title: Migrating C# to VB code, getting "Must implement xxx"
body: <p>I am attempting to add a spellcheck control in my winforms application in VS 2012 (VB).  The project is here:  <a href="https://www.codeproject.com/Articles/73802/NHunspell-Component-for-Visual-Studio#Spelling%20control" rel="nofollow noreferrer">https://www.codeproject.com/Articles/73802/NHunspell-Component-for-Visual-Studio#Spelling%20control</a></p>
  
  <p>The test application is using C#, so I am trying to translate from C# to VB.  I am getting errors saying that I am not implementing various parts of the interface.  For example I'm I didn't implement Focus.  (see screenshot).  However these were not implemented in the c# testing application which I translated to VB.  So I am wondering if i am doing something wrong, do I need to change the interface somehow?</p>
