title: essential tools for .net programmer?
body: <p>This question looks familiar with this: <a href="https://stackoverflow.com/questions/2187/essential-programming-tools">https://stackoverflow.com/questions/2187/essential-programming-tools</a>, but I want to focus on .NET programming. Beyond Windows and Visual Studio, which tools are your daily-need to get your job done? Free, open-source code tools are preferred :) </p>
  
  <p>I've been using these tools:</p>
  
  <ul>
  <li>Resharper - top of its class, but not free</li>
  <li>NUnit - trying to get used with it.</li>
  <li>VisualSVN + TortoiseSVN</li>
  </ul>
  
  <p>which other tools I should know and use?</p>
