Orcas release date, first estimates

Roger Jennings has spotted very interesting information on Scott Guthrie's weblog. It's not like there is anything but excellent content on Scott's blog, but I haven't seen this kind of information elsewhere before.
Scott has published a first post on using LINQ with ASP.NET projects a few days ago. Roger writes:

Scott's LINQ with ASP.NET post provoked a large number of comments and replies, but the most interesting reply included this gem:
We are looking to ship the second half of next year. We will start having full Orcas CTP drops (of all technologies) starting later this summer, and will also have a go-live license of Orcas before the final RTM date. So not too far off now when you can use the above techniques in production.
This is the first Orcas RTM estimate and go-live committment directly from a Microsoft employee that I've encountered.

If you browse the whole set of comments, you may spot other related information, which includes:
  • "We are making some changes to the CLR for that release, but are also being careful to keep a high runtime compat bar to ease deployments (the following release will then have more engine additions)."
  • "Orcas will be compatible with the 2.0 runtime. There will then be optional framework components you can install as well."
This confirms that one of the design goals for LINQ is still to keep it compatible with .NET 2.0. What's new to me is that Microsoft is trying to keep the changes to the .NET runtime very light for the next release.


  • Fabrice,

    We like Scott. Please dont try to get him in trouble with the exec team at Microsoft.

    Scott really has not told as anything new that wasnt already public information. ;-)

  • you are quite the detective!

    is this forensic blogging?


  • Everything you'll say will be recorded and analyzed... and misused ;-)

  • I don't think he's saying that LINQ will run on 2.0. He is saying that Orcas, the development environment, will be compatible with the 2.0 framework. At the very least this means you can target the 2.0 platform, but it doesn't say whether the new CLR would be required if you use the new features (I would think yes).

  • Just a small remark: It might be usefull to put a timestamp to your article. As estimations on the release date of next year are quite useless, if one can only guess that your wrote it this year or last year...

  • Martin, which article are you talking about? I see dates in all of the blog posts I link to as well as in this post.

  • That's right. Visual Studio 2008 (Orcas) is planned for the end of 2007.
