With .NET’s XML serialization, it kills newlines when you serialize XML to disk. More specifically, it converts a CR+LF into just an LF (\r\n becomes just \n).

This was causing annoyances with the spell editor, since you can edit source code for spells with it, but the code would appear all on one line after saving and reloading.

The fix was to declare XmlWriterSettings with a newline preference.

The code was this:

         public void Save()
         {
             XmlSerializer serializer = new XmlSerializer(GetType());
             Stream stream = new FileStream(FileLocation.SpellDirectory + FileName,
                 FileMode.Create, FileAccess.Write, FileShare.None);
             serializer.Serialize(stream, this);
             stream.Close();
         } 

And now it’s this:

        public void Save()
        {
            XmlWriterSettings ws = new XmlWriterSettings();
            ws.NewLineHandling = NewLineHandling.Entitize;
            XmlSerializer serializer = new XmlSerializer(GetType());
            Stream stream = new FileStream(FileLocation.SpellDirectory + FileName,
                FileMode.Create, FileAccess.Write, FileShare.None);
            XmlWriter writer = XmlWriter.Create(stream, ws);
            serializer.Serialize(writer, this);
            stream.Close();
        }

I can have my newlines and eat them too. Oh joy!
