February/March Orcas CTP Now Available

The February CTP (aka as the March CTP) is now available for download as a regular install and as a virtual PC. Here is a video that serves as an introduction to the CTP.

This CTP is a pre-release version of Visual Studio Orcas. This release features support for LINQ to SQL, which means you can use LINQ to query relational databases.

There were a few issues with this CTP when running on Vista, and when running side by side with Visual Studio 2005. As a result, if you have VS 2005 installed, or if you are running on Vista, then I would suggest using the VPC version of this download. When downloading the VPC version of Orcas, don't forget to get the base image.

Here is a link to various LINQ related articles and posts, and be sure also to see this post which details many of the changes since the May CTP. Here is a link to videos and articles that I have written on LINQ.

Here are some Anders videos from Tech Ed Barcelona:

  1. LINQ Overview
  2. C# 3.0

Here are few other LINQ related videos to help you get started:

  1. Anders on LINQ and Functional Programming
  2. Anders on Ask the Experts, Jan 17, 2007
  3. Anders on LINQ from 2005
  4. Anders on LINQ from the LANG.NET Conference
  5. Anders Chatting about LINQ and ADO.NET
  6. Anders, Herb Sutter, Erik Meijer, Brian Beckman on Software Composability
  7. Anders with Chris McConnell
  8. Eric Lippert on Type Inference
  9. Peter Hallam on Automatic Properties
  10. Performance Issues in Visual Studio (Anson Horton, C# PM, only tangentially related to LINQ)
  11. Luca Bolognese (Lead PM, C# Team) on "What's New in the May LINQ Preview"
  12. C# PM's Karen Liu and DJ Park on the C# IDE, LAF, and support for LINQ.
  13. An Interview with Wes Dyer (Download)
  14. Raj Pai, C# GPM, on the C# Team

Here are some specs to review:

  1. Formatting Code in Orcas
  2. DLINQ Data Types and Functions
  3. Mapping Draft Specification

A good news. Much interested in this topic and got a chance to tryout the earlier version. Expecting  more stable one now with more features.

Just watched the CTP video.

Karen is HOT!!

Now to my question.

Stop hoarding your language and IDE to just SQL Server.

We(my company) will never use SQLServer (SS), but most of your database features only work WELL with SS.

We are now starting to look at Borland (CodeGear) again, after we just left them, because they don't design their IDE to be specific to any particular database. And if a driver doesn't exist, you build one yourself.

# re: February/March Orcas CTP Now Available

Thanks for doing this!!  I know we get release notes with every drop, but in some ways this is a lot more effective at communicating what's new, what's changed, etc.  For example, knowing that 700,000 QA tests were done with Linq to SQL since the May bits, or that intellisense has been gutted and rebuilt.

I do wish they had talked a bit on ADO.NET Entity Framework though.  Specifically, how it relates/compares/competes to/with Linq to SQL, and what the story looks like for using either of these technologies in a tiered environment where I'm not just hitting up SQL Server directly from my WinForms app...

Hi,

thanks for the information.

But, how can I create a DVD out of this?

Thanks.

# re: February/March Orcas CTP Now Available

We are real excited about Linq as this is a large T-SQL shop stuck in SQL Hell and this stuff looks like our future. However we have run into an issue with UDFs as no matter how simple they are an exception "object reference not set to an instance of an object" is thrown. The problem seems to lie in the return type as in code :

object test = db.getRate(serviceid)

gerrate is a UDF with a return type of decimal not object (have no idea why this would throw as object is the base type in CLR). However in the designer.cs the return type is object thus the above line .When we change object to decimal in the designer.cs file then things work as expected. of course this is not a great solution as the generated code must be updated each time a change is made in the designer.

# re: February/March Orcas CTP Now Available

Regarding this quote...

"Stop hoarding your language and IDE to just SQL Server."

I attended a seminar on DLinq with Scott Guthrie, and I fielded this exact question to him.

They actually aren't supporting SQL Server exclusively.  However, that particular provider is the only one they (M$) are developing and distributing with the DLinq framework.  

The provider model is basically a published API that any database server software publisher can utilize to make plug-ins to the DLinq framework.

So.. the ability is there.  The competitors just haven't taken it up yet.  If they don't, I imagine at some point, an ISV will do it.

Charlie,

Is it possible to have a complete list of all the LINQ related videos/interviews till date so that there is one place to download all of them from instead of going video hunting all over the place.
