title: Check .NET 4 Full Framework is installed
body: <p>If the .NET 4 Framework is not installed, the application bring a message, but if only the client framework is installed and the application need the Full Framework, nothing happened and the application starts.</p>
  
  <p>Is there a way to check if .NET 4 Full Framework is installed on the target system and not only the Client Framework?</p>
  
  <p>I search a solution to check it with the "app.manifest" file or in C# on program start.</p>
