title: Unable to debug .NET Core app
body: <p>I'm having and issue with Visual Studio and a .NET Core API project. It's been working fine but something must have changed because I'm now getting the following output when trying to debug the project:</p>
  
  <pre><code>The program '[18032] dotnet.exe' has exited with code -2147450749 (0x80008083).
  The program '[17688] iisexpress.exe' has exited with code 0 (0x0).
  The program '[5500] iexplore.exe' has exited with code -1 (0xffffffff).
  </code></pre>
  
  <p>The event viewer is showing this error:</p>
  
  <pre><code>Failed to start process with commandline '"C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\Microsoft\Web Tools\ProjectSystem\VSIISExeLauncher.exe" -debug -p "C:\Program Files (x86)\dotnet\dotnet.exe" -a "C:\Projects\Utilities\API\src\API\bin\Debug\netcoreapp1.0\API.dll" -pidFile "C:\Users\username\AppData\Local\Temp\tmp742C.tmp" -wd "C:\BlueSky\Utilities\API\src\API"', ErrorCode = '0x80004005'.
  </code></pre>
  
  <p>I'm not sure why this is happening, if anyone has any insight into this it would be appreciated.</p>
