title: Unable to install or run the application. The application requires that assembly Microsoft.Practices.Prism.SharedInterfaces Version 1.1.1.0
body: <p>I'm deploying a WPF application using ClickOnce. The application runs fine on my machine from VS2012, but when I go to try to install it from ClickOnce, it shows the following error, which I understand is very common:</p>
  
  <p><a href="https://i.stack.imgur.com/s1Xgf.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/s1Xgf.png" alt="Error Shown"></a></p>
  
  <p>As I proceed to do further research, I REALLY cannot find why ClickOnce is asking for Prism.SharedInterfaces v1.1.1.0.</p>
  
  <p>Here are a few of the things I checked:</p>
  
  <p><a href="https://i.stack.imgur.com/rKC4i.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/rKC4i.png" alt="References and Properties of .dll inside VS"></a></p>
  
  <p>I followed the path to the physical file and made sure the version within the properties of the .dll is 1.0.0.0.</p>
  
  <p>I also opened the project solution file in notepad and looked for any sort of hidden reference that I could have missed. I've cleaned and rebuilt the solution a hundred times.</p>
  
  <p>When I publish, I make sure that the file is included in the Application files.</p>
  
  <p>Finally, I downloaded Process Explorer (which allows you to check what assemblies the application uses) and it still shows that SharedInterfaces.dll v1.0.0.0 is only being utilized.</p>
  
  <p>Nowhere can I see Microsoft.Practices.Prism.SharedInterfaces.dll v1.1.1.0 being referenced nor used. Why is ClickOnce asking for it?</p>
  
  <p>I also found that you can add the following code in your App.config file to force version use:</p>
  
  <pre><code>  &lt;dependentAssembly&gt;
      &lt;assemblyIdentity name="Microsoft.Practices.Prism.SharedInterfaces" publicKeyToken="31bf3856ad364e35" culture="neutral" /&gt;
      &lt;bindingRedirect oldVersion="0.0.0.0-1.1.1.0" newVersion="1.0.0.0" /&gt;
    &lt;/dependentAssembly&gt;
  </code></pre>
  
  <p>but no luck.. I've run out of ideas. Any help would be greatly appreciated.</p>
  
  <p>Thanks in advance!</p>
