LINQ defines standard query operators that allow code written in LINQ-enabled languages to filter, enumerate, and create projections of several types of collections using the same syntax. Such collections may include arrays, enumerable classes, XML, datasets from relational databases, and third party data sources. The LINQ project uses features of version 2.0 of the .NET Framework, new LINQ-related assemblies, and extensions to the C# and Visual Basic .NET languages. Microsoft has distributed a preview release of LINQ, consisting of those libraries and compilers for C# 3.0 and Visual Basic 9. Other languages, such as F# and Nemerle, have also announced preliminary support.

The .NET Framework 3.5 provides the foundation for building connected and appealing applications, productively, on a wide variety of systems from the device to the data center.

Microsoft continues to support developers using the .NET Framework platform by providing support for applications built in previous versions to the 3.5 release, so existing applications built for .NET Framework 2.0 or .NET Framework 3.0 will continue to work.

The .NET Framework 3.5 adds new features in several major technology areas:

• Deep integration of Language Integrated Query (LINQ) and data awareness.
• Support for Web 2.0 AJAX-style applications and services in ASP.NET and WCF.
• Full tooling support for WF, Windows Communication Foundation (WCF), and Windows Presentation Foundation (WPF), including the new workflow-enabled services technology.
• New classes in the base class library (BCL) for the .NET Framework 3.5 address the most common customer requests.

Microsoft Windows Services is the engine that allows administrators to create Web sites for
information sharing and document collaboration. Windows SharePoint Services provides
additional functionality to the Microsoft Office System and other desktop applications, as well as
serving as a plat form for application development. SharePoint sites provide communities for team

collaboration, enabling users to work together on documents, tasks, and projects. The environment
for easy and flexible deployment, administration, and application development.

SharePoint Portal Services (SPS) has MUCH better document management. It has check-in,
check-out, versioning, approval, publishing, subscriptions, categories, etc. STS does not have
these features, or they are very scaled back. SharePoint team Services (SPS) has a better search
engine, and can crawl multiple content sources. STS cannot. STS is easier to manage and much
better for a team environment where there is not much Document Management going on. SPS is
better for an organization, or where Document Management is crucial.

Structured Query Language. The standardized relational database language for defining database objects and manipulating data.
