Which version of the .NET Framework is IIS using for my AppPool?
<p>.Net Framework 4.5 was installed on my machine and on the IIS Application Pool, I set the .NET CLR version to 4.0.</p>

<p>My question is when running .NET code in this IIS site, which framework version is it using: 4.0 or 4.5 ? </p>

<p>Please see below screen shots.</p>
