title: Missing Microsoft.Data.Tools.Schema.Sql.UnitTesting. Again
body: <p>The bug is very old but MS didn't fix it so far.</p>
  
  <p>I had a VS2015 solution (many projects, with main ASP.NET one) and I opened it in VS 2017.</p>
  
  <p>Here is what I saw when I tried to build it:</p>

  <p>So, I figured, okay, some referenced broke, I went into Project References, removed those two (...Sql.UnitTesting and ...Tools.Components), and tried to add them back. What did I saw? Of course, this:</p>
  
  <p><img src="https://i.snag.gy/vUA6OF.jpg" alt=""></p>
  
  <p>The version is wrong, its <strong>15.1.0.0</strong> instead of previous <strong>15.0.0.0</strong> (for both DLLs). Big deal, you say, but it still doesn't compile:</p>
  
  <p><img src="https://i.snag.gy/LBqHhj.jpg" alt=""></p>
  
  <p>It tells me that the versions are mismatched and I have to create some assembly-bindings in the web.config file. <strong>Which I did</strong>, first manually, then via the double-click on the warning, as it suggested. <strong>Nothing changed</strong>. I still can't get my project build.</p>
  
  <p>Previous SO questions (<a href="https://stackoverflow.com/questions/16670211/automatic-reference-to-microsoft-data-tools-schema-sql-unittesting">Automatic reference to Microsoft.Data.Tools.Schema.Sql.UnitTesting</a>, <a href="https://stackoverflow.com/questions/3293317/where-is-the-microsoft-visualstudio-testtools-unittesting-namespace-on-vs2010">Where is the Microsoft.VisualStudio.TestTools.UnitTesting namespace on VS2010?</a>) don't help much, I cannot remove SSDT component, as it breaks the loading of the web-project completely. And my project <strong>isn't</strong> any sort of SQL Testing project. It is just a regular ASP.NET 4 web app.</p>
  
  <p>What can I do to fix this?</p>
