Asp.net MVC5 WebRole after deployed to Azure Cloud, breaks on @Scripts.Render

Solution

After days of tests I discovered that the problem is the WEBGREASE package. Updating it will cause the problem even on a fresh new project. For now uninstalling it and reinstalling the previous version solved the problem.

Problem

I have a cloud service with an Asp.Net MVC 5 Web Role and Azure SDK 2.3 targeting 4.5.1 framework; The website works perfectly in Local. But when I deploy it to Azure Cloud service, I have the classic null reference error: Object reference not set to an instance of an object. Exception Details: System.NullReferenceException: Object reference not set to an instance of an object. Source Error: ``` Line 9: @Scripts.Render("~/bundles/jquery") ``` My BundleConfig.cs is simple: ``` public static void RegisterBundles(BundleCollection bundles) { bundles.Add(new ScriptBundle("~/bundles/jquery").Include( "~/Scripts/jquery-{version}.js", "~/Scripts/knockout-{version}.js", "~/Scripts/jquery.signalR-{version}.js", "~/Scripts/modernizr-{version}.js" )); ``` Using Intellitrace Logs on the WebRole I can see this error: invalid file name for file monitoring 'E:\sitesroot\0\Scripts Entering remotely in the instance I see that the folder Scripts is exactly in that path. Removing the @Script.Render the page load normally. The @Style.Render on the same page works. I tried to deploy in Debug mode, and Release mode, both in Staging. Also tried to change in Web.config the ``` compilation debug="true" and false ``` with no success. Any ideas why could happen this? Thanks
