Register DelimiterAutoCompleter on DotNetSyntaxLanguage?

I was trying to disable the auto completion of curly brace and found few post talking about this line :

syntaxEditor.Document.Language.RegisterDelimiterAutoCompleter(new DelimiterAutoCompleter()
{
   CanCompleteAngleBraces = true,
   CanCompleteCurlyBraces = false,
   CanCompleteDoubleQuotes = true,
   CanCompleteParentheses = true,
   CanCompleteSingleQuotes = false,
   CanCompleteSquareBraces = true
});

 Unfortunately, i cannot find the method RegisterDelimiterAutoCompleter on both VBSyntaxLanguage and CSharpSyntaxLanguage.

I tried to register it as a Service, but it didn't work. Could someone help me achieve this?

Thank you!
