Ongoing DotNetNuke 5.0 Merge Grief...

As part of trying to move this RunSaturday code from 4.9 on my dev box to DNN 5.0 on a GoGrid virtual server.... I've stumbled across all sorts of DNN and ASP issues - on the negative side, this is quite dull... on the plus side, it's all still learning....

So I've carried on and I stumbled across an error "Unknown server tag 'asp:ListView'"

Looking through the ASP.NET forums this seemed to indicate that I hadn't quite correctly ported the DNN web config file correctly to 3.5 from 2.0.... but it looked OK... eventually WinDiff (WinMerge) showed me what was wrong... I was missing this line from the <controls> section of web.config:
