I'm trying to install WFFM into Sitecore XP 8.1.
Following installation, the WFFM options appear in the desktop as expected. However, if I then do a clean and rebuild in Visual Studio, I then get the following error whenever I try to access any page on the site/in sitecore:
Could not resolve type name: Sitecore.Form.Core.Utility.HttpContextPerRequestStorage, Sitecore.Forms.Core (method: Sitecore.Configuration.Factory.CreateFromTypeName(XmlNode configNode, String parameters, Boolean assert)).
I then have to roll back all changes in order to bring the site back up - when I do this, the WFFM option is still present in my desktop menus, but then disappears again when I sync with Unicorn.
Can anyone enlighten me on this? I'm very new to Sitecore (picking up a project from someone else), and there seems to be no documentation for if things go wrong like this...
