The compiler follows the spec here:

https://github.com/dotnet/csharplang/blob/main/spec/classes.md#instance-field-initialization

A variable initializer for an instance field cannot reference the instance being created. Thus, it is a compile-time error to reference this in a variable initializer, as it is a compile-time error for a variable initializer to reference any instance member through a simple_name.
