well what would be cool if TFS could be installed on Linux and use a different database than MSSQL (PostgreSQL, MySQL or MSSQL) (I mean search uses elasticsearch anyway...).
Even better if it would be more close to the online service. And way better if it came with something like gitlab-runner.
Can you clarify what you mean by "more close to the online service"? We update TFS with the bits from VSTS pretty regularly; are you looking for a faster cadence or am I misunderstanding what you're saying?
well some views are looking more clean on the online version. i.e. the project overview page.
currently I'm evaluating git hosting on-premise and another downside is, is that git tfs takes a lot of horse power (this looks unsuitable for a small team)
