Microsoft confirmed that "Visual Studio 2012 RTM will not install on a pre-release versions of Windows 8 or Windows Server 2012."

"Customers installing Visual Studio 2012 RTM on pre-release versions of Windows 8 or Windows Server 2012 may see the following error after launching the setup application: The .Net Framework installed on this machine does not meet the minimum required version: 4.5.50709."

"This is a blocking error and only allows the install to be canceled," Microsoft stated.

To install Visual Studio 2012 RTM, "you will need to install it on Windows 7 SP1, Server 2008 R2 SP1, or install VS2012 RTM on Windows 8 or Server 2012 RTM," Microsoft said.

If you are an MSDN or TechNet subscriber, you can get Window 8 now from the following link.

Those, who are not an MSDN or TechNet subscriber, can download a 90-day evaluation of Windows 8 Enterprise.

You may also continue to use pre-release versions of VS2012 on supported pre-release versions of Windows 8, such as VS2012 RC on the Win8 Release Preview (RP).

Visual Studio 2012 Debugging Features for the Windows 8 App Lifecycle Model

Windows 8 brings a new app lifecycle model, in which Windows Store apps are automatically managed for the user. These apps always feel alive, even though they never run when they're off the screen. This provides great benefits for power consumption and battery life.

In a blog post, Microsoft discuss at what this all means for debugging. "Of all the debugging advances we made in Visual Studio 2012 (from JavaScript debugging, to the Windows 8 Simulator, to remote debugging on Windows RT devices), the debugging experience for Windows 8 lifecycle states and background tasks was one of the most challenging to design!," Dmitri Leonov - Software Development Engineer in Test, Visual Studio Ultimate team, posted.

The Windows 8 app lifecycle model "presents some new debugging scenarios to consider, as you develop your Windows Store apps. Using Visual Studio 2012, you can simulate the events and states that your app will encounter, as it gets suspended and resumed. Visual Studio 2012 also provides a way to debug different app activation mechanisms, by putting the package in debug mode without activating the app. Finally, you can use the Debug Location toolbar dropdown to trigger background tasks," Leonov explains.

For more information on this topic, refer this MSDN documentation, or read the Leonov's blog post here.

Finally, a TechNet post titled "Windows Server 2012 Scale-Out File Server for SQL Server 2012 - Step-by-step Installation" offers the resources to accomplish the task.

The document sharing all the steps used to create a Windows Server 2012 File Server demo or test environment. You only need a single computer and the ISO file with the Windows Server 2012 evaluation version. For the SQL part, you will need the SQL Server 2012 evaluation version.

"The demo setup includes 4 virtual machines: one domain controller and iSCSI target, two file servers and a SQL server. You need the iSCSI target and two file servers because we're using Failover Clustering to showcase SMB Transparent Failover and SMB Scale-Out. We'll also use multiple Hyper-V virtual networks, so we can showcase SMB Multichannel," wrote Jose Barreto.

You can download Windows Server 2012 Evaluation ISO file here. And, SQL Server 2012 Evaluation ISO is avialable for download here.
