We use application config file, i.e. developer will add enteries for their plugin's under specified well known section in the config file.
We don't use this techinque for the requirement you are looking for, but we use it for ISAPI filter plugin's. >From: Shawn Van Ness <[EMAIL PROTECTED]> >Reply-To: "Moderated discussion of advanced .NET topics." ><[EMAIL PROTECTED]> >To: [EMAIL PROTECTED] >Subject: [ADVANCED-DOTNET] Component Categories for .NET? >Date: Sun, 7 Apr 2002 10:23:59 -0700 > >Back in the days of COM, I used to enjoy building "plugin" architectures... >You know: design an interface (plus maybe an implementation or two), >publish it, and allow other devs to integrate their alternate >implementations with my app, at run-time. > >I was a big fan of CLSID_StdComponentCategoriesMgr, for this reason. > >Sure, it didn't really do anything that I couldn't have done myself -- say, >by dictating that all plugin authors register their components' CLSIDs >under "HKLM/SOFTWARE/My App/Plugins", or whatever. > >But it felt comforting and wholesome to have a standard, sanctioned way to >implement this pattern.
