Seven Web Application Toolkits are available for download at the MSDN Code Gallery. These toolkits are aim to provide web developers with resources (such as project templates, controls, code samples, and documentation) in a consistent packaged format that can be consumed and put to use in a very short time so that they can evaluate the technology and determine if it's the right solution for their problem. An introduction to the toolkits is available on Channel 9, and the kits are available for download HERE.

The current kits are:

• Web Application Toolkit for Internet Explorer 8 Extensibility [screencast]
  Today users can access rich information and services while they are browsing a site; it's not a trivial task to expose this content to the same users when they are not on that site. The goal of this Web Application Toolkit is to leverage the new features in Internet Explorer 8 (Web Slices, Accelerators and Visual Search Providers) to extend the reach of your web site and services also to those users that are not on your site. The Web Application Toolkit includes a set of ASP.NET Web Controls that you can use to take advantage of these IE new features in your own Web application.
  
• Web Application Toolkit for Bing Search
  Bing is a powerful new Decision Engine designed to help consumers accomplish tasks and make faster, more informed decisions. The Bing Application Programming Interface (API) provides developers programmatic access to Bing, offering flexible options for building or enhancing your site or applications. This Web Application Toolkit shows how to take advantage of the Bing API to add search capabilities to your Web site by leveraging the various search results that the Bing API provides, including Web content, images, news and videos, among others. Through this Web Application Toolkit you will also discover how to use ASP.NET AJAX and jQuery to provide an enhanced and more interactive end user experience when using the Bing API.
  
• Web Application Toolkit for REST Services [screencast]
  Many Web applications today are starting to expose data as REST service interfaces, so it can be accessed through APIs by other tiers of the application or even by other applications. A RESTful web service is a simple Web service implemented using HTTP and the principles of REST. REST Services focus on resources; each one is represented by a unique URI, and users interact with them via their URI using the HTTP uniform interface. This Web Application Toolkit shows how to easily add REST service interfaces for an existing Web application. The Web Application Toolkit includes a sample REST service, two sample client applications that access the REST services, one using simple ASP.NET Web Forms and a second Web application using AJAX to asynchronously invoke the REST service and finally a custom project template for Visual Studio to make it very easy to build new REST Services.
  
• Web Application Toolkit for Mobile Web Applications [screencast]
  This Web Application Toolkit is designed to demonstrate how to extend an existing ASP.NET MVC Web application to provide access from mobile devices. To enable mobile access, the Web application should have views targeting each of the mobile devices to be supported. The MVC pattern helps you create applications that separate the different aspects of the application (input logic, business logic, and UI logic), while providing a loose coupling between these elements. This Web Application Toolkit provides a component called MobileCapableViewEngine that enables the Web application to show the appropriate view depending on the device's browser that is performing the request. It also includes a sample site that provides different views for Windows Mobile, IPhone, and Blackberry devices.
  
• Web Application Toolkit for Template-Driven Email [screencast]
  This Web Application Toolkit is designed to demonstrate how to generate and send dynamic, template-based emails from a web application. There are many common scenarios where notification emails need to be sent to end users. Examples of these common scenarios may involve notifying a user of their newly created account, sending a new password in respond to a forgotten password request, or emailing an alert under specific business circumstances, such as the creation of a order. Typically the E-mails sent from a Web application scenario are formatted as HTML, include CSS stylesheets, and images and need to be generated dynamically with custom or user-specific data. This Web Application Toolkit includes samples that show how to use templates to generate these dynamic email bodies.
  
• Web Application Toolkit for making Your Web Site Social [screencast]
  Adding social capabilities to your Web site allows you to attract new users, keep them on your Web site for longer and get them to come back more often. This Web Application Toolkit shows how, using a few lines of code with the Windows Live Messenger Web Toolkit, it is possible to add social capabilities to a Web site with instant messaging from a website to various client endpoints like Windows, Windows Mobile, Xbox 360 and Mac. Behind the scenes is a powerful set of UI Controls and a JavaScript library that connect your website to the Messenger Service which is used by 330 million users around the world.
  
• Web Application Toolkit for FAQs [screencast]
  The majority of web sites have the need to display a list of frequently asked questions to their users. Although it's not difficult to create a simple set of FAQ pages, creating a great user experience that supports searching for FAQs, filtering, and paging, can become more difficult. Furthermore, this is often common functionality that has to be implemented repeatedly in multiple Web sites. This Web Application Toolkit is designed to provide a starting set of code including ASP.NET pages, data access logic, and database schemas, for integrating Frequently Asked Questions into your own ASP.NET MVC Web application.

These samples are designed to up and running in no time (seriously!), you can use these with the Microsoft Web Platform Installer.
