title: does .Net 4.5 include .Net 4.0
body: <p>I am developing a C# desktop application using Winforms. I created an installation strategy using visual studios click once installation tool. Luckily it provides clients to detect, download and setup the related prerequisite components.   </p>
  
  <p>My question is I started to develop this app with .NET 4.0 and then upgraded it to .NET 4.5 now on the prerequisites list both 4.5 and 4 is checked. i am wondering if i uncheck the .NET 4.0 component would it be alright? </p>
  
  <p>does .NET 4.5 include .NET 4.0?</p>
