Cannot use 'partitionResolver' unless the mode is 'StateServer' or 'SQLServer'

Have you ever got this error while trying to run an ASP.NET 2.0  web application in same port containing SharePoint 2007 Portal?

If yes here is the fix :

Add partitionResolverType="" in your ASP.NET web.config file

e.g.

sessionState mode="InProc" stateConnectionString="tcpip=127.0.0.1:42424" partitionResolverType="" sqlConnectionString="data 

source=127.0.0.1;Trusted_Connection=yes" cookieless="false" timeout="20"
