Doing some research on the current state of mono, collecting the findings:
- Current stable is 3.10.0.
- Xamarin’s Linux packages are currently at mono 3.10, and monodevelop 5.5.
- T4 templates are “supported” by MonoDevelop, but build-time refreshing is not. There is a separate tool that can be used to evaluate T4 templates under mono(develop). This requires listing all .tt files, maybe viable via custom msbuild fragment.
