Abstract

Techniques for generating serialized view models that are used for both debugging an application and application support. The techniques include executing an application, creating a view model associated with the application, the view model including information associated with a service provided by the application, and presenting a user interface associated with the view model. The techniques can further include identifying, while presenting the user interface, an error occurring with the application, capturing a stack trace corresponding to the error, capturing a process image of the view model, serializing the process image of the view model to generate a serialized view model, and sending the stack trace and the serialized view model to a service. The service can then use the stack trace and the serialized view model to debug the application.
