Abstract: A method and system for dynamically identifying and loading a version of a runtime for custom code of a host application without modifying the host application is provided. A loading system dynamically identifies the version of the runtime during execution of the host application. The loading system is also dynamically linked into the host application so that its algorithm for identifying the version of the runtime can be modified without modifying the host application. When requested by the host application to load custom code, the loading system identifies a version of the runtime to load, loads the identified version of the runtime, and then requests a load component of the loaded version of the runtime to load the custom code.

Abstract: A method and architecture for increasing version resiliency between a host application that is unmanaged code and managed code is provided. A version resiliency technique specifies that the host application and the managed code communicate via an adapter that implements a protocol to access an object exposed by the host application. The version resiliency technique specifies that when a new version of the host application that impacts an interface exposed by the object of the host application is released, a new version of the adapter that executes within the application domain of the custom code is released. A version of managed code that adheres to the protocol will correctly interact with new versions of the host application that include a new version of the object because a new implementation of the adapter is also provided.

Abstract: A method and architecture for increasing version resiliency between a host application that is unmanaged code and custom code that is managed code is provided. A host application exposes an application-level object and a document-level object. A custom code runtime provides a wrapper for the document-level object within the application domain of the custom code runtime. The custom code runtime also provides a mechanism within the application domain of the custom code runtime for providing to custom code a reference to the application-level object directly, rather than through a wrapper. Custom code can then access functionality of the application-level object directly using the reference without having to use a wrapper provided by the custom code runtime.
