Having a set of the .NET Frameworks that works correctly is important for all Windows users and developers are no exception. Through the course of development, it is easy to accidentally overwrite needed files. In an effort to minimize troubleshooting, Microsoft provides the .NET Framework Repair Tool. This tool provides the ability to scan a Windows system for errors with any of the .NET Framework packages that are supposed to be installed.
The program may be executed via the command line or through a graphical wizard. Command line switches are available which allow the tool to be run unattended and to enable proper .NET packages to be located on a network share (versus requiring Internet access).
