Beberapa fitur yang tersedia diantaranya:

• LINQ
  The LINQ Project: this CTP represents a major milestone in the LINQ project. For more information about LINQ click here.
• VB 9.0 Language Support: This CTP contains the following language features:
• Query Expressions: Basic querying, filtering, and ordering support
• Object Initializers
• Extension Methods
• Local Variable Type Inference
• Anonymous Types
• XML literals
• XML properties
• New Line and Expression IntelliSense

• C# 3.0 Language Support: This CTP implements all of the C#3.0 language features from the May LINQ CTP including:

  • Query Expressions
  • Object and Collection Initializers
  • Extension Methods
  • Local Variable Type Inference and Anonymous Types
  • Lambdas bound to Delegates and Expression trees
  • Complete design-time support: Intellisense, Formatting, Colorization
• LINQ to ADO.NET
  • ADO.NET is fully integrated with LINQ and offers many options for using LINQ in various scenarios: LINQ to SQL provides direct access to database tables from the programming environment, LINQ to Entities enables developers to use LINQ over EDM models, and LINQ to DataSet allows the full expressivity of LINQ to be used over DataSets.
  • LINQ to Entities enables developers to program against a relational database using a view of the data that is appropriate for the application they are building, independent of the structure of the underlying database. The use of the Entity Data Model (EDM) enables developers to design models that follow the concepts built into the application, instead of having to map them to constructs available in relational stores. LINQ to Entities is built on the ADO.NET Provider model and will support working against different back end relational stores in addition to Microsoft SQL Server. This CTP includes a LINQ to Entities provider for SQL Server and SQL Server Compact Edition.
  • LINQ to SQL (previous name DLinq) has enhanced the functionality from the May 2006 LINQ CTP. You can find it in System.Data.Linq namespace in System.Data.Linq.dll. New in this release is that DataContext provides optimized modes for read-only use and serialization . Also new is that DataShape streamlines eager loading capabilities and adds the ability to set queries on relationships
• LINQ To SQL Designer
  • Methods can be created from stored procedures and functions within the designer.
  • Better handling of database schemas.
  • Improved inheritance support in the designer.
• LINQ over XML (XLinq)
  • System.Xml Bridge Classes added – There is a set of extension methods allowing XPath / XSLT to be used over LINQ to XML trees, allow XSLT transformations to produce an LINQ to XML tree, and to validate an XElement tree against an XML Schema.
  • Event Model - This allows LINQ to XML trees to be efficiently synchronized with a GUI, e.g. a Windows Presentation Foundation application
  • Class hierarchy changes - XObject class added, XStreamingElement class (temporarily) removed
  • Various understandability / usability improvements – There have been a number of relatively minor changes done in response to internal reviews, usability studies, and external feedback to make the API more clean and consistent.
• LINQ to Objects API
• The LINQ to Objects API supports queries over any .NET collection, such as arrays and Generic Lists. This API is defined in the System.Linq namespaces inside System.Core.dll.
• ADO.NET
  • Extended, more powerful data APIs with the ADO.NET Entity Framework
    • With the ADO.NET Entity Framework developers will be able to model the view of the data that is appropriate for each one of the applications they are building, independently of the structure of the data in the underlying database. The use of the Entity Data Model (EDM) enables developers to design models that follow the concepts built into the application, instead of having to map them to constructs available in relational stores. Once the model is in place, the powerful ADO.NET Entity Framework API is used to access and manipulate the data as .NET classes or as rows and columns, whatever is appropriate for each application.
  • Added paging and stored procedures for update (“update customization”) for ADO.NET Entity Framework:
    • Paging: the paging support in the ADO.NET Entity Framework allows developers to “page” over data in a database by indicating the start row and number of rows to be included in the result. Paging is available through Entity SQL (using the LIMIT AND SKIP keywords) and through the query-builder methods in the ObjectQuery &ltT> class (Top and Skip). In a future CTP the feature will also be enabled to be used in LINQ queries by means of the standard Take and Skip LINQ operators.
    • Stored-procedures for update customization: the Entity Framework by default automatically generates SQL statements for insert, update and delete operations when processing changes to entities in memory to be sent to the database. With the stored-procedures update customization feature developers have the option to override the automatic SQL generation and instead provide stored-procedures that will perform the insert, update and delete operations, which the system will call during entity change processing. Among other things, this enables scenarios where direct access to tables is restricted in the database and the only way to make changes to the data is through stored-procedures.
  • Microsoft Synchronization Services for ADO.NET
    • Provides an application programming interface (API) to synchronize data between data services and a local store. The Synchronization Services API is modeled after the ADO.NET data access APIs and gives you an intuitive way to synchronize data. It makes building applications for occasionally connected environments a logical extension of building applications where you can depend on a consistent network connection.

