Build 300 'Member could be made static' suggestion for event handler methods
related to Windows Form Designer generated code is performing incomplete
code adjustments. It should be removing 'this' from the applicable Windows
Form Designer generated code sections when changing the method to static.
Of course, given that this section of code is maintained by the VS IDE and
there is no guarantee that the change will not be overwritten, should the
suggestion not be made in this instance?
