我无法弄清楚这里的问题是什么。我从头开始项目,去调试,并收到错误:
System.InvalidOperationException 未处理 Message=创建表单时出错。有关详细信息,请参阅 Exception.InnerException。错误是:对象引用未设置为对象的实例。
我不明白为什么在自动生成的文件中会发生此错误。这是完整的代码:

Partial Friend Class MyApplication

MyBase.New(Global.Microsoft.VisualBasic.ApplicationServices.AuthenticationMode.Windows)
Me.IsSingleInstance = false
Me.EnableVisualStyles = true

Me.ShutDownStyle = Global.Microsoft.VisualBasic.ApplicationServices.ShutdownMode.AfterMainFormCloses
End Sub
<Global.System.Diagnostics.DebuggerStepThroughAttribute()> _
Protected Overrides Sub OnCreateMainForm()
Me.MainForm = Global.AccountAndClientFull.frmMain 'HERE IS WHERE THE ERROR OCCURS
End Sub
End Class
End Namespace
错误发生在:
Me.MainForm = Global.AccountAndClientFull.frmMain
有什么建议么?我无法弄清楚需要在项目属性的应用程序选项卡中进行哪些更改。
