A 7 day trial of .NET Demon is available to download for free.
The background compilation will use up your computer's resources, but your coding will speed up a lot! The change in performance will be minimal if you have a multi-core machine.
Visual Studio compiles the project you changed, and all projects that depend on it.
.NET Demon checks whether there are changes to the public interface of the project: if not, there's no need to compile projects that depend on it.
No. You can continue using Visual Studio as usual. The only changes you will experience will be faster builds and the live feedback about compile errors.
Unfortunately, yes, VB.NET Edit and Continue doesn't work with .NET Demon. C# Edit and Continue works fine.
Yes, .NET Demon can compile Silverlight applications. However, getting the updated .xap file to the right ClientBin folder is not 100% reliable. Try right clicking on your solution, and using Project Dependencies to make your web project depend on the Silverlight project.
Installation and uninstallation is controlled by Visual Studio. You can find .NET Demon in Tools -> Extension Manager and configure it there.
Neptune is the internal codename for .NET Demon.
