Microsoft .NET Framework security updates support different command-line switches. Which switches are supported depends on the chain installer that is used to build the update package. For versions of the Microsoft .NET Framework that are included in supported releases of Windows, the standard command-line switches for Windows software update packages are supported. For other versions of the Microsoft .NET Framework, the command-line switches that are described in this article are supported.


We package software updates by using several different self-extracting file formats that automatically run a Setup program that is contained in the package. This article describes the command-line switches that you can use with Microsoft .NET Framework security updates.
