.NET ViewState Decoder

Is there any viewstate decoder that really works on .net 4?

I tried Onion's and several other online decoders. There was also an add-in for firefox but that is not compatible with ff4.

I get this error no matter what.

"There was an error decoding the viewstate string. The开发者_如何学Go serialized data is invalid"

I have explicitely set ViewStateEncryptionMode="Never" EnableViewStateMAC="false" in my page. Still the same error.

Thanks
