What's the error you see when calling the function in SimulationStep?

this is the test code..
-------------------------------
using MathNet.Numerics.Distributions;
void hello()
{
double[] samples = SystemRandomSource.Doubles(100, 90);
}

the above works, however:
----------------------------------
public void simulationStep()
{
double[] samples = SystemRandomSource.Doubles(100, 90);
}
