Primary Constructor:
Primary constructor parameters may not be stored if they aren't needed.
Primary constructor aren't members of the class. for example a PC parameter named param can't be accessed as this.param.
Primary Constructor paramere can be assigned to.
Primary Constructor parameters don't becomes properites, except in record types.
Collection Expression:
Inlining other collections into these values is possible using a spread operator ....
int[] row0 = [1, 2, 3];
int[] row1 = [4, 5, 6];
int[] row2 = [7, 8, 9];
int[] single = [.. row0, .. row1, .. row2];
Inline arrays:
Inline arrays are used by the runtime team and other library authors to improve performance in your apps. Inline arrays enable a developer to create an array of fixed size in a struct type.
A struct with an inline buffer should provide performance characteristics similar to an unsafe fixed size buffer.
