title: Multi-targeting .NET Framework 4 and Visual Studio 2012
body: <p>I have installed Visual Studio 2012 Professional on my machine. I don't have Visual Studio 2010 installed, but I want to keep developing my applications using .NET Framework 4, but I don't have this option on my Visual&nbsp;Studio&nbsp;2012. Look at the image:</p>

  <p>I don't know what can I do to fix this problem, because I click on "More Frameworks..." link and try to install the Multi-Targeting for .NET 4.0.3 (installed on my machine), but it does not work. It says that this version of framework is still installed. What can I do to fix this problem?</p>
  
  <p>Obs: I have lots of projects in C# and VB.NET with .NET 4.0, and I need to keep these projects with new projects on .NET 4.0.</p>
