| 9 | +/// This allows tools to understand which members are being accessed during the execution |
| 10 | +/// of a program. |
| 11 | +/// |
| 12 | +/// This attribute is valid on members whose type is <see cref="Type"/> or <see cref="string"/>. |
| 13 | +/// |
| 14 | +/// When this attribute is applied to a location of type <see cref="string"/>, the assumption is |
| 15 | +/// that the string represents a fully qualified type name. |
| 16 | +/// |
| 17 | +/// When this attribute is applied to a class, interface, or struct, the members specified |
| 18 | +/// can be accessed dynamically on <see cref="Type"/> instances returned from calling |
| 19 | +/// <see cref="object.GetType"/> on instances of that class, interface, or struct. |
| 20 | +/// |
| 21 | +/// If the attribute is applied to a method it's treated as a special case and it implies |
| 22 | +/// the attribute should be applied to the "this" parameter of the method. As such the attribute |
| 23 | +/// should only be used on instance methods of types assignable to System.Type (or string, but no methods |
| 24 | +/// will use it there). |
