[MonoDevelop] "Creating a Simple Addin"

[Vasili I. Galchin]

Hello,

      I am practicing with Monodevelop's (Mono's??) ability to
implement addins over extention points:
/home/vasili/Documents/MonodevelopCreating_a_Simple_Add-in.html. I
have higher goals that this exercise ;^). In any case, when I restart
monodevelop after moving the MonoDevelop.Samples.DateInserter.dll into
 ~/.config/MonoDevelop/addins/ , I get a load-time/run-time
errors/warnings:

WARNING: The add-in 'MonoDevelop.Samples.DateInserter,2.0' is trying
to extend '/MonoDevelop/Ide/Commands/Edit', but there isn't any add-in
defining this extension point

Why??
