I started integrating Composite C1 with an existing ASP.Net Website Project.
Putting some usercontrols which use SessionState into a MasterPage resulted in an error, saying that SessionState was not enabled.
I tried to set
<pages controlRenderingCompatibilityVersion="3.5" clientIDMode="AutoID" enableSessionState="true">
in the web.config then and add
<sessionState mode="InProc" cookieless="AutoDetect" timeout="30" />
but no success still.
Why does Session State not work and how can I enable it for my Composite C1 Project?
