MVC 4 Scripts does not exist

Question

I have just created an ASP NET MVC 4 project and used Visual Studio 2012 RC to create a Controller and Razor Views for Index and Create Actions   When I came to run the application  and browsed to the Create view  the following error was shown      Compiler Error Message  CS0103  The name  Scripts  does not exist in   the current context   The problem is the following code which was added automatically to the bottom of the View    section Scripts        Scripts Render    bundles jqueryval       Why does Scripts not exist   I looked at the base Web Page class in Assembly System Web Mvc dll  v4 0 0 0  I can see the following helper properties available    Ajax Html Url   But nothing named Scripts   Any ideas   EDIT   My Web config file looks like this  untouched from the one that Visual Studio created       lt system web webPages razor gt       lt host factoryType  System Web Mvc MvcWebRazorHostFactory  System Web Mvc  Version 4 0 0 0  Culture neutral  PublicKeyToken 31BF3856AD364E35    gt       lt pages pageBaseType  System Web Mvc WebViewPage  gt         lt namespaces gt           lt add namespace  System Web Mvc    gt           lt add namespace  System Web Mvc Ajax    gt           lt add namespace  System Web Mvc Html    gt           lt add namespace  System Web Routing    gt         lt  namespaces gt       lt  pages gt     lt  system web webPages razor gt    EDIT  2   People are blogging about using the  Scripts helper    SCOTT HANSELMAN Blog Codebetter com   Yet having just installed Visual Studio 2012 RC onto a fresh Windows 8 install I am still unable to use  Scripts even though Visual Studio adds it to the generated View   Solutions are presented below   I am not sure how to close this  because in the end an update seemed to resolve the issue  I double checked I had performed a clean install  using a new project  But the same failing project I had made works fine now after various updates and no manual obvious intervention  Thanks for all of the thoughts but there was definitely an issue at the time

I had this issue after I added an Area to a project that didn t have any  To get rid of it just copied the web config withing root Views folder to the Views folder of the area and it started working

One more for the pot - spent ages trying to work out the same problem - even though it was defined in the web config for root and the root of Views   Turns out I d mistakenly added it to the  lt system web gt  lt pages gt  lt namespaces gt   and not  lt system web   webPages razor   gt  lt pages gt  lt namespaces gt  element     Really easy to miss that

I solve this problem in MvcMusicStore by add this part of code in  Layout cshtml   if  IsSectionDefined  scripts               RenderSection  scripts   required  false      and remove this code from Edit cshtml    section Scripts        Scripts Render    bundles jqueryval       Run the program inshallah will work with you

I had the same problem and I used WinMerge to help me track this down  But as I researched it more  I found that Rick has the perfect blog post for it   Summary    Add  lt add namespace  System Web Optimization   gt  to both web config files Run Install-Package -IncludePrerelease Microsoft AspNet Web Optimization Update Bundling code Update Layout file The last step is to update 10 other libraries  I didn t and it worked fine  So looks like you can procrastinate this one  unless I already updated 1 or more of them

I ran into this problem  however while running the command   Install-Package -IncludePrerelease Microsoft AspNet Web Optimization    I received the cryptic message  gotta love a great pun before the first cup of coffee       Install-Package   The specified cryptographic algorithm is not   supported on this platform    I am running this on Windows XP SP3  not by choice  and what I found was that I had to follow the instructions posted by the user artsnob on the ASP NET Forum   Please uninstall the Nuget and try re-installing it  If you are unable to do this  login as an Administrator  Go to Tools   Extension Manager    Select  Nuget Package Manager     UnInstall Install it again  by searching  Nuget     Install  If it did not work  please try installing  1 7 x version as I mentioned in the previous post  It doesn t mean  you have to use the previous version  if it works fine  we can report this bug  and get the patches for the latest version     Once I ran this I could then run the command line to update the Web Optimization   Hope this saves someone some digging

Import System Web Optimization on top of your razor view as follows    using System Web Optimization

User · Answer

Styles and  Scripts are 2 new helpers provided by System Web Optimization library  As the name suggests  they bundle and minify CSS and JavaScript files or resources respectively   Try including the namespace System Web Optimization either by  using directive or through web config  http   ofps oreilly com titles 9781449320317 ch ClientOptimization html BundlingAndMinification  UPDATE  Microsoft has moved the bundling minification to a separate package called Microsoft AspNet Web Optimization  You can download the assembly from nuget   This post will be useful to you

Just write   section Scripts       lt script src   System Web Optimization BundleTable Bundles ResolveBundleUrl    bundles jqueryval    gt  lt  script gt

User · Answer

The key here is to add     lt add namespace  System Web Optimization    gt     to BOTH web config files  My scenario was that I had System Web Optimization reference in both project and the main root web config but  Scripts still didn t work properly  You need to add the namespace reference to the Views web config file to make it work   UPDATE   Since the release of MVC 4 System Web Optimization is now obsolete  If you re starting with a blank solution you will need to install the following nuget package   Install-Package Microsoft AspNet Web Optimization   You will still need to reference System Web Optimization in your web config files  For more information see this topic   How to add reference to System Web Optimization for MVC-3-converted-to-4 app  As many pointed out  restart of VS could be required after the above steps to make this work

Apparently you have created an  Empty  project type without  Scripts  folder  My advice -create a  Basic  project type with full  Scripts  folder   With respect to all developers

User · Answer

If you added   to your web config and it still shows message  then you need to close your project and reopen it  now it will exist and  Styles Render     and  Scripts Render   will work fine

When i started using MVC4 recently i faced the above issue while creating a project with the empty templates  Steps to fix the issue    Goto TOOLS --  Library Package Manager --  Packager Manager Console Paste the below command and press enter Install-Package Microsoft AspNet Web Optimization Note  wait for successful installation   Goto Web Config file in root level and add below namespace in pages namespace section  add  lt namespace  System Web Optimization    gt  Goto Web Config in Views folder and follow the step 2  Build the solution and run    The Package mentioned in step 1 will add few system libraries into the solution references like System Web Optimization is not a default reference for empty templates in MVC4   I hope this helps  Thank you

That has an obvious solution  I had the same problem later  Not related to Assembly References or      It ll occur In hierarchy calling of MVC Partial views  when you have complicated page structures  So calling rendering each part separately on each page  maybe a master page or partial  will cause to not see required parts of page like the bellow code     RenderSection  Scripts   required  false    That simply forces page to find and render related section and in case of failure shows you an error message like you   So I suggest you to trace your pages  like program trace  from master to all of its partials to Detect Dependencies  Maybe it be a terrible work  but no other choices available here   Not that according to my experience  some conditional situations in programming causes not to show you the right error causes the problem

I had the same issue   The System Web Optimization version I was using was outdated for MVC4 RC   I updated my packages using the package manager in VS 2010   In this MSDN blog  Mr  Andy talks about how to update your MVC 4 Beta project to MVC 4 RC   Updating my packages got the Scripts  particularly the web optimization one  to resolve for me   To install the latest System Web Optimization package  use Package Manager Console  Tools -  Library Package Manager -  Package Manager Console  and run the below command   Install-Package -IncludePrerelease Microsoft AspNet Web Optimization   Use the System Web Optimization file included in the package in your references   To update other packages  Tools menu -  Library Package Manager -  Manage NuGet Packages for Solution
