Error in AST when record is used as a variable name

Hi,

we noticed a problem with the C# parser when the keyword "record" is used as a variable name. The C# compiler does not seem to have an issue with this. But here this causes two issues. Firstly the outlining node ends abruptly at the keyword. Secondly the following methods are sometimes missing in the AST. Since we use the AST to generate files, these methods are then missing. Example:

public class test
{
  public static void a()
  {
    var record = "";
    record += "";
  }

  public static void b()
  {
  }
}
