title: PlatformNotSupportedException: The following constructor parameters did not have matching fixture data
body: <p>I wrote some tests with dotnet core 2. This tests drive some Selenium's browsers. I developed the first test in local (using dotnet core 2.0 and xunit) and it workes like a charm.</p>
  
  <p>Then I moved the project into Azure DevOps pipeline and I get this error:</p>
  
  <blockquote>
    <p><strong>System.PlatformNotSupportedException</strong> : Operation is not supported on this platform.</p>
    
    <p>The following constructor parameters did not have matching fixture
    data</p>
  </blockquote>
  
  <p>It seemed like in local development (a simple VS Code editor) someone inject automatically a Fixture inside contructors like that:</p>
  
  <pre><code>public AConstructor(TestFixture tf)
  {
      this.tf = tf;
  }
  </code></pre>
  
  <p>so I roughly rewrite it as:</p>
  
  <pre><code>public AConstructor(TestFixture tf)
  {
      this.tf = new TestFixture();
  }
  </code></pre>
  
  <p>but the problem is still there and I have no idea of what the problem is. In local development we setted up Selenium Grid with Docker, using the same version of the real grid. In Azure DevOps pipeline we reused the sample command used in local environment.</p>
  
  <p>Any idea?</p>
