In Visual Studio 2008, I can see all my project files in my Solution Explorer, and these files exist in an actual diectory.
However, if I add a file to that directory
I faced the same issue. I added new files and folders but the next time I took latest source code from SVN and then opened the project, it wont show the files which were added.
You can perform the following steps : 1. Solution explorer -> Show all files 2. Those files which are added recently will be displayed without the [@] icon on left side. Right click on the file and Select Include in the project 3. If you see the config file Web (Visual C# Project file (.csproj)) under Web folder, you will see the entries made for these new files. Check in this config file in your svn. 4. The next time you take repo checkout , it wont be an issue as the file details have been added into the configuration.
Hope this helps.
