Error inside of Application.Designer.vb inside of OnCreateMainForm() Sub

Question

I can't figure out what the issue is here. I started project from scratch, went to debug, and received error:

System.InvalidOperationException was unhandled Message=An error occurred creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object.

I am not understand why this error is occurring in an auto-generated file. Here is the code in it's entirety:

    '------------------------------------------------------------------------------

'     This code was generated by a tool.
'     Runtime Version:4.0.30319.269

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

Error occurs at:

Me.MainForm = Global.AccountAndClientFull.frmMain

Any suggestions? I can't figure out what changes need to be made in the application tab of the project properties.

Answer 1

I got the same error and realized it was because I had declared a private default constructor in the form code. If you created a constructor and didn't make it public, try making it public.
