Here is another interesting virtual machine. The Visual Studio team have made Beta 1 of the next release of Visual Studio (codenamed ‘Orcas’) available as a virtual machine. It is quite a large download – but it provides a relatively easy way to checkout the beta without messing up your existing development environment.
One thing to note – the default configuration only has 384mb of memory configured for the virtual machine. You will want to increase that if you have enough physical memory in your computer.
