improve my => 'code' 
I just started playing around with LINQ seriously, and I really love some of the features incorporated, like the Enumerable.Range() function and how it can be used for integer programming.
Here's a simple function for generating lognormal distributions (could be useful for financial engineering).
Hope you're enjoying the samples,

public List<double> GenerateLogNormalDistribution(int numberOfTimes, double mean, double standardDeviation)
{
Random randomGenerator = new Random();
var randomNumbers = from theNumbers in Enumerable.Range(1,
numberOfTimes).Select(x => randomGenerator.Next(1,
1000)/1000.0)
select theNumbers;
List<double> results = new List<double>();
randomNumbers.ToList().ForEach
(x => results.Add(mean + (standardDeviation * (Math.Sqrt(-2 * Math.Log(x)) * Math.Cos(6.28 * x)))));
return results;
}
