There are 16 errors in the program :o

Your programm starts at 98 should start at 99 =)

There are not 16 errors in the program - use .NET 3.5 *final*, build as a console app.

It doesn't start at 98 - the default command window doesn't have a buffer large enough to show 99. You'll see 98 first only if you don't adjust your buffer height beyond 300 rows.

The line:
(n == 2 ? "1 bottle" : n.ToString() + " bottles"),
should read:
(n == 2 ? "1 bottle" : (n - 1).ToString() + " bottles"),

It's also probably benificial to move the .Reverse() up to the Enumerable such that it reads:
(from n in Enumerable.Range(0, 100).Reverse()
as reversing the integers seems cheaper than reversing the objects. Though that's just intuition and I could be wrong.

Also, I tend to prefer using:
Console.ReadKey(true);
to
Console.ReadLine();

No one Cares what you prefer to use. Dumbass.

StringBuilder beerLyric = new StringBuilder();

var beers =
(from n in Enumerable.Range(0, 100)
select new
{
Say = n == 0 ? "No more bottles" :
(n == 1 ? "1 bottle" : n.ToString() + " bottles",
Next = n == 1 ? "no more bottles" :
(n == 0 ? "99 bottles" :
(n == 2 ? "1 bottle" : (n-1).ToString() + " bottles"),
Action = n == 0 ? "Go to the store and buy some more" :
"Take one down and pass it around"
}).Reverse();

foreach (var beer in beers)
{
beerLyric.AppendFormat("{0} of beer on the wall.\n{1}, {2} of beer on the wall.\n\n",
beer.Say, beer.Action, beer.Next);
}

Console.WriteLine(beerLyric.ToString());
Console.ReadKey(true);
