VSTA Editor and DLL building issues

Hello,
I use VSTA editor from Corel X5
Visual studio 2019 installed
I Build AddIn3.dll and place in necessary CorelDraw AddIns folder. 

In AddIn3.dll i put code for Main.vb

<System.AddIn.AddIn("My Add-in", Version:="1.0", Publisher:="", Description:="")> _
Partial Class Main
WithEvents app As Application

Private Sub Main_Startup(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Startup
app = CType(Me.Host, Application)
MsgBox("COREL VSTA CREATED" & Chr(13) & "START" & Chr(13) & "G:\ONEDRIVE\Documents\Corel\VSTA\CorelDRAW\Addins\AddIn3.dll")
End Sub

Private Sub Main_Shutdown(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Shutdown
MsgBox("COREL VSTA CREATED" & Chr(13) & "END" & Chr(13) & "G:\ONEDRIVE\Documents\Corel\VSTA\CorelDRAW\Addins\AddIn3.dll")
End Sub

Private Sub app_DocumentNew(ByVal Doc As Corel.Interop.CorelDRAW.Document, ByVal FromTemplate As Boolean, ByVal Template As String, ByVal IncludeGraphics As Boolean) Handles app.DocumentNew
MsgBox("COREL VSTA CREATED" & Chr(13) & "DOCUMENT NEW" & Chr(13) & "G:\ONEDRIVE\Documents\Corel\VSTA\CorelDRAW\Addins\AddIn3.dll")
End Sub
End Class

All code above worked well for events Startup, Shutdown, DocumentNew

In Module1.vb i put 

Public Sub AddIn3Proba2()
     MsgBox("OK")
End Sub

Then in VBE of Globalmacros.gms in module CorelMacros i put
Public Declare Sub AddIn3proba2 Lib "G:\ONEDRIVE\Documents\Corel\VSTA\CorelDRAW\Addins\AddIn3.dll" ()
Sub just_created_macro2()
AddIn3proba2
End Sub
And when start just_created_macro2 Error message appeared:

Can't find DLL entry point AddIN3proba2 in G:\ONEDRIVE\Documents\Corel\VSTA\CorelDRAW\Addins\AddIn3.dll


My question is related with above information: How to add Sub or Function to AddIn3.dll, where document events work well, but no Function or Sub. I can not create any worked Sub or Function in this project. I create, but they not work and the above error message appears.

Please help!
Greetings!
