ADO.NET Entity Framework
The Entity Framework is the preferred method of data access for .NET applications, supporting strongly-typed access through LINQ. The Entity Framework also allows developers to program against a conceptual model that reflects application logic rather than a relational model that reflects the database structure. The Entity Framework can also be used from an ASP.NET application through the Entity Data Source.
WCF Data Services
Data Services enable you to expose data models to the Web in a RESTful way, with rich built-in data access capabilities such as flexible querying, paging, and association traversal.

.jpg "There is no shortage of valuable data being generated by applications, reports, tools, websites, etc. Unfortunately, this leaves many of us wishing we could programmatically access the data and logic behind an app, report or website. To break down data silos and increase the shared value of data and its asscoiated business logic through the web, Microsoft has recently announced the Open Data Protocol which enable exposing any data source as a web-friendly data feed. Join this session to understand what the Open Data Protocol (OData) is and how it adds end user and developer value to many of Microsoft's leading products and services (such as SharePoint Server 2010, Microsoft Codename \"Dallas\", Windows Azure, SQL Server Reporting Services, SQL Server PowerPivot for Excel, Visual Studio, .NET, Silverlight, AJAX etc.) and is accessible from a range of platforms such as Java and PHP.")
