About Microsoft .NET Framework Version 1.1 (archived)

The Microsoft .NET Framework version 1.1 redistributable package included everything you needed to run applications developed using the .NET Framework 1.1.

The .NET Framework version 1.1 provided improved scalability and performance, support for mobile device development with ASP.NET mobile controls (formerly the Microsoft Mobile Internet Toolkit), support for Internet Protocol version 6, and ADO.NET classes for native communication with Open Database Connectivity (ODBC) and Oracle databases.

Status. .NET Framework 1.1 is one of the earliest versions of the .NET Framework and has been out of support for many years. It is not part of the newer .NET Framework packages and is not intended for current versions of Windows. Programs that need .NET 2.0, 3.0 or 3.5 use .NET Framework 3.5 SP1, and newer programs use .NET Framework 4.8.1.
