In order to run and host ASP.NET Web pages, you will need to have installed the .NET Framework onto a machine already running on Windows 2007/ Windows 8/ Windows 10.
Microsoft recommends that you develop under Windows 2000, although it is possible to use Windows XP. Unfortunately, Windows 98 and Windows NT 4 are not supported at the time of this writing, although you can use Visual Studio.
There are two versions of the software development kit (SDK): The standard .NET Framework download and the premium .NET Framework version.
The main difference between the two is that the premium edition provides support for multiple processors,
Web farms, and sandbox security.
1. You can get the .NET Framework Software Development Kit from Microsoft Official site by request or via their developer’s network subscription service.
2. The SDK is available for download from ASP.NET as well as from Microsoft’s corporate site,
Installation is really simple and it is advisable that you install all components including the ADO update and the samples, if you are installing on your own development machine.
3. You can install sample applications, a set of databases in a desktop version
of Microsoft SQL Server, called the Microsoft Data Engine (or Microsoft SQL Server Desktop Edition according to the installation program), as part of the full installation by selecting the option once all SDK files are Setup.
