Visual Studio Web Publish Update
Visual Studio 2012 and Visual Studio Express 2012 for Web offer improved web publish (deployment) features for web application projects. The new features are installed by default but are optional and can be disabled during product installation. If you disabled them during product installation but decide you want to enable them, you can do that by installing the Web Publish Update.
The same web publish features that were introduced in Visual Studio 2012 can also be enabled in Visual Studio 2010 and Visual Web Developer 2010 Express by installing the Web Publish Update.
Not
Installing the Web Publish Update in Visual Studio 2010 or Visual Web Developer 2010 Express enables the new features in the product but does not update the Visual Studio 2010 documentation. After you install the Web Publish Update, use Visual Studio 2012 (.NET Framework 4.5) documentation for deployment features.
Installing the Web Publish Update
Choose the link that corresponds to your Visual Studio version:
Windows Azure SDK for .NET (VS 2010 SP1) for Visual Studio 2010 and Visual Web Developer 2010 Express.
Windows Azure SDK for .NET (VS 2012) for Visual Studio 2012 and Visual Studio Express 2012 for Web.
These links use the Web Platform Installer (WebPI) to install the web publish features and all of their dependencies. Although the title of the WebPI package is Windows Azure SDK, the SDK is only part of the package. Most of the items that the package installs are required for the web publish features.
