## Partial events and constructors

C# 14 rounds out the set of partial members by adding partial instance constructors and partial events. These new partial member types join partial methods and partial properties that were added in C# 13. Partial members allow one part of a class to declare a member, which can then be implemented in another part of the same class, often in a different file. Partial members are often used by source generators.
