| __`SYSLIB0052`__ | This API supports obsolete mechanisms for Regex extensibility. It is not supported. |
| __`SYSLIB0053`__ | AesGcm should indicate the required tag size for encryption and decryption. Use a constructor that accepts the tag size. |
| __`SYSLIB0054`__ | Thread.VolatileRead and Thread.VolatileWrite are obsolete. Use Volatile.Read or Volatile.Write respectively instead. |
| __`SYSLIB0055`__ | The underlying hardware instruction does not perform a signed saturate narrowing operation, and it always returns an unsigned result. Use the unsigned overload instead. |
