Techniques for enabling inter-subsystem resource sharing are provided. A subsystem executing an application (“app subsystem”) receives resources from another subsystem providing a resource (“resource subsystem”), such as a DLL. Then, when an application of the app subsystem is executed, the application may request a resource from the app subsystem, such as a DLL. The app subsystem, upon determining that the requested resource is associated with the resource subsystem, may communicate with the resource subsystem to request the resource. The resource subsystem may then load the resource. When the application utilizes the resource to perform an activity, such as by invoking a method of the DLL, the app subsystem may communicate with the resource subsystem to request the resource to perform the activity. The resource subsystem may provide an indication of a result to the resource subsystem upon completing the activity.
