When Replace is called on empty string, it does not replace 
if pattern matches.

using System;
using System.Text.RegularExpressions;

class Example
{
   public static void Main()
   {
      string pattern = @".*";
      Regex rgx = new Regex(pattern);

      string inputStr = "";

      string outputStr = rgx.Replace(inputStr, "ok");

      Console.WriteLine(
          String.Format("Pattern:       \"{0}\"", pattern) + "\n"+
          String.Format("Input string:  \"{0}\"", inputStr) + "\n"+
          String.Format("Output string: \"{0}\"", outputStr) + "\n"
      );
   }
}

Result on MONO:

Pattern:       ".*"
Input string:  ""
Output string: ""

Result on Microsoft .NET:

Pattern:       ".*"
Input string:  ""
Output string: "ok"
