A strategy is described for assisting a supplier in updating code without negatively impacting preexisting applications that may interact with the original or updated code. In this strategy, a resource is transferred from a first code module to a second code module. So that the applications that utilize the resource can continue to access this resource, the strategy adds forwarding information to a new version of the first code module. The forwarding information provides a note which shows the Common Language Runtime (CLR) where to find the specified resource when the code modules are executed.
