I've just set up a new build server with the Windows 2008 .NET 3.5 SDK, and for some reason it hasn't installed c:\Program Files\Common Files\Microsoft Shared\TextTemplating so I can't run t4 templates on it. I had a look at the install options in add/remove programs and every single option is checked.
Any ideas why it is missing? Any ideas how to get it back?
My understanding is that the T4 engine is a feature of Visual Studio, not the .NET Framework SDK.
I have another build server which does have the T4 stuff on it with just the SDK. I can't remember if I did something special to it or not.
The T4 templating engine comes with Visual Studio 2005 SDK or natively with any installation of Visual Studio 2008. I didn't try the express editions to see if the T4 is present but I strongly recommend that you give it a try.
You can download Visual Studio 2008 Express right here.
