Add the following namespace shortcut statements at the top of the file:
C#
using AuthoritExtensibility;
using API = Authorit.API;
VB
Imports Authoritextensibility
Imports API = Authorit.API
Implement the IPlugin interface:
C#
class PluginManager: IPlugin
{
...
VB
Public Class MergePluginManager
Implements IPlugin
...
