Login show .NET Framework does not enable CAS policy by defaultⓔ

Overview:

The error message "this release of the .NET Framework does not enable CAS policy by default" occurs when a .NET application attempts to use Code Access Security (CAS), a legacy security model that is disabled by default in the .NET Framework versions 4.0 and later.
