### Type of issue

Missing information

### Description

From anonymous feedback:

This page is rather abstract and does not give a very good feel for how this concept applies to calls to C# libraries, which is the main use for this feature. It would be very helpful if some example cases were added for calling C# code with Nullable arguments (int? etc). One example case is the Assert.AreEqual calls in the MSTest library, which had me stuck for several days until I asked for help on StackOverflow. I do suppose the information I wanted is here, but with no C# examples, a quick scan of the page did not lead me to realize this is the feature I needed to use.
