In non-limiting examples of the present disclosure, systems, methods and devices for selectively virtualizing software application functions are presented. An application package for a containerized software application may be received. The application package may comprise an application manifest and a virtualization exclusion for a first location of a global file system of the computing device. The containerized software application may be installed in a container comprising a virtual file system. An indication to write a first new file at the first location may be received by the containerized software application. A determination may be made that the first location comprises the virtualization exclusion. The first new file may be written to the first location of the global file system based on the determination that the first location comprises the virtualization exclusion.

Flexible virtualization of application data for specified system locations

The operating system of a computer maintains an extension catalog that stores data relating extensions with information about the contracts the extensions support. Extensions are registered in this catalog according to the contract they implement. The extension catalog can be queried to identify extensions that support a given contract. An extension can be selected from among the results from a query, and the selected extension can be activated. When activated, the extension is set up by the operating system as an independent process from, and with context from, the application for which it is an extension. Information about the extension is provided to the application to enable the extension and the application to communicate according to the supported contract.

Discovery and activation of application extensions

An isolation execution environment provides an application with limited resources to execute an application. The application may require access to secured resources associated with a particular trust level that are outside of the isolation execution environment. A trust activation engine determines the trust level associated with a request for a resource and operates differently based on the trust level. A broker process may be used to execute components providing access to resources having a partial trust level in an execution environment that is separate from the isolation execution environment.

Trust level activation

Interface identifier parameterization techniques are described. In one or more implementations, a textual description is obtained of a parametric type represented in a binary standard of a programming model and an interface identifier is generated based at least in part on the obtained textual description of the parametric type.
