Get Visual Studio to run a T4 Template on every build

Question

How do I get a T4 template to generate its output on every build? As it is now, it only regenerates it when I make a change to the template.

In Visual Studio 2017 (probably next versions too), you should add this in Pre-build event:

"$(DevEnvDir)TextTransform.exe" -out "$(ProjectDir)YourTemplate.cs" "$(ProjectDir)YourTemplate.tt"

p.s. Change path to your template if it's located not in root project directory.
