Sub Versions are a nice way to manage and Edit a Project as a team. An SVN repository contains the complete code which is to be managed and different people have different rights on accessing and changing the code. These SubVersions consist of various check points when the code was in a commit state and we can edit these versions or rollback to the previous stable versions and work on them. Hence these repositories help us in managing the code effectively in case a wrong commit is made to the code at any stage. The commit operations can only be done by authorized people who have access rights on committing a particular file of the project. Read and Write Access can be file as well as project specific. SVN are pretty common in Unix as well as Windows based machines ( Tortoise SVN ). EDIT : GIT IS WAY MORE COOLER! FORGET ABOUT THIS! 

Windows Presentation Foundation, intially called the Avalon Project, gets a complete picture with the upcoming .NET 4.0 beta, with WPF Toolkit being integrated to it. Missing features like DataGrid or Calender .. etc. are now fully featured in WPF. WPF and Silverlight use the XAML markup language to write UI's which are used in windows as well as web programming. They are highly customizable and have killer 3D support. These UI's adopt the Window OS version capabilities and provide UI's as per what the OS is able to support including the Aero Graphics of Windows Vista and Windows 7. They use Direct X in their back end and are sometimes well suited for Game Development on Windows platform as well. So WPF and Silverlight are the best UI frameworks to work on in windows and web development.
