Update 4/21/2014: please see for Update 2 RC web features.

Today, the Visual Studio team announced the release of CTP2 of Visual Studio 2013 Update 2 .  Our team added a few useful features and did some bug fixing in this update to improve the web development experience.  We will have future blogs to talk about some of the features in detail.  The release note contains more details.

New SASS project item and editor

We added LESS in VS2013 RTM, and we now have a SASS project item and editor.  SASS editor features are comparable to LESS editor, include colorization, variable and Mixins IntelliSense, comment/uncomment, quick info, formatting, syntax validation, outlining, goto definition, color picker, tools option setting etc.



New JSON project item and editor

We have added a JSON project item and editor to Visual Studio.  Current JSON editor features include colorization, syntax validation, brace completion, outlining, tools option setting and more.


Create remote Azure resources option when creating a new Web project

We added a Windows Azure “Create remote resources” checkbox on the new web application dialog.  By choosing it, you will be able to integrate the experience of creating a new web application, setting up the Windows Azure publishing site for testing, and creating publishing profile in a few simple steps.



We also supports remote debugging for WAWS and remote view of Azure website content files in the server explorer.

ASP.NET Scaffolding

If your model is using Enums, then the MVC Scaffolder will generate dropdown for Enum. This uses the Enum helpers in MVC.

Updated the EditorFor templates in MVC Scaffolding so they use the Bootstrap classes.

MVC and Web API Scaffolders will add 5.1 packages for MVC and Web API

One ASP.NET Template changes

We updated ASP.NET templates to support Account Confirmation and Password Reset.

We updated ASP.NET Web API template to support authentication using On Premises Organizational Accounts.

ASP.NET SPA template now shows a template where the authentication is based on MVC and server side views. The template has a WebAPI controller which can only be accessed by authenticated users.

LESS editor improvements

We added features including nested media queries, named parameter support, support for selector interpolation, support for semicolons as parameter separators, goto definition for @import, goto definition of variables and mixins.

Knockout IntelliSense upgrade

We added a non-standard KnockOut syntax for VS intelliSense, “ko-vs-editor viewModel:” syntax.  It can be used to bind to multiple view models on a page using comments in the form:

Code Snippet
  1. <!-- ko-vs-editor viewModel: <any javascript expression that evaluates to an object> -->
  3. <!-- /ko-vs-editor >


We also added support for nested ViewModel IntelliSense, so you may drill into deeply nested objects on the ViewModel.

<div data-bind=”text:” />

The IntelilSense displayed is the full IntelliSense of the JavaScript Object.


New URL Picker in HTML, Razor, CSS, LESS and SASS pages

VS 2013 shipped with no URL picker outside of WebForm pages.  The new URL picker for HTML, Razor, CSS, LESS and SASS editors is a dialog-free, fluent typing picker that understands ‘..’ and filters file lists appropriately for img’s and links.




Browser Link New Features

BrowserLink now supports HTTPS connections and will list that in Dashboard with other connections as long as the certificate is trusted by browser.

ASP.NET Web Forms

The Web Forms templates now show how to do Account Confirmation and Password Reset for ASP.NET Identity.

Entity Framework Data Source and Dynamic Data Provider for Entity Framework 6. For more details please see

ASP.NET MVC 5.1.1, ASP.NET Web API 2.1.1 and ASP.NET Web Pages 3.1.1 are included

We announced ASP.NET MVC 5.1, ASP.NET Web API 2.1 and ASP.NET Web Pages 3.1 in January.  We integrated that release with some minor bug fixes into VS 2013 Update 2 CTP2.

ASP.NET Identity

We integrated Microsoft.AspNet.Identity 2.0-alpha1 into the new project templates.  You can upgrade it to Microsoft.AspNet.Identity 2.0-beta1 to use two factor authentication and more features.

Entity Framework

We integrated Entity Framework 6.1.0-alpha1 into the new project template.  You can upgrade it to Entity Framework 6.1.0-beta1 to use the newest beta1 features.

Microsoft OWIN Components

We integrated stable version Microsoft OWIN Components (2.0.2) into the new project templates.  You can upgrade it to 2.1.0.  Please look at the release notes for the latest stable version (2.1.0) for more detailed information, which includes support for Google OAuth2 authentication and static file server.


