Did anyone ever find out why this occured Ive just had the exact same problem. Thanks for posting a solution but I would still like to be able to recover the missing tab. I have found that the propertypages tab is also 'greyed out' so it is unselectable.

If you have any news on this it would be appreciated.

Did anyone here manage to get this problem solved? Sounds Like a similar problem I have with the 2010 version, Step 7 P558 again!

chapter 18 ASP.NET anomaly.

What is it with this paragraph?
