Hi, looking through some public tenders, I found one [1] from the Council of Europe and their "development kit" says:
The application back-end is built in .NET Core
SQL Server 2019 must be used for development purposes.
from DGA/DIT/DTK(2023)07 [2]
which states
This document presents the Developer's Toolkit, which defines the technical requirements for application development at the Council of Europe's Directorate of Information Technology (DiT).
so we get some insights in the IT environment in this institution (which is seperate from the EU). They use Microsoft's products and the desktop, the servers and the cloud, and applications can only be developed using those tools.
While .NET Core and its compiler and VSCodium ware meanwhile Free Software, the database is proprietary.
