We really love each time we see our Visual T4 products used inside Microsoft.
If you open a .tt file inside Visual Studio, you may notice they look a bit flat – like a wall of black text. We highly highly recommend you download T4 Editor, an add-on to Visual Studio made by Clarius Consulting, to provide you with syntax highlighting and some basic T4 statement completion. They have a free version called the ‘Community Edition’, as well as a much more powerful ‘Professional Edition’ – check out the feature comparison if you are interested. This add-on really makes a big difference in template authoring, as you can see below.
While the bigger font size and strident red-on-yellow colors are ours the ‘highly highly’ is theirs :-)
