I have a managed application compiled on .net 1.1 calling a unmanaged ACtive
X control which in turn uses a managed extension C++ COM dll compiled on .
Net 2.0. This causes the following exception to be generated in the managed
app

System.IO.FileLoadException

Common Language Runtime Internal error: 0x80131107

This results due to the a lower version CLR version already loaded in to the
managed applciations process. This situation can be rectified by changing
the application configuration file (supportedRuntime element) to specify
that the 2.0 .Net framework CLR should be loaded. The problem is that the
Active X control is used by many  other applications and it is not feasible
to update the app config file each time the Active X control is moved to a
higher version of the framework. Is there any way to specify which version
of a managed COM component should be loaded for a particular version of the
CLR. Any other solution to this problem.
