I need to do this, because sometimes the question is sent via email or SMS and the application has a timeout period for some of the questions. The user may also have answered the question from another UI connected to the app. At the moment all I can do is to try and handl ...Show All

Do you know an easy way to find out what programs use a particular GAC assembly I am afraid I would have to write a program that would scan every program on my computer and check its manifest to see what its dependencies were. Is this the best I can do Or maybe there is a convenient registry key that contains this inform ...Show All
