WINDOWS PHONE 8.1 DEVELOPMENT (Create an XML Document) No file

Hi all,
I have been trying to figure out how to create an XML document.  I've found many code examples; but don't see where the file is specified in any of them.  Below is the code I have so far and have a file variable (string) but can't seem to fit it in anyplace.

Dim XMLDOC$ = txtSAFE_NAME.Text & ".xml"

        ' Create XmlWriterSettings.
        Dim settings As XmlWriterSettings = New XmlWriterSettings()
        settings.Indent = True
        Dim sw As New StringWriter()

        ' Create XmlWriter.
        Using writer As XmlWriter = XmlWriter.Create(sw, settings)
            writer.WriteStartElement("RUSAFE") ' Root.

            writer.WriteElementString("FILE_NAME", txtSAFE_NAME.Text.ToString)


            ' End document.


            Dim output As String = sw.ToString()

        End Using

You could try something like this, which uses the LINQ-to-XML XDocument:

Imports System.Xml.Linq

Public Class Test

	Public Shared Sub WriteXmlDocument(fileName As String)
		Dim document = New XDocument()

		Dim rootElement = 
                     New XElement("RUSAFE",
                          New XElement("INFOTBL", 
                             New XAttribute("FILE_NAME", txtSAFE_NAME.Text.ToString())))


	End Sub
End Class

Exact same problem.  When getting to the "filename" an error is presented that I have to use xmlwriter, stream or textwriter; but all have the same error. "Value of type string can not be converted"

Can you attach the full stack trace for the exception?

Ok, I got it to work with the help of some code I found and Bob's imput.

Dim XMLDOC$ = txtSAFE_NAME.Text & ".xml"
        Dim sf As Windows.Storage.StorageFolder = RSCatalog_Loc
        Dim st As StorageFile = Await sf.CreateFileAsync(XMLDOC$)

        Dim rootElement =
                     New XElement("SAFE",
                          New XElement("INFOTBL",
                             New XAttribute("FILE_NAME", txtSAFE_NAME.Text.ToString())),
                          New XElement("MAINTBL",
                             New XAttribute("SID", "124"),
                             New XAttribute("sITEM_NAME", "DOCUMENT 1"),
                             New XAttribute("SNOTES", "THIS IS A NOTE")))

        Await writeXml(rootElement, st)

Private Async Function writeXml(Of T)(Data As T, file As StorageFile) As Task
            Dim sw As New StringWriter()
            Dim xmlser As New XmlSerializer(GetType(T))
            xmlser.Serialize(sw, Data)

            Using fileStream As IRandomAccessStream = Await file.OpenAsync(FileAccessMode.ReadWrite)
                Using outputStream As IOutputStream = fileStream.GetOutputStreamAt(0)
                    Using dataWriter As New DataWriter(outputStream)
                        Await dataWriter.StoreAsync()
                    End Using

                    Await outputStream.FlushAsync()
                End Using

            End Using
        Catch e As Exception

            Throw New NotImplementedException(e.Message.ToString())
