This can lead to security issues for components that expect the runtime to honor CAS-related attributes or programmatic API calls. This led to "fail open" scenarios, where some CAS-related APIs exist and are callable but perform no action at run time. However, the APIs were brought forward so that apps could cross-compile against. NET Framework 2.x - 4.x, but is deprecated and not receiving servicing or security fixes.ĭue to CAS's deprecation, the supporting infrastructure was not brought forward to. The infrastructure to enable CAS exists only in. Reason for changeĬode access security (CAS) is an unsupported legacy technology. NET Core 2.x - 3.x will continue to throw a PlatformNotSupportedException at run time in. Methods that throw PlatformNotSupportedException in.

NET 5 and later versions, most CAS-related APIs are obsolete and produce compile-time warning SYSLIB0003. New SocketPermission(PermissionState.Unrestricted).Deny() The line below throws PlatformNotSupportedException at run time. New SocketPermission(PermissionState.Unrestricted).Assert() The line below has no effect at run time. See the Recommended action section below.) public void DoAssert() ( PrincipalPermission is an exception to this rule. NET Core runtime ignores the following attribute.Īdditionally, programmatic calls to expansive APIs ( Assert) always succeed, while programmatic calls to restrictive APIs ( Deny, PermitOnly) always throw an exception at run time. The runtime ignores attributes on method entry, and most programmatic APIs have no effect. NET Core 2.x - 3.x, the runtime does not honor CAS attributes or CAS APIs. to terminate successfully when this permission is demanded. NET Framework, the attribute causes CAS stack walks

NET Framework 2.x - 4.x, CAS attributes and APIs can influence the course of code execution, including ensuring that CAS-demand stack walks succeed or fail. This includes CAS attributes, such as SecurityPermissionAttribute, CAS permission objects, such as SocketPermission, EvidenceBase-derived types, and other supporting APIs. Most code access security (CAS)-related types in. Most code access security APIs are obsolete
