    So I have followed pretty much chapters 1 - 6 but I don't understand how a simple

    Evidence = Variable.Bernoulli(0.5);
using (Variable.If(Evidence))
{
	base.CreateModel();
}

    Is all that you need in the model to calculate evidence.  How does that C# capture my intension to calculate the evidence in such a simple statement.  Thanks.

    It works because the call to Variable.If sets a global flag so that when base.CreateModel executes, it knows that the model is inside of a Variable.If(Evidence) block.
