C# XDocument Save copy file and appends edited to end

When I'm trying to edit XML Element and save it, it generates copy (with edited element) and appends it to end of file.

var localStore = IsolatedStorageFile.GetUserStoreForApplication();

IsolatedStorageFileStream stream = new IsolatedStorageFileStream("DataFolder\\PlayerData.xml", FileMode.OpenOrCreate, FileAccess.ReadWrite, localStore);

var doc = XDocument.Load(stream);

doc.Root.Element("characters").Element("character").SetElementValue("expierence", 10);

doc.Save(stream, SaveOptions.None);
stream.Close();

Example output file:

<?xml version="1.0" encoding="utf-8"?>
<root>
    <characters>
        <character>
            <expierence>0</expierence>
        </character>
    </characters>
</root><?xml version="1.0" encoding="utf-8"?>
<root>
    <characters>
        <character>
            <expierence>10</expierence>
        </character>
    </characters>
</root>

That's exactly what you told it to do by passing FileMode.OpenOrCreate.
If you want to truncate any existing file, pass Create.

For more information, see the documentation.
