C# OpenXml corrupt file

Question

I create a document as shown in the code below. That works fine. But when I try to open it, the application "Open Office" says it is corrupt and the application "File Viewer Lite" says "Error in text filter: Unknown format.". (A small app called "Doc Viewer" can open it.)

Any idea what is wrong?

Thank you.

public void Test_CreateDocument()
{
    MemoryStream objMemoryStream = null;
    WordprocessingDocument objWPDoc = null;
    MainDocumentPart objMDPart = null;
    Body objBody = null;
    try
    {
        using (objMemoryStream = new MemoryStream())
        {
            using (objWPDoc = WordprocessingDocument.Create(objMemoryStream, WordprocessingDocumentType.MacroEnabledDocument, true))
            {
                objMDPart = objWPDoc.AddMainDocumentPart();
                new Document(new Body()).Save(objMDPart);
                objBody = objMDPart.Document.Body;
                objBody.Append(new Paragraph(new Run(new DocumentFormat.OpenXml.Wordprocessing.Text("1Hello World!"))));
            }
            objWPDoc = null;
            using (var fileStream = new FileStream(this.txbWordDocument.Text, FileMode.Create, FileAccess.Write))
            {
                objMemoryStream.Position = 0;
                objMemoryStream.CopyTo(fileStream);
            }
        }
        objMemoryStream = null;
    }
    catch (System.Exception Ex)
    {
        MessageBox.Show(Ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);

    }
}
