title: How to include multiple source files in C#
body: <p>I am trying to learn C# coming from a C++ background, but I cannot figure out how to link two source files together.  I have a relatively simple program called test.cs and a main.cs.  All I want to do is in main.cs say:<br>
      <code>#include &lt;"test.cs"&gt;</code>.</p>
  
  <p>The closest I've been able to come up with is:  </p>
  
  <pre><code>&lt;Compile Include="test.cs"/Compile&gt;
  </code></pre>
  
  <p>However the compiler does not recognize this. So how can I include multiple source files in my main?</p>
