The March CTP (community technology preview) of Visual Studio Orcas is now available here. You can either install it (side-by-side with VS 2005) or use via a VPC image. This is the first CTP that contains significant web tools feature enhancements – the new HTML/Webforms Designer, Jscript Intellisense and Debugging, LINQ to SQL Designer and Multitargeting being some of the key features. You can learn more about these features from this blog post by Scott as well as this forum post by Jim.
We encourage all of you to try out the CTP and provide us early feedback that will help shape the rest of this release. We have created a new forum for you to post your questions and suggestions regarding the feature set. Team members will be regularly reading the forum posts and will respond to you. Bugs can be submitted here. We look forward to getting as much feedback as possible in order to build the best product for you!
