My recommendations for clean, short paths are as follows:
- Pick a folder that's going to contain your solution folder, like "Source." After following this step, you will end up with a folder in Source called Org.Grp.Team.Project: Get the full path to Source, do a File > New > Project, and create an empty solution (under Other Project Types > Visual Studio Solutions) in Source. Check both the Create Directory For Solution and Add to Source Control boxes and click OK. This will open the solution in Solution Explorer.
- To add a project to the solution and to source control, right click on the solution and do an Add > New Project. Here's where some knowledge about how Visual Studio behaves is helpful: the value you enter for Name will be the name of the folder that's created. We don't want to name it Org.Grp.Team.Project.Assembly, because that introduces a lot of redundancy and makes our paths too long. The name you want here is just the "Assembly" part. Click OK and you'll get the new project in the solution. The name next to the project entry in the Solution Explorer tree only represents the name of the project file, not the name of the assembly. To properly name your assembly, go to the project properties and change the value for Assembly Name (I also recommend changing Default Namespace) to Org.Grp.Team.Project.Assembly or whatever you like.
If you need to change a folder name later, you don't need to worry about the project file in that folder, but you will need to fix project references that point to that project, as well as solution files for solutions that contain that project.
My last tip is that it's sometimes a good idea to copy the directory mapped to the project root to a temporary backup, wipe out the original, and do a full force get from TFS. This will eliminate any garbge folders and files that have accumulated on your machine when doing things like renames or removing projects or files you decided you didn't want from a solution - the backup is just in case some of those folders or files aren't garbage, like important stuff that didn't get checked in for some reason.
