In the Microsoft documentation for System.Xml, there is an example for IFragmentCapableXmlDictionaryWriter.WriteFragment at URL https://learn.microsoft.com/en-us/dotnet/api/system.xml.ifragmentcapablexmldictionarywriter.writefragment?view=net-8.0. When I implement that example, it always takes the path that leads to the WriteLine message "This writer doesn't support fragments." How can that example be rewritten to support fragment writing so I can see how it is actually supposed to work?
Probably the example is for .NET Framework.
Try another writer:
XmlDictionaryWriter writer = XmlDictionaryWriter.CreateBinaryWriter( stream );
If the example is for .NET Framework, I should report feedback to Microsoft on this since the example appears in a .NET 8.0 document.

Hi @Nicholas Piazza ,Have you tried .NET Framework? Are you talking about the following code?
MemoryStream stream = new MemoryStream();
MemoryStream fragmentStream = new MemoryStream();
XmlDictionaryWriter writer = XmlDictionaryWriter.CreateTextWriter(stream);
IXmlFragmentCapableXmlDictionaryWriter fragmentWriter = writer as IXmlFragmentCapableXmlDictionaryWriter;
if (fragmentWriter == null || !fragmentWriter.CanFragment)
{
Console.WriteLine("This writer doesn't support fragments");
return;
}
writer.WriteStartElement("Root");
fragmentWriter.StartFragment(fragmentStream, false);
writer.WriteStartElement("Body");
writer.WriteString("This is my body");
writer.WriteEndElement();
fragmentWriter.EndFragment();
writer.WriteStartElement("CharsInTheBody");
writer.WriteValue(fragmentStream.Length);
writer.WriteEndElement();
fragmentWriter.WriteFragment(fragmentStream.GetBuffer(), 0, (int)fragmentStream.Length);
writer.WriteEndElement(); // Root
Yes, that's the code I'm talking about. If that example only applies to .NET Framework, it should be removed from the .NET 8.0 (and 7.0) documentation.
