Merhaba Arkadaşlar,
Orchard Cms'nize modül yazmak istediğinizde (1.7.x), View sayfalarında IntelliSense'nin hatalı çalıştığını farkedeceksiniz.

Bu hatanın sebebi, codegen module .... şeklinde otomatik olarak oluşturulan, web.config dosyalarının, Mvc 3
sürümünü referans ediyor olması. Ancak sistemde kullanılan Mvc sürümü ise 4. Buna benzer olarak Mvc.Razor vs. dosyalarda
da sürüm uyumsuzluk sorunları mevcut.
Çözüm olarak ise iki adımlı yapmamız gereken işlem var,
