When you develop an extension, you can use the configuration setting in the swExplorer client to allow for configuration of which item types and attributes the extension should interact with.

Configure the explorer

To programmatically receive the XML configuration entered in Configure the explorer when the extension is initialized, use the following code: 

IswApplicationConfig config = _host.GetApplicationConfig();
string xml = config.ConfigXML("INSERT your GUID");

--Instead of "INSERT your GUID", you simply enter the GUID you have defined for you plugin.
