Update: CodeSmith Generator 6.5 features a standalone editor. You can access it through the start menu shortcut.
We have heard a lot of feedback that you guys love the new integrated editor inside of Visual Studio, but we have also heard from a lot of people that they want the stand alone editor as well. So we just wanted to let you guys know that we have begun working on the new stand alone template editor. Luckily with the way that we have designed the integrated editor, it shouldn’t be a huge project. Hopefully we will have something to show in a couple of weeks.
Thanks for your feedback and keep it coming!
