We learned about how the events are implemented inside an interface. we learned about .NET Enum type (Enumerator): Enums expose a list of const values. they are actually integer numbers “behind the scenes”. we saw a variety set of Enum api functions which we can use, such as: Parse, GetValues, etc. We saw the Flags attribute which is used to define the Enum as a multi-selection Enum (using binary 1 and 0). we can use methods like HasFlags and pipe ( | ) operator in order to read and write values of the flag Enum instance
