title: Can a post-build step take me to a specific line of code?
body: <p>I just wrote a little program which will be executed as a post-build step when I compile certain projects.</p>
  
  <p>This program returns 0 for success, or some number for failure. In case of failure, Visual Studio then correctly outputs: "The command [...] exited with code <em>n</em>."</p>
  
  <p>However, a single number is not always helpful. In my case, I actually want the error to point to a specific place in the source code. Is it possible to output a filename and line number in such a way that Visual Studio will actually let me just double-click on the error and get there instantly?</p>
