title: All of sudden Specflow generator is throwing exception with Visual studio 2015.I have not upgraded any new package of Visual Studio or Specflow
body: <p>I am using Visual Studio 2015 and Specflow 2017.1..12. I have been using this combination for more than 2 years. Everything was fine until January 2018. </p>
  
  <p>We did not develop any new test in February 2018. As we did not get time to work on automation. I started working on new tests since last week and updating existing tests. When I modified existing specflow feature file and save it, the <code>feature.cs</code> file is not getting generated. It is throwing a generator exception. </p>
  
  <p>I am not sure why we are getting this exception all of sudden. We did not upgrade any Visual Studio or Specflow plugin for more than 1 year. </p>
  
  <p>I have been searching online for a solution, but I could find any answer. Please help!</p>
  
  <p>This is the generator exception:</p>
