You will still need to do a little coding too:

  1. Define your normal distribution.
  2. Sample from it.

N.B You need to define it once and then sample as opposed to re-define.

Maybe this little class can help, then you can just use it in your code where you need...

    public class BoxMullerNormal
        {                       
            private MathNet.Numerics.Distributions.Normal normal;

            public BoxMullerNormal(double mean = 0,double std = .01)
            {
                normal = new MathNet.Numerics.Distributions.Normal(mean,std);            
            }

            public override dynamic getRandom()
            {
                // Implementation Uses C#MathNet.Numerics Normal Distribution Sampling
                return normal.Sample();                          
            }
}

Initialize the class at the start of your app to define the normal, then just call getRandom() every time to sample from it. You can also add the class to once of your existing Interfaces.
