In case you don't happen to know this (maybe you do, maybe you don't)...
There's really no need to use SVN within VisualStudio... it doesn't buy you anything and you can easily use it outside of the IDE. The IDE keeps track of when the files are updated outside of it and will ask you if you'd like to reload the files (when changes are detected, if you happen to use SVN while IDE is open).
TortoiseSVN[
^] has a great interface that makes things easy to do and it's completely independent of the IDE.