NuGet 2.8 RTM is included in this release.  You can always get the latest NuGet extension for Visual Studio through the menu “Tools->Extensions and Updates…”.


We included 2.0.2 NuGet package for SignalR .  Please look at the release notes for more detailed information

Known Problems

Web Essential 2013 is not yet compatible with the Update 2 CTP2. If you install Update 2 CTP2, after opening Visual Studio, you’ll get an error message “EditorExtensionsPackage” couldn’t be loaded.   Please visit this web essential blog post on how to get the compatible build for VS2013 Update 2 CTP2.

When creating an App for SharePoint with an ASP.NET MVC web application, users will receive the following message:

o Error: this template attempted to load component assembly 'Microsoft.VisualStudio.Web.Project, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. For more information on this problem and how to enable this template, please see documentation on Customizing Project Templates

o The workaround to create a new provider-hosted or autohosted app for SharePoint using an MVC web application is to follow the steps:

  • Create a MVC web application project first.
  • After the web project is created, right-click the project node to launch the context menu.
  • In the context menu, select “Convert”, then choose “Convert to App for SharePoint Project…”.


We hope you can evaluate these new features and let us know about any bugs and suggestions.  For VS features, please use Connect to submit bugs, ASP.NET UserVoice to submit and vote for suggestions, and the ASP.NET Forums for Q&A.  For MVC/WebAPI/WebPages issues, please submit any issues you encounter and feature suggestions for future releases on our CodePlex site. Thank you!

  • After installing Update 2 it seems my web projects are completely broken...

    first of all, whenever I build they won't launch in a browser anymore. Secondly, they seem to produce allot of "500 Internal Server Error" responses...

    The projects still runs fine without the update...

    Any changes in particular I should be aware of that could cause this?

  • @Jens, are you installing Update2 RC or CTP2? Please leave comment in the Update 2 RC blog.  Or you can file a bug in connect to get official support.  Build does not suppose to launch browsers.  Ctrl-f5/F5 should launch browser.  If ctrl-f5/f5 doesn't launch browser, could you check if you changed the browser link toolbar browser?  (e.g., by default, it should be Internet Explorer).  I'm not aware of any 500 internal server error response, you should try to debug your app to see if it hits any exception.  Thanks.

  • @Xinyang Qiu

    Would that be here:

    or Here:


    Ofc. I meant hitting F5/Ctrl+F5... I didn't change anything in the toolbar.

    I already tried debugging the 500 internal server error, I don't hit any parts of my code.

  • @Jens, is the blog for web features in VS2013 update2 RC.  Please make sure you install it and try it again.  What's the target browser showing in the toolbar, is it Internet Explorer or some other browser?  You can email me directly and discuss this after you install the udpate 2 RC build and problem still persist.  xinqiu at Microsoft dot com.  Thanks.

  • @Xinyang Qiu

    Cheers, ill do that in the future, but ill post this one here as I tried installing the RC and it works now.

    Either it has been the CTP or something simply went wrong in the installation, I say the last part because If I look in my "downloads" I only seem to have downloaded copies of the RC package and there is no trace of a CTP.

    But since it works now, I don't wan't to make noise in the newer post... If any things show up ill get back to you.


  • this means that we can develop on SASS without install ruby ??

  • @Mati, please see thread for better discussion about SASS and ruby. Thanks!

  • I am new to visual studio web programming.I just made a website in visual studio 2013 ultimate but it is showing something like jquery.Please help me as fast as possible...

  • @Akshat, jquery is part of the standard VS website template.  Please check to get started with ASP.NET website.

  • SASS support is NOT complete and I don't know where the screenshot came from but here's one from reality. I just updated to WE update 3. Maybe something wrong with my eyes but I don't see the 'SASS/SCSS' option in the list, do you? Aside from not being able to create a SCSS file from the template, the preprocessor is incomplete. It does not consider all files like a real preprocessor such as Scout does. So, if you want to take advantage of all SASS features and not just the ones that are also in LESS, you still have to use a third party preprocessor. Another MS FAIL.
