I am using Visual Studio 2017 Pro, and i am being driven crazy by the lack of syntax highlighting for the Jenkinsfile in my project. I am using the Declarative Syntax, but i just cant seem to find anything on getting this to work. My research says that its based on groovy, but i dont see a way to map it to that language either. Any help is appreciated.
This might not be a solution for everyone, but for me, it worked: Jenkinsfiles are the only files without extension I am working with, therefore I opened Tools -> Options -> Text Editor -> File Extensions and then, I checked "Map extensionless files to:" and selected "Javascript Editor"
This does not require to install any extension and the display is great
