Visual Studio 2012 Update 1, is now available. You can install it today from the download page (see "Visual Studio 2012 Update 1" under the "Additional software" section).
With this and future updates, we’re striving to ensure that developers and development teams always have the best solution for building modern applications and for managing the modern application lifecycle. This approach to delivering updates, integrated directly into the IDE, should make it much easier for developers to keep the Visual Studio client up-to-date.
Importantly, this isn’t just about bug fixes, though it contains quite a few of those to measurably address issues reported through Connect, UserVoice, and Windows Error Reporting. This update also delivers a wealth of new functionality into Visual Studio 2012.
The new functionality in Update 1 primarily spans four areas of investment:
1. Windows development,
2. SharePoint development,
3. Agile teams
4. Continuous quality.
