title: ASP.NET 5, DNX & Kestrel: Not hitting breakpoints
body: <p>Breakpoints are not being hit when debugging our DNX projects referenced in a ASP.NET 5 API project hosted with Kestrel (all in the same solution and in the src folder).  Debugging with IIS Express works fine.</p>
  
  <p><strong>What troubleshooting steps can be taken to solve this problem?</strong> </p>
  
  <p>No binaries or PDBs are created with DNX projects when debugging, so I am very unsure as to where to start.</p>
  
  <p><strong>project.json commands:</strong></p>
  
  <pre><code>"commands": {
    "web": "Microsoft.AspNet.Server.Kestrel"
  },
  </code></pre>
  
  <p><strong>Project properties:</strong></p>

  <p><strong>Note:</strong> Using the RC1 <code>1.0.0-rc1-final</code> libraries in all projects. </p>
  
  <h2><strong>EDIT:</strong></h2>
  
  <ul>
  <li>Breakpoints in the Startup.cs project are hit just fine, but not in other projects.</li>
  <li>I have double checked and reinstalled the <code>1.0.0-rc1-update1</code> DNX runtime. I have uninstalled all other runtimes.</li>
  <li>I have confirmed that PATH reflects the DNX runtime correctly.</li>
  <li>I have deleted all <code>project.lock.json</code> files and DNU restored.</li>
  <li>The actual breakpoint pin is red and doesn't indicate that there should be any problem.</li>
  <li><p>global.json is using the correct runtime:</p>
  
  <pre><code>{
    "projects": [ "src", "test", "." ],
    "sdk": {
        "version": "1.0.0-rc1-update1",
        "runtime": "clr",
        "architecture": "x86"
    }
  }
  </code></pre></li>
  </ul>
  
  <h2><strong>EDIT 2:</strong></h2>
  
  <p>In the Modules window, I can see that the projects' symbols aren't loading:</p>

  <p>How can I fix this?</p>
  
  <h2><strong>EDIT 3:</strong></h2>
  
  <p>I found that this problem <strong>only occurs when running multiple startup projects at the same time</strong>. When running a single project, debugging works just fine in all projects within the solution.</p>

  <p>I have no idea how to fix this and why it is happening.</p>
