title: VSTS build Specflow error have 3.0 installed but it is trying to use 1.9
body: <p>I have written a feature file in my selenium C# framework
  I have Specflow 3.0 installed when I build my project I get the error:</p>
  
  <pre><code>#error: 'Version conflict - SpecFlow Visual Studio extension attempted to use SpecFlow code-behind generator 1.9, but project 'Test' references SpecFlow 3.0.' D:\Selenium Projects\CompanyName\Tests\\Login.feature.cs 1 Active
  </code></pre>
  
  <p>Why is it trying to reference version 1.9 I have only installed version 3.0.213</p>
  
  <p>How do I resolve this please?</p>
  
  <p>I have unloaded the project and searched for 1.9 in the csproj file.  There is no reference to 1.9</p>
