.Net known bugs list
Regarding the .Net 1.1 service pack, maybe they fixed some of the bugs reported on this post (list provided by Stefano Demiliano).
However Simon Hewitt send me this comment today about a SOAP bug:
SoapFormatter chokes on some strings
Why has this been marked "not as a bug"?
Just because XML doesn't support a character in the 0x00 - 0x1f range, doesn't mean that serialized data can't be escaped to '�e;' where necessary.
This bug makes a complete mess of remoting using SOAP.
