OnSeralized do work with SoapFormatter

Question

Hi

.Net Application Development foundation by Northup, I cannot find a errata related to this, but when I try use SoapFormatter with OnSerialzed attribute it works fine, while the book is saying on first paragraph on page 308, that this attribute works only with BinaryFormatter. How do u explain?

I suspect that the problem is related to framework upgrade from .Net2 to 3.5 but I found that it also works with .Net2.

I don't whether MCTS exam is based on the latest framework behavior or it stick with .Net 2?

Thanks
