In addition to all of the new functionality that we can now start playing with (listed below),  this CTP release is also exciting in that it is very conveniently available as both a self-extracting installation and also as a Virtual PC image - thanks Microsoft !

Here are the highlights of this CTP, from the download page:

• Extended, more powerful data APIs with the ADO.NET Entity Framework and LINQ to ADO.NET
  • 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.
  • 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.

• 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

• VB 9.0 Language Support: This CTP implements all of the VB 9.0 language features from the May LINQ CTP including:
  • Query Expressions
  • Object Initializers
  • Extension Methods
  • Local Variable Type Inference
  • Anonymous Types

• 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. Click here for more details about LINQ.

• ClickOnce improvements
  • This CTP delivers ClickOnce improvements for the deployment of Windows Presentation Foundation applications, alternative browser support and ISV rebranding.

• Managed classes for Elliptic Curve Diffie Hellman and Elliptic Curve Digital Signature Algorithm cryptographic functionality
  • With the addition of these classes, cryptographic developers now have managed classes for Elliptic Curve Diffie Hellman secret agreement and Elliptic Curve Digital Signature Algorithm signing. These classes are built on the new CNG cryptographic libraries in Windows Vista, but still follow the familiar patterns of the cryptographic classes in .NET Framework 2.0.

• Runtime and design-time support for Office 2007 (including Outlook 2007)
  • Customers can build managed code add-ins with a consistent development experience, regardless of which version of Office they target, which Office application(s) they target, and which programming language they choose. Managed code add-ins enable developers to use strongly-typed class members, with the help of modern development tools, including intellisense and auto-complete. Additionally add-ins can potentially run in multiple versions of Office, enabled by abstracting version-specific code and supported by a version-resilient infrastructure.

• Support for advanced lifetime management of add-ins and their AppDomains
  • We’ve added the helper classes that manage the lifetime of add-ins, the objects passed between the host and add-ins, and even of the AppDomains the add-ins live in. By using the ContractBase and LifetimeToken handle, pipeline developer can let the hosts and add-ins act as if everything, including the AppDomain the add-in was activated in, was controlled by the garbage collector even though .Net Remoting would normally make that impossible.

• Client service support for Login/Logout, Role management and Profiles
  • ASP.NET 2.0 shipped with new application services for authentication, authorization and personalization. Most of these services are not tied to ASP.NET and can work in non-web applications. This CTP enables the use of these services in smart client applications for Logon/Logoff, Role management and profiles.

• A trace listener that logs event to ETW, event tracing for Windows in Vista
  • Event tracing for windows is greatly improved in Vista and the most performant loggings facility available in Windows. The System.Diagnostics.EventProviderTraceListener allows managed tracing to provide events to the Vista’s ETW infrastructure. This is a highly performant, thread-safe listener.

• Jscript Intellisense support
  • Jscript code formatting and Intellisense support provide developers with a richer editing experience. These improvements enable the IDE to provide statement completion, color syntax highlighting and in-place documentation to Jscript and associated script models such as ASP.NET AJAX.

• A new numeric type that provides support for very large numbers (Beyond the range of In64)
  • All existing numeric types in the Framework have a limited range. This is the first type that supports arbitrary range and will extend to accommodate any large number as needed. This type lives in the new System.Numeric namespace where all new numeric and arithmetic features are going to reside. It supports all the basic arithmetic operations including things like Pow, DivRem and GreatestCommonDivisor. It implements the following interfaces: IFormattable, IComparable, IComparable<BigInteger> and IEquatable<BigInteger>. It is serliazable and immutable. It has implicit casts from all basic integral types and explicit casts to/from all numeric type. To learn more about this type – please visit the BCL team blog.

• LINQ over XML (XLinq)
  • Enable further LINQ over XML feature support (in addition to the functionality available in the Oct 2006 CTP) such as the ability to apply XLST to transform into and out of XLinq trees, support for System.XML reader/writer interfaces for improved XML sharing with DOM applications and System.XML schema validation for XLinq nodes.

• SQL Server Compact Edition (SSCE)
  • SQL Server Compact Edition (SSCE) provides a local relational data store for occasionally connected client applications from desktops to devices. SSCE is light weight, embeddable and is easy to deploy with your client applications without requiring complex administration work from users. Timestamp (row version id) data type, improved table designer, Query processor enhancements and support for local transaction scope are some of the new features you find in this version of SSCE.

Well, thanks to André Obelink, I've been tagged and am now a participant in the blogsphere version of Tag, as started by Jeff Pulver and explained here.

So here are 5 things I am pretty sure you don't about me:

(1) Although I am NOT someone who is necessarily impressed by degrees (I care much more about actual accomplishments), I have completed 3 Masters degrees.   I have a Bachelors degree in Electrical Engineering from The Cooper Union.  I stayed on to complete a Masters degree in Electrical Engineering there as well, mainly because I was just getting into Microprocessors and software.   After that, when it was obvious to me that I was going the software route (rather than hardware), I completed a Masters degree in Computer Science at Polytechnic University (while already working full).  Finally, I continued my evening education at Polytechnic, in order to complete a Masters degree in Management.   It often amazes me how much I USED to know :-)

(2) Before becoming immersed in the Windows world, I spent 10 years developing Microprocessor-based and Real-time Software.  I regularly note the irony in the fact that my current main area of expertise (database access) is one that I used to make fun of.

(3) As a youth and young adult (through college) I was a real hockey fanatic.  I played hockey in all of its forms: street hockey, field hockey, roller hockey, and ice hockey.  I was the captain of my high-school hockey team, and ran into some "issues" with Algebra, since my Final exam was scheduled right after one of our playoff games - which would have been fine if the game hadn't gone into overtime !

(4) At the age of 30, I ran the New York City Marathon in a time of 4:52.  Yes, I realize that you wouldn't believe that looking at me today :-(

(5) I am a big fan, consumer, and student of single-malt scotch.  That probably explains something...

I am going to tag Dan Appleman,  Shy Cohen, Barry Gervin, Kim Major, and Brian Randell

The final bits of SQL Server 2005 Compact Edition 3.1 have been released and are available for download here. 

Having worked with and given numerous conference and User Group presentations with the RC and the previous edition (known as SQL Server 2005 Everywhere - see previous blog entry), I am very excited about this product and urge you to check it out.  Remember, this powerful, light-weight database engine is now available for your desktop applications as well as mobile devices.

On January 31, Microsoft Israel is running its biggest event ever for developers and architects (and their managers).  Under the slogan of "Microsoft Developer Academy", there are 5 session slots over the course of the day, each with 5 sessions to choose from.   For various reasons, I had to bow out of my speaking at this event, but you should definitely register right away before registration is all filled up.  Register here (Hebrew)

Before you go out and buy that new laptop you promised yourself, be sure to first read this article by Kim Major.  It is actually a series of 3 blog posts, that run through his considerations and conclusions before replacing his existing Thinkpad.
