title: CSC : error CS7038: Failed to emit module
body: <p>After installing Visual Studio 2015 and building my project I receive the error</p>
  
  <blockquote>
    <p>"CSC : error CS7038: Failed to emit module". </p>
  </blockquote>
  
  <p>However my solution is building fine in Visual Studio 2013.</p>
  
  <p>It is an ASP.NET webforms project .NET 4.0</p>
  
  <p>Anyone?</p>
  
  <p><strong>UPDATE:</strong> it looks like the problem has to do with Red Gate Smart Assembly in combination with method parameters with default values.</p>
  
  <p><strong>UPDATE:</strong> Smart Assembly 6.9 fixes the error for me.</p>
