I am a beginner when it comes to Latex. I am using MikTex TexWorks on Windows. I have already seen this post
However it seems I am still missing something when it comes to Biblatex approach and that's what I am specifically interested in.
Here's my simple code .tex file
\documentclass[11pt,a4paper]{article}
\usepackage{multicol}
\usepackage[style=alphabetic]{biblatex}
\addbibresource{myref}
\DeclareNameAlias{default}{first-last}
\begin{document}
This is a sample document. This is a sample document.
This is a sample document ~\cite{Ref1}. This is a sample document. \\
\printbibliography
\end{document}
and my myref.bib file in the same folder is
@Article{Ref1,
author = {First, Last},
title = {Sample Article},
journal = {Journal 1},
year = {2006}
}
For @Article I believe these are a must to be included.
In MikTex it runs without any errors and generates the PDF, but reference is missing.
This is the PDF output. I am wondering where am I making a mistake. I am a beginner and am learning by following other examples already available.
