This attribute class provides declarative syntax support for EnvironmentPermission. The All, Read, and Write properties take semicolon-separated lists of environment variable names to which the EnvironmentPermissionAttribute represents access. Read specifies the environment variables to which read access is granted, and Write specifies the environment variables to which write access is granted. The All property contains the variables to which both read and write access is granted. Setting Unrestricted to true represents full access to all environment variables.
