We already discussed in detail how call sites are built, but we haven’t yet discussed how the invocation of the dynamic operation is initiated. In the code that was generated for our running example, the dispatch can be found at the end:

This code might look a little overwhelming at first, so let’s abbreviate it a little by using simpler names for the call site objects retrieved from the site container. Recall that the first site corresponds to the WriteLine call, and the second takes ...
