As soon as some users will create their own plugins based on a specific application version their might run into problems at the time they update the application but do not recompile their own plugins. Using the VersionedPluginManager to load the plugins into your application you have control which version you will accept or not.
Load all plugins which implements the “ISamplePlugin” from assembly version 1.0 to 1.9.3 from the current directory. An exception will be thrown if an incompatible version was found.
var pm = new PluginManager(Environment.CurrentDirectory) .Register<ISamplePlugin>(new Version(1, 0), new Version(1, 9, 3)) .Discover();
Same as above but without throwing an exception but calling the event “PluginIncompatibleVersionEvent” for each incompatible version.
var pm = new PluginManager(Environment.CurrentDirectory) .Register<ISamplePlugin>(new Version(1, 0), new Version(1, 9, 3)); pm.OnPluginIncompatibleVersion += new Events.PluginIncompatibleVersionEvent(pm_OnPluginIncompatibleVersion); pm.Discover(false); // do not throw an axception
