error 1 Error : DEP0600 : The following unexpected error occurred during deployment: Illegal characters in path. at System.IO.Path.CheckInvalidPathChars(String path, Boolean checkAdditional) at System.IO.Path.Combine(String path1, String path2) at Microsoft.VisualStudio.ImmersiveProjectServices.Shared.AppxLayoutManager.CheckPackageLayoutState(DeployPackageName deployPackageName, String location) at Microsoft.VisualStudio.ImmersiveProjectServices.Shared.LocalDeployJob.GetLayoutState(DeployPackageName deployName, Boolean hasFrameworkDependencies) at Microsoft.VisualStudio.ImmersiveProjectServices.Shared.RegisterAppxLayout.Start(Boolean forceNewLayout, Boolean forceRegistration, NetworkLoopbackState desiredNetworkLoopbackState, Boolean refreshLayoutOnly, String& packageMoniker, String& firstUserAppID, Exception& deployException)
Not knowing what to do, because the error is vague and cryptic. I decided to throw a hail mary pass and remove the application I was developing from the start menu. And lo and behold this was the problem. I know this is still a beta framework and everything, but can the Windows team please throw us a bone and put in exceptions that actually mean something.
Just uninstall the application you are developing from the start menu.
