VisualSVN is a plugin for Microsoft Visual Studio for seamless integration with Subversion.
Be up to date without hassle
With VisualSVN you are one click away from reviewing your changes, committing them and getting other's changes. Don't worry about modification of solution or project files - VisualSVN will reload them when necessary.
Move things around safely
When you need to rename or move class, file, folder or project - just do it. VisualSVN cares about the rest - you will not corrupt your working copy accidentally and the history of changes will be correctly reflected in your repository.
