title: MVC Unable to find Assembly
body: <p>I'm running into an issue after updating the assemblies in my project. Previously I deployed MVC application which contain a reference of an assembly named <code>Core.dll</code> (One of my class library project).</p>
  
  <p>Now in the newer version, I completely removed the dependency of <code>Core.dll</code> from my project and added new dependency <code>TrainingEngine.Core.dll</code> (new class library project).</p>
  
  <p>But the problem is after deployed my updated application, there are several errors being logged that says </p>
  
  <pre><code>Unable to find assembly 'Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.
  </code></pre>
  
  <p>And after further investigation, I came to know that this error raised from those users who previously had opened website on there browser and now when they refresh on there side, this error logged and the site is not responding to them. But if they delete there browser cache or use another browser, it works fine.</p>
  
  <p>I'm not sure why it still looking for old assembly even though I deployed new version. I restarted the App Pool, also Recycle it and restarted the web server but nothing help.</p>
  
  <p>Please suggest</p>
