Microsoft has released a community technology preview (CTP) for Visual Studio 2012 Update 3

Visual Studio 2012 Update is providing continuous value to customers, adding new capabilities year-round to features in the main product release. These releases will be aligned with the core software development trends in the market, ensuring developers and development teams always have access to the best solution for building modern applications.

This is a community technology preview (CTP) for Visual Studio 2012 Update 3. These cumulative updates to Visual Studio 2012 include a variety of bug fixes and capability improvements. More details can be found here.

Statement of Support:

PLEASE NOTE: This Technology Preview has not been subject to final validation and is not meant to be run on production workstations or servers. Due to a limitation in this preview, Internet access is required during installation, even when installing with the /layout option. Please ensure Internet access is available before installing this update. Since installation of Visual Studio CTPs and installation of Team Foundation Server CTPs work differently, please read the recommended upgrade approach for each product carefully.

For Visual Studio: The recommended approach for upgrading Visual Studio on test workstations is installing the latest Visual Studio Update CTP on top of an RTM release or a previous CTP build of that Update. Visual Studio CTPs can be upgraded to a different build.

For Team Foundation Server: Do not install a Team Foundation Server Update CTP on a production server, as it will put the server in an unsupported state. Unlike with Visual Studio CTPs, installing a Team Foundation Server CTP fully replaces the current release on the server with the CTP. Team Foundation Server CTPs cannot be upgraded to future CTPs or releases nor “downgraded” to a previous release.
