Vesta,

For VS 2005, you will have to use the workarounds documented on the previous post.

Oh oh, thats interesting... I had missed that other post detailing the issue.

I had that issue before (when I was explicitely encrypting viewstate, not because I was using a datakey), and had successfully figured out the issue.

However, I didn't quite understand WHY it happened (since ViewState is one of the first fields in the page). I wasn't aware that encryption of viewstate added a field near the bottom, never notice...

Now -that- explains it. Glad that its fixed in SP1.

I'm glad you commented on this; I didn't know you had posted on this before but the information could be very useful to us at work. Thanks!

This update has also effected the rendering of said tags in projects compiled for the 2.0 framework. I'm quite surprised to see the update effect NET 2.0, we now have a little issue to figure out.

Our developers use VS 2008 targeting NET 2 framework but production has not yet 'approved' nor do we have a need for NET 3.5. What was done to 2.0? How do we get this fix to production?

After some investigation it appears that the 3.5 SP1 includes NET 2.0 SP2. I can find no info on a standalone NET 2.0 SP2 install or how you might apply only the 2.0 SP2 to a non 3.5 system.

ViewState validation troubles?

If you work with web sites in a complex/multi server environment you might be familiar with this error

I'm having this exact issue on a 3.5 sp1 site when there's only 1 label on the form (in an updatepanel) The updates itself every 5 secs with the current time. The error starts occuring after approx. 2:50 minutes. I'll follow up with more info...
