Running a ASP.NET 4 app in .NET 2.0 app pool
Question
I recently upgraded a .NET 2.0 app to .NET 4 and everything works great.
When I setup IIS I selected .NET 2.0 under the ASP.NET tab in IIS 6.
The app runs fine but I get these intermittent ViewState errors.
Could the IIS setup be causing the ViewState issues?

Probably because view state in .Net 4 uses a different algorithm than earlier
ASP.NET uses both encryption and hashing algorithms to help secure data such as forms authentication cookies and view state. By default, ASP.NET 4 now uses the HMACSHA256 algorithm for hash operations on cookies and view state. Earlier versions of ASP.NET used the older HMACSHA1 algorithm.
You need to register .Net Framework 4.0 in IIS, then run your site under Application pool for .Net 4.0
