Open *.txt with file selector from vb console application

I need to use a console application. I would like a file selector to open so the user can select any .txt file. I have looked at OpenFileDialog but as far as I can see that only works for form applications.

This kind of window is what I was looking for:

this sort of thing

Like I said, you should not be using Windows-UI in Console Apps, that said, here's how you do it for your requirement.

I wrote it on my local machine and it works.

Create a new VB.Net Console Project, and Reference to System.Windows.Forms and paste this entire code in the module1.vb (P.S. I update it to include @Codexer's recommendation, and also included the error message in the exception handler.)

Imports System.Windows.Forms

Module Module1

    <STAThread()> _
    Sub Main()
        Dim OpenFileDlg as new OpenFileDialog

            OpenFileDlg.FileName = "" ' Default file name
            OpenFileDlg.DefaultExt = ".txt" ' Default file extension
            OpenFileDlg.Filter = "Text Files (*.txt)|*.TXT"
            OpenFileDlg.Multiselect = True
            OpenFileDlg.RestoreDirectory = True
            ' Show open file dialog box
            Dim result? As Boolean = OpenFileDlg.ShowDialog()

            ' Process open file dialog box results
    for each path in OpenFileDlg.Filenames
      Try
                             System.Diagnostics.Process.Start(Path)

            Catch ex As Exception
                MsgBox("Error loading the file" & vbCrLf & ex.Message)
            End Try
            If result = True Then
                ' Open document
            Else
                  Exit Sub
            End If
    next
    End Sub

End Module

Here's the output.
