Assignment to readonly property in initializer list

Question

Can one tell me, why the heck does it compile?

namespace ManagedConsoleSketchbook
{
    public interface IMyInterface
    {
        int IntfProp
        {
           


        

Answer 1

Because

int IntfProp {
    get;
    set;
}

is not readonly.

You did not invoke setter of MyClass.Property, just getter.
