What does 'Fully Trusted' Mean and Imply for .NET Frameworks?
Fully trusted, wholeheartedly accepted, no boundaries or restrictions, allowed... these descriptors (interpreted in this context), all pertain to a certain level of permission, trust, allowing rights, privileges. It is the broadest, open category or set, referring to an assembly that is exempt from CAS permission checks.
Partially trusted assemblies, applications, arenas, users etc. must all go through the gate-keeping, safe-guarding checks, check-points of CAS everytime it tries to access a protected record, object, file, system, network, message etc. Exempt assemblies, domains, applications, would not have to adhere or go through the CAS ‘verification’, authorization, authentication, type processes, deal with the set/default, inherited or customized permissions (sets, levels or policies, checks), in order to proceed, or be allowed, not denied. Fully trusted, sources, domains and applications, files, objects, or even like unmanaged code for example, have the ability and allowance to access any and all system resources that the user has ‘permission’ for/to.
EXAM TIP: CAS is only for partially trusted assemblies and applications. Runtime disregards, pays no heed to CAS declarations for fully trusted assemblies.
