Symptom: You get the following pop-up message that prompts you to check your application configuration:“The request could not be performed because required configuration settings are missing. Please contact your administrator to fetch the latest configurations files”.
Solution: This issue occurs due to the presence of multiple App.config files in the solution. The App.config that holds all the required configuration for a GWM based solution to work is stored inside the SAP Service Reference folder under the project file. For running a GWM based solution you need to either have only one App.config file, or specifically load the GWM config file as and when needed.
