'<membername>' is obsolete: '<errormessage>'
A statement attempts to access a class or structure member which has been marked with the ObsoleteAttribute attribute and the directive to treat it as an error.
You can mark any programming element as being no longer in use by applying ObsoleteAttribute to it. If you do this, you can set the attribute's IsError property to either True or False. If you set it to True, the compiler treats an attempt to use the element as an error. If you set it to False, or let it default to False, the compiler issues a warning if there is an attempt to use the element.
