title: visual studio 2010 and entity framework 5.0, can I use it?
body: <p>Well, really I wanted to update the 4.1 version of entity framework, so in tools-->library package manager-->package manager I use this command:</p>
  
  <p>Install-Package EntityFramework</p>
  
  <p>Then the update started. I saw a message saying that the version 5 is installed. I my project folder I can see two foloders, one with the net4 lib and other with the net5 library.</p>
  
  <p>However, in my references in the project, the 4.1 was replaced with the 4.4, not with the 5.0 version, so I would like to know if I can use the 5.0 version or only the 4.4 version. If I only can use the 4.4 version, why is installed the 5.0 version? I know that the 5.0 version is installed because if I try to install again entity framework through the package manager, I get the following message:</p>
  
  <p>"'EntityFramework 5.0.0' already installed."</p>
  
  <p>Thanks.</p>
