How can I search the Version of the application from app.config in c#?
<p>The code for app.config is as below:</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8" ?&gt;
&lt;configuration&gt;
  &lt;connectionStrings&gt;
    &lt;add name="conString" connectionString="Server= localhost;Database=OrderDetails;User Id=sa;Password=test;Trusted_Connection=false" /&gt;
  &lt;/connectionStrings&gt;
  &lt;system.web&gt;
    &lt;membership defaultProvider="ClientAuthenticationMembershipProvider"&gt;
      &lt;providers&gt;
        &lt;add name="ClientAuthenticationMembershipProvider"
             type="System.Web.ClientServices.Providers.ClientFormsAuthenticationMembershipProvider, 
             System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
             serviceUri="" /&gt;
      &lt;/providers&gt;
    &lt;/membership&gt;
    &lt;roleManager defaultProvider="ClientRoleProvider" enabled="true"&gt;
      &lt;providers&gt;
        &lt;add name="ClientRoleProvider" type="System.Web.ClientServices.Providers.ClientRoleProvider,
             System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
             serviceUri="" cacheTimeout="86400" /&gt;
      &lt;/providers&gt;
    &lt;/roleManager&gt;
  &lt;/system.web&gt;
&lt;/configuration&gt;
</code></pre>

<p>How can i retrieve the Version using C# i.e, 3.5.0.0 as you can see in <code>&lt;add&gt;</code> tag? Please help me.</p>
