None.

Notes:

The IServiceProvider defined here is different with "System.IServiceProvider". To remove name collisition, rename "IServiceProvider" to other name such as "UCOMIServiceProvider". Otherwise, you should use fully qualified namespace to the interface since you will normally use "using System" directive.
