Managing Access to an Application

Disclosed are new approaches for building an application for a specific platform. Source code files may be compiled to an intermediate module and transmitted to a build server along with metadata describing a target operating environment. The build server selects an application template including an application shell suitable for the target operating environment. The application shell may be bound to the intermediate module by modifying the application shell to verify a signature of the intermediate module prior to executing it. The application shell may include a binary executable for executing the intermediate module in the target environment. Also disclosed is an approach for providing access to an application on a subscription or trial basis.
