add "My" namespace to generated settings type

[adamint]

To fix https://devdiv.visualstudio.com/DevDiv/_workitems/edit/1589004?src=WorkItemMention&src-action=artifact_link, we need to add "My" namespace to the MySettings class.

This works for .net framework 4.8 VB, as well as .net core VB and .net core C#, but before approving it, another pair of eyes on the generated file would be nice

Was this always broken? I'm trying to think why this is breaking now if there haven't been significant changes in the last months/years to this code generator.

this may have been related to my most recent designer changes

works! caveat that System.Configuration.ConfigurationManager is a required package for .net core projects. we should consider adding a comment/automatically installing this package for users in the future @melytc
