* FxCop is intended for class library developers. However, anyone creating applications that should comply with the .NET Framework best practices will benefit. FxCop is also useful as an educational tool for people who are new to the .NET Framework or who are unfamiliar with the .NET Framework Design Guidelines. * FxCop is designed to be fully integrated into the software development cycle and is distributed as both a fully featured application that has a graphical user interface (FxCop.exe) for interactive work, and a command-line tool (FxCopCmd.exe) suited for use as part of automated build processes or integrated with Microsoft Visual Studio® .NET as an external tool.
