When I try to deploy any SandBox Solution I receive following error:
Error occurred in deployment step 'Retract Solution': Timeout occurred while running the SharePoint Sandboxed Code service. This service is required to run sandboxed solutions in SharePoint. Please ensure the service is configured correctly in SharePoint.
Each time I try to deploy a SandBox solution,
SharePoint 2010 User Code Host Service stops.
Why it happen and how can I deploy a SandBox Solution?
