Visual Studio 2010 and ASP.Net 4.0 (Beta1)
The public release of Visual Studio 2010 Beta 1 is now available and can be downloaded here.
This is one of the most compelling updates to Visual Studio we’ve seen in years. The entire IDE has been refreshed with a new look and all the code editors including the HTML and ASPX editors have replaced with a new extensible editor based on WPF.
One of the reoccurring themes throughout Visual Studio 2010 is developer productivity. For example integrated into the new code editors is a consume first workflow where you can start calling methods on classes even before they exists. Then you can have VS generate the new code extending the class as you type.
Community is another theme in Visual Studio. Integrated into the new project and new item dialogs is the Visual Studio Gallery containing templates from the community. There is also an Extension Manager that makes it easy to add community developed extensions to Visual Studio.
A good overview of the breath of new features in Visual Studio 2010 can be found on Jason Zander’s Blog.
New for the Web
- A new editor for web developers with code-focused productivity through HTML/ASP.Net snippets

For example field validation can now be added in just a few key strokes. After the snippet is inserted you’ll only need to fill-in the unique pieces of information highlighted below.

Packaging and Deployment
Visual Studio 2010 now has the ability to completely package and deploy a web application including all it’s IIS settings, Databases and Application logic.
|There is a new 1-click publishing experience that simplifies publishing and updating your sites.
In addition to 1-click publishing there are extensive packaging options to control what specific IIS settings you want included with your package.
You can even include custom database scripts to run when your package is installed.
As part of the packaging process you can also run custom transforms on web.config that allow you update any section of web.config with custom settings unique to the deployment.
For example you can replace database connection strings and web service end points.

CSS 2.1 Layout Rendering in Design View
The HTLM and ASPX designer has been updated with support for CSS 2.1 layout rendering including attribute selectors. The designer will now faithfully render your CSS 2.1 standards compliant markup.
