Something is not working with my references

Question

im very new to Latex, and im now trying to make references work. It just doesnt work! I dont know what im doing wring, so in desperation I simply downloaded this https://www.overleaf.com/project/5c8ac946c46f07759d00e065 and compiled it, and i saw no reference (the online compiler in overleaf shows very pretty referencejust as its supposed to)! So i think the reason is some missing package in miktex. I use texmaker and miktex

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}

\usepackage[
backend=biber,
style=alphabetic,
sorting=ynt
]{biblatex}

\addbibresource{sample.bib}

\title{Bibliography management: \texttt{biblatex} package}
\author{Share\LaTeX}
\date{ }

\begin{document}

\maketitle

\tableofcontents

\section{First section}

Using \texttt{biblatex} you can display bibliography divided into sections, depending of citation type. 
Let's cite! Einstein's journal paper \cite{einstein} and the Dirac's book \cite{dirac} are physics related items. 
Next, \textit{The \LaTeX\ Companion} book \cite{latexcompanion}, the Donald Knuth's website \cite{knuthwebsite}, \textit{The Comprehensive Tex Archive Network} (CTAN) \cite{ctan} are \LaTeX\ related items; but the others Donald Knuth's items \cite{knuth-fa,knuth-acp} are dedicated to programming.
