Hi Werner! VisualSVN works properly when all files included in the solution have a common file system folder named working copy root. In you case when you add project Utility to the "Test" solution VisualSVN continues to use Test folder as a working copy root. So Utility is not considered to be under Subversion.
There are two solutions: 1. You can try to setup working copy root manually using VisualSVN -> "Set Working Copy Root.." command (so that both Utility and Test folders are under the root folder). 2. You can make a "reference" from the solution "Test" to the solution "Utility" using svn:externals. It is a recommended way. Here is the detailed description of svn:externals: http://www.visualsvn.com/support/svnbook/advanced/externals/. Hope this helps! -- Regards, Olga Dolidze VisualSVN Support
