 ## Init only setters
 
-***Init only setters*** provide consistent syntax to initialize members of an object. Property initializers provide make it clear which value is setting which property. The downside is that those properties must be settable. Starting with C# 9.0, you can create `init` accessors instead of `set` accessors for properties and indexers. Callers can use property initializer syntax to set these values in creation expressions, but those properties are readonly once construction has completed. Init only setters provide a window to change state. That window closes when the construction phase ends. The construction phase effectively ends after all initialization, including property initializers and with-expressions have completed.

 The preceding example for positional records demonstrates using an init-only setter to set a property using a with expression. You can declare init only setters in any type you write. For example, the following struct defines a weather observation structure:
