Several new Web App Toolkits were released recently:

• “Freemium” - A popular way to attract first time users is to offer a free version of a service that has limited functionality and once you’ve got them hooked provide an easy way to upgrade and pay for more features. This Web Application Toolkit offers a more elegant and cost-effective way to solve this problem.
• Calendars - This Web Application Toolkit provides a standards-based service that can be reused in your own Web application to expose calendaring and events information for different users, using different data formats (iCalendar, XML, JSON) using REST.
• Bing Maps - A set of reusable custom controls built in Silverlight, which integrated with the Bing Maps Silverlight Control, make a perfect fit for some of the most common location-aware scenarios.
• Bing Search - 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.

There quite a few more around IE8, Mobile apps, Template Driven Email, and more.
