are there any free Team Foundation Server sites we can use for our private development? Please don't say CodePlex (which I love) because that means the code is all opensource.
Lastly, I also understand that some people might raise the issue of having their private code hosted somewhere by people they do not know, etc.. so please don't raise any security concerns.
I'm guessing there are no free services because of licensing reasons?
Best Solution
Microsoft are currently providing their next generation cloud hosted TFS service at tfs.visualstudiow.com - private repositories are free for up to 5 users but they have indicated that they will be charging for the service when you in the future when you have more than 5 users in your account.
If you are a small start-up and wanted to use TFS inside your firewall, then take a look at the new BizSpark program from Microsoft. This provides basically everything you need to start up a Microsoft technology based company for free (apart from the hardware) - including TFS and Visual Studio.
