Perhaps it’s just because I’m not familiar with TFS (I’ve worked mostly with SVN), but I don’t understand how to create a branch on a Codeplex hosted project.
I’m using VS2012. In the Source Control Explorer, I select Branching and Merging > Branch… in the context menu, but then I don’t know what to enter in the Target field:

If I try $/wpfanimatedgif/branches/1.3, I get the following error:
The target item $/wpfanimatedgif/branches/1.3 cannot be under the source item $/wpfanimatedgif.
If I try $/branches/1.3, I get this error:
TFS10198: Source control must branch into an existing team project. branches is not a team project.
I also tried to create a new team project from Team Explorer, but I don’t have the required permissions.
So how can I create a branch? Or is it impossible to do it on a Codeplex project?
BTW, the reason I want to create a branch is because I’m working on an experimental feature and I don’t want to publish to the “trunk” (or whatever it’s called in TFS). Perhaps TFS has a different way of handling this scenario? I know about shelving changes, but if I understand correctly, the shelved code won’t be available on Codeplex, will it?
First, it may help to understand what a “Team Project” is – it’s a logical entry in source control at the top-level of the source control tree, and is intended, typically, for a group of developers and various permissions and settings are set at this level. Within a Team Project, you can have multiple development projects such as Visual Studio solutions or Java projects. In this case, your team project is
$/WpfAnimatedGif.As for branching and merging, those occur below the Team Project level, typically as peers to your
trunkormainbranches. Various branching and merging strategies are covered in the TFS Branching and Merging Guide, but a simplified example for a Visual Studio solution called “WpfAnimatedGif” might have a branch strategy that looks like:As for “best practices”, they would be to create a
trunkormainfolder underneath the$/WpfAnimatedGiffolder and move your VS projects beneath that. However, you could create a new folder for each branch and branch each project independently.Eg:
$/WpfAnimatedGif/WpfAnimatedGifbranched to$/WpfAnimatedGif/branches/1.3/WpfAnimatedGifand
$/WpfAnimatedGif/WpfAnimatedGifbranched to$/WpfAnimatedGif/branches/1.3/WpfAnimatedGif.DemoHowever since these branches are independent, you would also have to then merge these two folders independently, instead of atomically from the
branchesfolder.
