A computer with a platform that reduces cross-platform compatibility issues associated with executable computer components. A context for a component to be executed on a computer is detected. The context may be detected by searching metadata associated with the component and locating the context therein. If the context is not found in the metadata, then a context may be inferred in other ways, such as from a subsystem major/minor version. Execution of the component invokes one or more components of a computer operating system that provides a platform for executing operations that support execution of the component. Branch components present in the platform are used to select behaviors for the operations based at least in part on the detected context of the component. By providing a context-based selection from any of multiple targeted behaviors for an operation performed by the platform, cross-platform compatibility is improved.
