Convert .Net WPF project into .Net Class Library

Working VB.Net WPF project that sends & receives serial port commands to be converted into Class Library - standalone DLL. Create Windows Form to call and send/receive commands thru it. To send serial port commands, 1. DLL is initialized 2. string passed to DLL with PortNumber As Integer, BaudeRate As Integer, mstime As Integer, CertPath As String, msg As String 3. DLL must set Set ASCII extended ascii like current projetc i.e. [login to view URL](28605) Private Async Function SendDTLSMsg(ByVal msg As String . . . . ) As Task [login to view URL](100) Dim SetExtEncoding As Object = [login to view URL] Dim response As String = Await [login to view URL](msg, CInt([login to view URL])) End Function 4. Response string passed back to Windows Form 5. Prove this works by using in real world application (use serial port end device) 6. Finally, add new DLL to another existing Windows Form Application and ensure code works
