Waited for almost two years, finally got almost perfect Visual Studio 2008 plug in for FREE!
I tried out AnkhSVN at year 2007 that time still not user friendly enough, thus I use back TortoiseSVN UI.
Now I prefer use AnkhSVN because it is more convenient to make a svn commit
and almost everything inside Visual Studio.
Download AnkhSVN from here
