//Simple Benchmark test for working with Strings in different versions of .NET Framework

string test = "Lorem Ipsum is simply dummy text" +
    " of the printing and typesetting industry. " +
    "Lorem Ipsum has been the industry's " +
    "standard dummy text ever since the 1500s, " +
    "when an unknown printer took a galley " +
    "of type and scrambled it to make a type specimen book. " +
    "It has survived not only " +
    "five centuries, but also the leap into electronic typesetting," +
    " remaining essentially unchanged." +
    " It was popularised in the 1960s with the release" +
    " of Letraset sheets containing Lorem Ipsum passages," +
    " and more recently with desktop publishing software like " +
    "Aldus PageMaker including versions of Lorem Ipsum.";
