SerializationException when using SQL Server for sessionState

[Jorge]

I get the following exception when sessionState = SQL mode

Hi Jorge,

As stated in the error message, please attribute your persistence class with [Serialize]. E.g.

[Serialize]
Class Test
{
....
}

It should resolve the problem.

Many thanks.
