I have tried it with Visual Studio 2012 RC and it works really good. There is just one problem. Windows 8 Metro applications is not supported by the continuous build. I got strange errors like “’ValidateAppxManifest failed. Retrieving the COM class factory for component with CLSID {…} failed”.
After talking with Microsoft about it, I found out that they are running the service on Windows 2008 R2 servers, which is understandable, and thus Windows 8 apps can not be built. What is not understandable is that they do not have any plans or dates when Windows 8 apps will be supported! To speed things along, I have added a request for Windows 8 support on the Visual Studio user voice site (http://visualstudio.uservoice.com/forums/121579-visual-studio/suggestions/2970091-support-windows-8-apps-in-tfspreview-hosted-build). Please, my reader, go to the site and vote for this. If we get enough votes Microsoft will implement it.
Microsoft’s proposed solution for now, is to set up our own on-premise build machine that connects to the cloud service. This is no big deal, but it would have been really sweet if you could have everything in the could.
