Enabling feature .Net Framework 3.5 and Framework 2.0 on Windows 2012

Enabling feature .Net Framework 3.5 and Framework 2.0 on Windows 2012
Problem: The .Net Framework 3.5 and Framework 2.0 feature is initially not installed on a new windows 2012 server.  It has an installation status of "removed"

[ ] .NET Framework 3.5 Features                         NET-Framework-Features         Available
    [ ] .NET Framework 3.5 (includes .NET 2.0 and 3.0)  NET-Framework-Core               Removed
    [ ] HTTP Activation                                 NET-HTTP-Activation            Available
    [ ] Non-HTTP Activation                             NET-Non-HTTP-Activ             Available
[X] .NET Framework 4.5 Features                         NET-Framework-45-Fea...        Installed
    [X] .NET Framework 4.5                              NET-Framework-45-Core          Installed
    [ ] ASP.NET 4.5                                     NET-Framework-45-ASPNET        Available

I am still trying to figure out WHY this is not "Available", but there appears to be 2 ways to install the NET-Framework-Core
 
Method 1:
 
Open Run with administrator privilege, and type this at the command :
dism.exe /online /enable-feature /all /featurename:NetFX3 /Source:D:\sources\sxs /LimitAccess

 Method 2: using GUI

1. You have to insert Windows Server 2012 DVD or iso to D drive.
2. Open Add Roles and Features Wizard
3. Select .NET Framework 3.5 Features and then click next,
4. Select Specify an alternate source path link in the Confirm installation selections screen.
5. Path: D:\Sources\SxS and then click OK.
6. Finally click Install button.
 
 Method 2: using PowerShell
