Answer 1

As your error message explicitly states :

The name 'UpdateControls' does not exist in the current context.

If you manually performed this migration, it's likely that you simply neglected to copy over your UpdateControls() method. You should consider double-checking through your updated Project to see if it is actually missing.

If it is included within the project, then ensure that it has the proper access modifiers and it is able to be accessed (ie in the proper namespace, etc.).
