Configuring Code Groups Using the .NET Framework Configuration Tool (Mscorcfg.msc)
A code group checks whether an assembly matches an administrator-defined criteria called a membership condition. If the assembly matches, the code group grants the assembly a set of permissions that has been associated with that code group.
You can use the .NET Framework Configuration tool (Mscorcfg.msc) to configure code groups.
Mscorcfg.msc has been removed from the .NET Framework version 4 and later versions. This documentation applies only to earlier versions of the .NET Framework. For more information about security changes in the .NET Framework 4, see Security Changes in the .NET Framework 4.
