Add T4 templates to user script projects




Priority: 6Not yet prioritized for a release


Severity: 3Secondary functionality broken

While editing scripts in MonoDevelop, user has created text templating "T4 Template" file, which was successfully added in file hierarchy in MonoDevelop. Then user switched to Unity editor and switched back to MonoDevelop. Project's solution is always updated with T4 Template files being removed from hierarchy in MonoDevelop.

Reproduced on all versions from 4.2.2f1 to 4.5.0a4;

Repro steps:
1. Create new project in Unity editor;
2. Create new C# script;
3. Open this new file from editor with MonoDevelop;
4. In MonoDevelop create T4 Template file (File -> New -> File -> Text Templating -> T4 template). Name file and tick the box below to add this file to project's "Assets" folder;
5. Observe that T4 template file appears in the solution;
6. Switch to Unity editor, wait while editor finishes script compiling, switch back to MonoDevelop, wait while it refreshes the solution.
7. Observe that T4 Template file has gone from solution hierarchy.


Create T4 templates using the existing MonoDevelop add-in for this once the Monodevelop/Rest Integration is shipped. Also, Unity does not have direct support for handling T4 templates.

To use T4 templates, please use Xamarin Studio or Visual studio in a separate solution (.sln)

    In Unity 5 there is now an option to include tt (or any other) extensions into the C# VS build. Not sure exactly how far back this goes or when it was introduced.

    Can be found under Edit -> Project Setting -> Editor -> C# Project Generation

    I made this code to implement this.

    Should compile that to a dll and place it in a editor folder. Then whenever unity makes the sln it automatically incorporates .tt files if there is a matching generated file with a different extension (which is pretty much given).

    But it would be good to see unity sliver that code into the editor officially. (T4 is great!)

    Use Xamarin Studio or Visual Studio with a separate solution (.sln) to create T4 templates.
