Windows Form Load event is not triggered.

Last Modified: 2017-11-20
I have an old mostly VB based  Windows application I have been trying to move from 32 bit systems (W2K & XP) to 64 bit systems (W7 & W10).  I am using VS2015 for this work and have the configuration set to "Any CPU".

The main form of this application inherits directly from System.Windows.Forms.Form.   When I start the application the main form's Load event handler is not called.  Other form events (e.g. Activate, Resize) are called, but as these rely on objects defined during the load event they raise appropriate null value exceptions.

I have set breakpoints in the Load event handler to confirm that it really is not being invoked.

My searches have so far yielded only results that pertain to conflicts with missing data bindings.  There are no data bindings used within this application.

Any ideas about what might cause this lack of a load event trigger will be greatly appreciated, as will suggestions about how I might further diagnose this problem.
