           Summary: WindowsFormsApplicationBase.OnCreateMainForm should not
                    throw exception
           Product: Mono: Class Libraries
           Version: 1.9.0
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Minor
          Priority: P5 - None
         Component: VB Runtime
        AssignedTo: rkvinge at novell.com

When deriving a new application class from
Microsoft.VisualBasic.ApplicationServices.WindowsFormApplicationBase, the
following code works on Microsoft .NET:

Public Class MyApplication
    Inherits
Microsoft.VisualBasic.ApplicationServices.WindowsFormApplicationBase

    Protected Overrides Sub OnCreateMainForm()
        MyBase.OnCreateMainForm()
        MainForm = New Form1()
    End Sub
End Class

However, on Mono, MyBase.OnCreateMainForm() throws a NotImplementedException.

Basically, it looks like on Microsoft's .NET
WindowsFormApplicationBase.OnCreateMainForm() does nothing (i.e. does not set
the main form and does not throw an exception), but
WindowsFormApplicationBase.Run() will throw an exception, after calling
OnCreateMainForm(), if MainForm is Nothing.

Obviously, this can be worked around by removing the unnecessary call to
MyBase.OnCreateMainForm().
