Man, I've been fighting this problem for hours before I found the reason. Having added everything correctly to the zip file and deploying everything to the correct location, why is the webserver not picking up my extensions and presenting them in the top menu?
Look at the below - nothings shows up but the standard apps. Why?
Come on - how crazy is this? I for one am not very impressed! How did I discover this? Well - crack open the InRiver.Web.dll (thank you DotPeek!)
