【Original publication date】 Monday, February 08, 2010 11:39 PM
[In addition to blogging, I now use Twitter to post short posts and share links. Please follow me at twitter.com/scottgu. 】
This afternoon we released VS 2010 and .NET 4 RC (final release candidate), you can find the download link here.
Currently, downloads are only available to MSDN subscribers. As of Wednesday (February 10), it will be available for download by everyone (regardless of whether you are an MSDN subscriber or not).
The Origin of the RC Version In December last year, I wrote in my blog that we decided to release a public RC version of VS 2010. The main motivation behind releasing a public RC version was to ensure that we could continue to improve the performance since the last public VS 2010 Beta 2 version. The performance and stability work we do is subject to extensive testing and feedback.
Over the past few months, we have been releasing mid-term releases to a small group of people who have been helping us validate bug fixes and measure very large projects and initiatives. Their feedback over the past few weeks has been overwhelmingly positive, which is why we’re opening today’s version up to a wider group of people to try.
The RC version has only been out for a few hours so far, but the feedback on Twitter looks promising:
@DanWahlin: Visual Studio 2010 RC version has huge performance improvements compared to previous versions. So happy with everything I've seen so far.
@peterbromberg: I must admit that I am very impressed with the VS2010 RC version. The major speed and performance improvements are so obvious!
@Nick_Craver: The performance of the RC version is ridiculously fast. I can’t wait. I want to switch to it now and use it full time!
@Rlz2cool: I just tried the VS2010 RC version. To describe it in one word, it’s incredible and super fast. This version is great. Everything I saw in the previous version has been fixed. It’s awesome.
@ddotterer: I tried the VS2010 RC version. The interface is really beautiful, intellisense is much faster, the compilation time is greatly reduced, etc. Overall impression: Awesome!
@tomkirbygreen: OMG VS2010 RC is so much faster, hats off to the VS Performance team and others for uninstalling Visual Studio 2008 :-)
@JoshODBrown Visual Studio 2010 RC developers must have swapped their usual drinks for Unicorn Tears or something, #VS2010 #awesome (so awesome!)
@jbristowe: Holy Butterball! VS 2010 RC is insanely fast and it makes me feel like this: http://bit.ly/cPaOvE
Reporting Issues Our goal with today's public release of the RC version is to get a lot of eyes (eyes) on our product and help us find and report remaining bugs that we need to fix. If you find an issue, please submit a bug report through the Visual Studio Connect website, or send me an email directly ( [email protected] ) with the details of the issue, and I can forward your email to someone to do it. Research and trace directly (this can help speed up the identification of the problem).
If you have installed and used the VS 2010 RC version, we would be very grateful if you could fill out this survey about your experience.
Replies to several inquiries and known issues
Here are a few responses to some inquiries/known issues:
If you have previously installed VS 2010 Beta 2 on your machine, you should use "Add/Remove Programs" (in the Windows Control Panel) to uninstall VS 2010 Beta2 and .NET 4 Beta2 before installing VS 2010 RC version. Note that the VS 2010 RC version can be installed side by side with VS 2008 and VS 2005 on the same machine.
Silverlight 3 projects are supported in today's VS 2010 RC version, but Silverlight 4 projects are not yet supported. We will add support for SL4 in VS 2010 RC in the next public Silverlight 4 release. If you are actively developing Silverlight 4 today, we recommend that you continue to use the VS10 Beta 2 version.
We recently discovered a crash flaw that affects multi-touch and some screen reader-enabled systems, and we are preparing a patch for those affected.
We recently discovered an issue where when a project is upgraded from VS 2008, it takes a long time to complete if the project contains .xsd files. If you think VS is taking a long time to upgrade your project, give it a few more minutes before assuming the program hangs. You may be experiencing this slow upgrade problem. Note that once the project is upgraded, performance should return to normal. We are working on fixing this flaw in the final version.
Hope this article is helpful to you,
