Deprecated: get_product is deprecated since version 3.0!

Can you please look into this for me?

global $product;
        $product = wc_get_product(get_the_ID());
        if ( $product->is_type( 'simple' ) ) {
            echo get_woocommerce_currency_symbol(); echo "<a href='".$product->add_to_cart_url()."'><button id='simple_add_to_cart'>add to cart</button></a>";

I’m using wc_get_product, right? I can’t seem to get this error off.
Yes, debug option is on.
