http://ayende.comAyende @ RahienCopyright (C) Ayende Rahien 2004 - 2021 (c) 202660Hi all I'm the escalation engineer that worked with Ayende and our product team to get this fix out the door. I can promise you there is no treachery going on here :-) just a bit of plain old fashioned confusion. Like most of our hotfixes you have to call support to obtain the fix (although we are working on improving that). In fact this fix will be included in a post SP1 "GDR" due for release later this year which you will be able to get without calling support. But in the meantime, you need to raise a support case (no charge), sorry. When we finalise a fix, it goes onto an internal website that support folks use to send out fixes to our customers. The publication of the KB talse a little longer as it has to go through our writing / editing / localisation team. Apologies if you are being told this fix is not available. If someone tells you it is, explain to them you've been told the KB is not quite yet published but the fix IS available. If you are really stuck, please contact me ( d o u g s t e AT microsoft.com) Thanks Doug Stewart http://ayende.com/3610/kb957541-is-my-favorite-hotfix#comment7http://ayende.com/3610/kb957541-is-my-favorite-hotfix#comment7Fri, 17 Oct 2008 08:22:09 GMTTim, Here is a second reference: [blogs.msdn.com/.../...t-net-framework-3-5-sp1.aspx](http://blogs.msdn.com/dougste/archive/2008/10/07/what-s-in-microsoft-net-framework-3-5-sp1.aspx) http://ayende.com/3610/kb957541-is-my-favorite-hotfix#comment6http://ayende.com/3610/kb957541-is-my-favorite-hotfix#comment6Wed, 08 Oct 2008 21:26:38 GMTThere's treachery afoot. Spoke to an MSDN concierge today. They advised me to phone the MSDN developer support, which I duly did. They had no record of KB957541. I got back in touch with the concierge who confirmed that indeed it doesn't exist. Has anyone managed to obtain the hotfix?? http://ayende.com/3610/kb957541-is-my-favorite-hotfix#comment5http://ayende.com/3610/kb957541-is-my-favorite-hotfix#comment5Wed, 08 Oct 2008 12:15:14 GMTi get an engineexecutionexception at asp.net development webserver when hosting WCF services that return the object they got as parameters (after modifying them slightly). as i'm using .net 3.5 sp1 i'm wondering if this may be related to the engineexecutionexception you are talking about. if so...i can't wait for this hotfix... thanks for this tipp http://ayende.com/3610/kb957541-is-my-favorite-hotfix#comment4http://ayende.com/3610/kb957541-is-my-favorite-hotfix#comment4Thu, 02 Oct 2008 05:11:18 GMTNice to know. Luckily I never had problems due to that bug (*finger crossed*), but I realize it's great that it has been taken care of. I'm looking forward to the fix. http://ayende.com/3610/kb957541-is-my-favorite-hotfix#comment3http://ayende.com/3610/kb957541-is-my-favorite-hotfix#comment3Fri, 26 Sep 2008 06:36:45 GMTIt is not public, you have to call and ask for it.
