dynamic, too. For example, variables can be declared to be
dynamic, and they can appear as types for members and their parameters. Yes, even generic parameters can be using
One of the first things we should look at is the effect of using some dynamically typed expression in a larger expression. To make this more concrete, look at the following example. A multiplication of a dynamically typed object with a statically typed object is made:
dynamic a = 3;int b = 5;var c = a * b;
The obvious question is what the inferred static type for
c will be. Recall that all ...
