title: SpecFlow doesn't work on local machine; get a '*.feature.cs' could not be found
body: <p>I am trying to set up a hello world project SpecFlow but I cannot seem to build and run the tests for my project. I have even sent my .sln to a colleague and it builds and runs perfectly on his machine.</p>
  
  <p>We are both using Visual Studio 2019; I followed the 'Getting Started' page on spec flow website; I have 'Enable SpecFlowSingleFileGenerator' set to False. I have the extension installed for Visual Studio 2019.</p>
  
  <p>Example files: <a href="https://github.com/SpecFlowOSS/SpecFlow-Examples" rel="nofollow noreferrer">https://github.com/SpecFlowOSS/SpecFlow-Examples</a></p>
  
  <p>When I go to build I get the following in the *.feature.cs file:</p>
  
  <pre><code>#error Could not find a reference to SpecFlow in project 'MyProject.Specs'.
  #error Please add the 'TechTalk.SpecFlow' package to the project and use MSBuild generation instead of using SpecFlowSingleFileGenerator.
  #error For more information see https://specflow.org/documentation/Generate-Tests-from-MsBuild/
  </code></pre>
  
  <p>Any ideas? </p>
