In my previous posted some default web.config files for running under ASP.net 4.0.In the comments @frederikvig talked about the potential of a NuGet package to make the changes.
I am guessing that most new EPiServer installations are targeted against .net 4.0. Well the ones running at my company certainly are! Allan Thræn has already documented how to set up EPiServer CMS 6 to run on .net 4.0. This involves some web.config changes and an optional modification to the .csproj file.
However I don’t want to manually make these changes each time in order to run EPiServer under .net 4.0 as I frequently have to set up new demo sites. I’ve had default web.config’s for the Alloy Tech demo site and core install on my machine for a while so wanted to share them here in the hope it saves some other people time.
