Hope someone can shed some light on this, pretty sure it's not me, although i can never entirely rule that out /emoticons/smile.gif Uploaded a Dynamic Data Web App based on Entity Framework about a month ago, all worked fine. Carried out a few changes on my development machine yesterday and today, no problems, all working as it should, but when i uploaded the updated version to this hosting, i'm now getting the following error. The stack trace points to the model.RegsiterContext method call in the Global.asax - i thought initially that it was being caused by my usage of a custom data model provider (Microsoft.Web.DynamicData.EFDataModelProvider) which is a workaround to a few bugs in the Entity Framework (even though the relevant DLL was in the BIN folder anyway), so i took that out and tried again just in case, and am still receiving the same error. I'm presuming the relevant provider from the web.config is providerName='System.Data.EntityClient' Cheers
