ASP.NET MVC 5
What's New in ASP.NET MVC 5
The Web MVC project templates integrate seamlessly with the One ASP.NET experience. You can customize your MVC project and configure authentication using the One ASP.NET project creation wizard. An introductory tutorial to ASP.NET MVC 5 can be found at Getting Started with ASP.NET MVC 5.
For information on upgrading MVC 4 projects to MVC 5, see How to Upgrade an ASP.NET MVC 4 and Web API Project to ASP.NET MVC 5 and Web API 2.
The MVC project templates have been updated to use ASP.NET Identity for authentication and identity management. A tutorial featuring Facebook and Google authentication and the new membership API can be found at Create an ASP.NET MVC 5 App with Facebook and Google OAuth2 and OpenID Sign-on and Deploy a Secure ASP.NET MVC app with Membership, OAuth, and SQL Database to a Windows Azure Web Site.
The MVC project template has been updated to use Bootstrap to provide a sleek and responsive look and feel that you can easily customize. For more information, see Bootstrap in the Visual Studio web project templates.
Authentication filters are a new kind of filter in ASP.NET MVC that run prior to authorization filters in the ASP.NET MVC pipeline and allow you to specify authentication logic per-action, per-controller, or globally for all controllers. Authentication filters process credentials in the request and provide a corresponding principal. Authentication filters can also add authentication challenges in response to unauthorized requests. See ASP.NET MVC 5 Authentication Filters, Authentication Filters in ASP.NET MVC 5.
You can now override which filters apply to a given action method or controller by specifying an override filter. Override filters specify a set of filter types that should not be run for a given scope (action or controller). This allows you to configure filters that apply globally but then exclude certain global filters from applying to specific actions or controllers. See New Filter Overrides feature in ASP.NET MVC 5 and ASP.NET Web API 2, How to use the ASP.NET MVC 5 Filter Overrides Feature, and Filter Overrides in ASP.NET MVC 5
ASP.NET MVC now supports attribute routing, thanks to a contribution by Tim McCall, the author of http://attributerouting.net. With attribute routing you can specify your routes by annotating your actions and controllers.
New Web Project Experience
Visual Studio enhanced the experience of creating new web projects, starting in Visual Studio 2013. In the New ASP.NET Web Project dialog you can select the project type you want, configure any combination of technologies (Web Forms, MVC, Web API), configure authentication options, add Docker support, and add a unit test project.
The dialog enables you to change the default authentication options for many of the templates. For example, when you create an ASP.NET Web Forms project you can select any of the following options:
- No Authentication
- Individual User Accounts (ASP.NET membership or social provider log in)
- Work or School Accounts (Active Directory in an internet application)
- Windows Authentication (Active Directory in an intranet application)
ASP.NET Scaffolding is a code generation framework for ASP.NET Web applications. It makes it easy to add boilerplate code to your project that interacts with a data model.
In versions of Visual Studio prior to 2013, scaffolding was limited to ASP.NET MVC projects. Starting in Visual Studio 2013, you can use scaffolding for any ASP.NET project, including Web Forms. Visual Studio does not currently support generating pages for a Web Forms project, but you can still use scaffolding with Web Forms by adding MVC dependencies to the project. Support for generating pages for Web Forms will be added in a future version.
When using scaffolding, all required dependencies are installed in the project. For example, if you start with an ASP.NET Web Forms project and then use scaffolding to add a Web API Controller, the required NuGet packages and references are added to your project automatically.
To add MVC scaffolding to a Web Forms project, add a New Scaffolded Item and select MVC 5 Dependencies in the dialog window. There are two options for scaffolding MVC; Minimal dependencies and Full dependencies. If you select Minimal dependencies, only the NuGet packages and references for ASP.NET MVC are added to your project. If you select Full dependencies, the minimal dependencies are added as well as the required content files for an MVC project.
Support for scaffolding async controllers uses the async features from Entity Framework 6.