  • Performance tune an enterprise application
    • Enables developers to run profiling during load and test procedures for a system, to see how it behaves, and use integrated tools to profile, debug and tune. This also enables performance base-lining, so that users can save a baseline profile and then, if the performance degrades, compare up-to-date traces to identify the source of the regression
• Team Test
  • Unit Test Generation Improvements
    • Improvements to unit test generation provide an easy way for the user to specify what methods to test, and generate test methods and helper code to do unit testing, as well as providing unit test support for generics.
  • Web Test Validation Rule Improvements
    • Web Test rules improvements enable testers to create more comprehensive validation rules for the application being tested. These improvements include the following functions:
      • Stop test on error
      • Search request and response
      • Add validation rule for title
      • Redirect validation

  • Improved Load Test Results Management
    • With this feature user can open or remove an existing load test result from the load test repository. User can also import and export load test results files.
• Team Foundation Server
  • Team Build
    • Support multi-threaded builds with the new MSBuild.
    • Continuous Integration – There are many components to this, including build queuing and queue management, drop management (so that users can set policies for when builds should be automatically deleted), and build triggers that allows configuration of exactly how when CI builds should be triggered, for example – every checkin, rolling build (completion of one build starts the next), etc.
    • Improved ability to specify what source, versions of source, etc to include in a build.
    • Improved ability to manage multiple build machines.
    • Simplified ability to specify what tests get run as part of a build
  • Version Control support
    • Destroy- The version control destroy operation provides administrators with the ability to remove files and folders from the version control system. The destroyed files and folders cannot be recovered once they are destroyed. Destroy allows administrators to achieve SQL server disk space usage goals without constantly needing to add more disks to the data tier machine. Destroy also facilitates removing versioned file contents that must be permanently removed from the system for any other reason.
    • Annotate - Annotate is a feature that allows developers to inspect a source code file and see at line-by-line level of detail who last changed each section of code. It brings together changeset data with difference technology to enable developers to quickly learn change history inside a source file.
    • Folder Diff - Team Foundation Server now supports compare operations on folders, whereby the contents of the folder are recursively compared to identify files that differ. Folder diff can compare local folders to local folders, local folders to server folders, and server folders to server folders. It’s a great way of identifying differences between branches, files that you’ve changed locally, and files that have changed between two points in time.
    • Get Latest on Checkout - As an optional setting on a team project or on an individual basis, you can have Team Foundation Server always download the latest version of a file when you check it out. This helps ensure that you don’t have to merge your changes with somebody else’s when you check the file back in.
  • Performance and Scale
    • This release includes numerous improvements in performance and scalability of Team Foundation Server.
• Visual C++
  • Easily add the Windows Vista “Look and Feel” to native C++ applications
    • Developers can use Visual Studio to build ISV applications that exhibit the Windows Vista “look & feel”. A number of the Windows Vista “look & feel” features are available simply by recompiling an MFC application. Deeper integration that requires more coding or design work on the part of the developer is also simplified with Visual Studio’s integrated support for the Windows Vista native APIs.
