Several CTPs for Visual Studio 2014 have been released so far. The 3rd and 4th CTPs can be actually used with a Windows Azure Virtual Machine. If you have a Windows Azure account you can go ahead and create a VM. If you are an MSDN Subscriber or you have a trial account, you have a number of free hours that you can use, so you won’t have to pay anything to run VS2014 CTP in the clound.
NOTE: Details about the limits and cost in Windows Azure are available here (also see this article).
Below is a step-by-step walk through of how to create and start a VM for Visual Studio 14 CTP 4.
Step 1: Log to Windows Azure.
Step 2: Create a new virtual machine.
In the Azure portal press the New button.
Select Compute > Virtual Machine > From Gallery
Choose the Visual Studio 2014 CTP 4 Image
Select the virtual machine configuration
Step 3: Wait until the virtual machine starts up.
Step 4: Connect remotely to the virtual machine.
See How to Log on to a Virtual Machine Running Windows Server.
Note: You have to authenticate with the username (make sure you use the format machinename\username) and the password you have created, not the account you are initially prompted in the RDP window.
Step 5: Launch and use Visual Studio 2014 CTP.
