This article will explain in detail about ASP.NET MVC 3 new features and NuPack features, the quality of the article content is high, so Xiaobian share for everyone to make a reference, I hope you have a certain understanding of related knowledge after reading this article.

NuPack ; Open Source Package Manager for. NET

NuPack is an open source package manager that makes it easier to find, install, and use. NET libraries in your projects. It works well with all. NET project types (including, without limitation, ASP.NET Web Forms and ASP.NET MVC).

NuPack enables developers maintaining open source projects (e.g., Moq, NHibernate, Ninject, StructureMap, NUnit, Windsor, RhinoMocks, Elmah, etc.) to package their libraries and register them using an online, searchable gallery/catalog. Client NuPack tools-which is highly integrated with Visual Studio-makes it easy for any. NET developer to use these libraries in their projects and install them.

NuPack handles dependency management between libraries (e.g. library1 depends on library2). It also makes it easy to modify (and remove) libraries in subsequent projects. It supports updating web.config files if a package requires configuration settings. Similarly, it allows packages to add PowerShell scripts to a project (e.g. scaffold commands). Most importantly, NuPack is transparent-and nothing is installed on the system layer. Instead, it aims to make it easier for you to use your projects to manage your libraries.

NuPack itself is an open source project. The Outercurve Foundation (formerly CodePlex Foundation) today announced the inclusion of NuPack projects in the ASP.NET Open Source Gallery.

Our goal is to make NuPack as simple as possible to integrate open source libraries into. NET projects. It supports all versions of Visual Studio. Today, you can use the development version of it to get started.

A Simple NuPack Scene-Using ELMAH

As a simple example of what NuPack can do-let's say we're working on a brand new ASP.NET application development and want to use the popular "ELMAH" library to log and report bugs on our website. To install ELMAH, you need to download it manually, extract it, add references to your project, make sure you have source control bindings to the correct installation libraries, and update your application's web.config file to include ELMAH HttpModule records. All doable--but a bit tedious.

When NuPack is installed, you can simply open the new Package Manager Console and type "Add-Package elmah" into it.

Typing "Add-Package elmah" causes NuPack to check the online location of the Elmah library, download it, add its reference to your project, and automatically add the appropriate Elmah registry entry in your application's web.config file:

We have now set up, installed Elmah and enabled error reporting logging for our project. No extra manual steps are required to make it work.

. NET and Open Source

We think NuPack will be an essential component of a. NET stack going forward. This will encourage more developers to use open source libraries. Having a standard package manager integrated into Visual Studio will also hopefully encourage more open source. NET project creation.

ASP.NET MVC 3 Beta

This release is a major update to ASP.NET MVC 3 Preview and contains a number of feature improvements.

In addition to ASP.NET MVC 3 features (introduced with the first preview), today's beta includes

Razor Enhancement: ASP.NET MVC 3 supports this new Razor View Engine option. In addition to the features in ASP.NET MVC 3 Preview, today's Beta version adds a number of additional features: Cleaner MVC integration-including the use of a new @model syntax to clean specified types being passed to views. A new @helper syntax to declare reusable HTML helpers. A new @* *@ comment syntax. C#and VB styles using Razor are supported.

New View Helpers: The new view helper method is now supported. It includes a new Chart() helper method to dynamically create charts (the same feature as control in ASP.NET 4-now using the view helper method). Also, a new WebGrid() helper method can be used to create data-grid style user interfaces (including pagination and sorting).

JavaScript and HTML compatibility 5: Now, in ASP.NET MVC, AJAX and Validation helpers use both unobtrusive JavaScript default methods. Unobtrusive JavaScript avoids injecting inline JavaScript into HTML and uses the new HTML 5 data convention to separate behavior (which is also convenient in older browsers). This will make your HTML smaller and cleaner, as well as making it easier to swap and customize JS libraries. Validation helpers in ASP.NET MVC 3 now also support jQueryValidate, the default plugin.

Dependency Injection Pattern: The original ASP.NET MVC 3 Preview has better support for Dependency Injection (DI) in Controllers, Views and Action Filters. Today's Beta version extends this functionality to support Model Binders, Model Validation Providers, Model Metadata Providers, and Value Providers with better dependency injection patterns. It also supports a new IDependencyResolver interface that makes it easier to integrate dependency injection frameworks.

NuPack Integration: ASP.NET MVC 3 automatically installs NuPack. It will leverage NuPack to discover and add a large number of MVC development and libraries to your project.

Other: The original ASP.NET MVC 3 Preview adds a lot of extra helpers and classes for better everyday coding. This beta includes a number of additional improvements: more granular XSS HTML input validation, HTML helper improvements to support HTML 5, Crypto helpers and hashed passwords, simpler Email APIs, improved "New Project" dialogs, and more.

Alternatively, you can download and install ASP.NET MVC 3 Beta (using a separate installation file) here (Note: For today's beta version, you need to install AspNetWebPages.msi first, followed by AspNetMVC3Setup.exe file).

WebMatrix Beta 2

This version is an improved version of WebMatrix Beta 1 and includes a number of feature improvements.

In addition to WebMatrix features introduced with the first beta, today's Beta 2 release also includes:

Web Page enhancements: WebMatrix supports the creation of stand-alone ASP.NET Web pages by using a new Razor syntax. It contains the same syntax improvements (@helper, @* comment *@, etc). It now also supports creating pages using VB and C#.

Improved templates: WebMatrix contains template items for common scenarios. These template projects now use HTML 5 and CSS 3 (and also work with downlevel browsers). A new Wishlist project template was added in Beta 2.

NuPack Integration: WebMatrix provides NuPack integration and supports a web-based management to install libraries into projects you are working on.

Toolkit Support: We are releasing a Toolkit that provides convenient helpers that can be used in ASP.NET applications. It contains helpers for Analytics, Facebook, GamerCard, Gravatar, LinkShare, Captcha, Twitter and Video scenarios.

Today's release further evolves and elevates Microsoft Web Stack. All of the above features work with. NET 4 and VS 2010 integration without modifying any existing files (they are attached and installed safely on your machine).

About ASP.NET MVC 3 new features and NuPack function is how to share here, I hope the above content can be of some help to everyone, you can learn more knowledge. If you think the article is good, you can share it so that more people can see it.
