I had a cs degree, I knew c# and .net but I&rsquo;ve never built anything with it except few console and very small windows app. I was writing a code of uploading images and I needed to write the same image upload code in multiple places. It was fine when I&rsquo;ve copied it in 2 or 3 places, but I was getting annoyed when I had to copy it in multiple places. I did not bother to refactor it. Honestly, I didn&rsquo;t even know about refactoring. But in future, I had to update the code and I had to update the code in multiple places. Then I got to know about utility or helper methods. Later I learned that it is a concept called <code>DRY (Do not repeat yourself)</code>.</p>
