I have installed Visual studio 2013 , and I have installed AnkhSvn-2.5.12266.msi for svn, but this "Add-On" is not available in Visual Studio. Why?
It is there. Just change the source control options in visual studio to use Ankh instead of TFS.
Go to Tools/Options/Source Control/Plug-in Selection
, select the AnkhSVN plug-in.
Then restart visual studio and you are good to go. Its working perfectly for me.
Or reinstall the complete ankhsvn client. As this guy here:
