问题 I'm writing a web application that will have "plugins". The plugins will be .DLL files which will export their functionality through predefined interfaces 'n stuff. All the .DLL files are in a folder called "Plugins", and the ASP.NET application loads them all upon startup (by using Assembly.LoadFrom).
