Random Error - LanguageSelector.AutoDetect Not Found


Everything was working perfectly then I rebuilt my solution and now when I'm trying to save, I get the following error:

Method not found: 'EPiServer.Core.ILanguageSelector EPiServer.Core.LanguageSelector.AutoDetect(Boolean)'.

Any ideas? I'm so confused why a simple change all of a sudden is causing such a mess.

I've reverted the one change I made, but with no luck. Could this be a database issue all of a sudden?

I'm on EPiServer 8.3.0.

Take a look at the callstack to see where the error originates from? 

My guess is that you have some third party code (addon or similar) that is not upgraded to a CMS8 version. That error is typically something you could see if a code compiled against some 7.x.x version of EPiServer is executed in a 8.x.x. environment of EPiServer.
