Method overloading with dynamic data types

Question

Why compiler is restraining to overload method in below way, Compilation Error i get in update method with dynamic type parameter.

Error - Type 'Program' already defines a member called 'update' with the same parameter types

static void update(string name)
    {

    }
static void update(object name)
    {

    }

static void update(dynamic name)
    {

    }

Answer 1

Because dynamic is also a type of object. You can check the generated IL code. So its giving compilation error for

static void update(object name)
    {

    }

static void update(dynamic name)
    {

    }
