问题
A few years ago there was a bug involving ASP.NET and Tortoise/AnkhSvn (can't remember the details), and the solution was to set Tortoise to use "_svn" instead of ".svn" folders for its hidden local files. There's an option for it on the Tortoise settings dialog.
So I still need to do that, or is it not an issue anymore?
回答1:
This feature is controlled by an SVN_ASP_DOT_NET_HACK environnment variable, from which I think it is safe to say that the only reason it existed was to solve the problem with ASP.NET. Now that both VS and ASP.NET itself handle .svn correctly, I don't think there's a compelling reason to use _svn directories.
