// Setting the query language to "C# Statement(s)" permits multiple statements:

var words =
    from word in "The quick brown fox jumps over the lazy dog".Split()
    orderby word.ToUpper()
    select word;
    
var duplicates =
    from word in words
    group word.ToUpper() by word.ToUpper() into g
    where g.Count() > 1
    select new { g.Key, Count = g.Count() };    
    
// The Dump extension method writes out queries:

words.Dump();
duplicates.Dump();
