'member' is obsolete: 'text'
A class member was marked with the obsolete attribute, such that an error will be issued when the class member is referenced.
The following sample generates CS0619:
public class C { [obsolete("Use newMethod instead", true)] // generates an error on use public static void m() { } // this is the method you should be using public static void newMethod() { } } class MyClass { public static void Main() { C.m(); // CS0619 } }
