Error parsing { foo: &foo bar }

var scanner = new Scanner(new StringReader("{ foo: &foo bar }"));
var parser = new Parser(scanner);
while (parser.MoveNext()) {}

YamlDotNet.Core.SemanticErrorException : While parsing a flow mapping, did not find expected ',' or '}'.

   at YamlDotNet.Core.Parser.StateMachine()
   at YamlDotNet.Core.Parser.MoveNext()

However, this would be OK: { foo: &foo bar, }. Also this: { foo: bar }
