Known issues for ASP.NET with .NET 3.5 SP1

Just wanted to give a heads up on two issues that we are aware of that were introduced with .NET 3.5 SP1.
Issue:  The HtmlForm action attribute is now honored when defined in declarative markup. Reason:
3.5 SP1 added a settable Action property to the HtmlForm type.  This new feature makes it much easier for developers to explicitly set the formââ?¬â?¢s action attribute for scenarios where a developer wants to use a different Url than the normal postback-generated Url.  However this change also means that if the action attribute has been set in an .aspx pageââ?¬â?¢s declarative markup, ASP.NET will use the setting from the markup when rendering a <form /> element.
Workaround:
Previous versions of ASP.NET always ignored the action attribute if it was present in the declarative markup for a <form /> element.  Developers should remove the action attribute from their declarative markup ...
