title: Azure function build not generating function.json
body: <p>I have an azure function that was working perfectly this morning (was published on Azure).
  I had to add some logging functionality in Azure Storage and suddently I cannot run my function anymore. I have not tried to publish it as it does not run locally.</p>
  
  <p>The symptom is that I get the following exception:</p>
  
  <blockquote>
    <p>System.IO.FileNotFoundException: 'Could not find file
    'C:\projects\MySuperFunction\MySuperFunction\bin\Debug\netstandard2.0\bin\function.json'.'</p>
  </blockquote>
  
  <p>I read that thtis file is supposed to be generated at build time but I can confirm that the file is not there at all.</p>
  
  <p>The only modifications I made to the project was to add a reference to the WindowsAzure.Storage nuget package (v9.2.0)</p>
  
  <p>Does anyone knows why it is failing now while it was not before and, ideally, how to get it back working?</p>
