Offline Installer NET Framework 2.0 , 3.0 , 3.5 , 4.0

As many of the new Microsoft Windows applications are developed using .NET Framework, it is becoming mandatory to install .NET Framework on our personal computers. Microsoft provides .NET Framework installer as a free download available to everyone. But it is an online installer. That means, initially we have to download a small piece of installer and upon starting the installation process the installer automatically connects to Microsoft servers and downloads the required components and completes the installation.

The online installers works great as long as we have internet connectivity always. But many of us required offline installer to install the software on computers not connected to internet, to save the bandwidth while installing on many computers, etc.
I gathered a set of links on Microsoft servers from where we can download the offline installers of .NET Framework 4.0, 3.5, .NET Framework 3.5 Service Pack 1, .NET Framework 3.0 and .NET Framework 2.0.
