处理启动/初始化VB .Net控制台应用程序中的异常(pre-Main(...))

是否有可能在VB .Net控制台应用程序中捕获启动/初始化异常(即在Main(...)运行之前)?

有许多解决方案在Main中为Thread和Unhandled异常添加处理程序,但是在Main运行时,捕获启动/初始化异常为时已晚。

例如,是否可以捕获此异常:

Module Module1
    Private Class BrokenClass                   'Constructor is broken/misconfigured;  throws exception
        Public Sub New()
            Throw New Exception("I Crashed!")   'Emulate constructor crash
        End Sub
    End Class
    '---------------------------------------------------------------------------------------------------
    Dim obj As BrokenClass = New BrokenClass()  'Assignment causes constructor exception
    '---------------------------------------------------------------------------------------------------
    Sub Main(ByVal args As String())            'Main hasn't run yet.  No chance to assign handlers.
        Console.WriteLine("Main Running...Press ENTER to exit")
        Console.ReadLine()
    End Sub
End Module

(我为色彩错误道歉;显然VB在代码块中没有正确着色)
