Is there a modern and regularly updated tool for generating C# v.7+ classes of XSD? The only tool I know is xsd2code but it is not free and its last update, according to the official site was "Update 4.4 (June 05, 2017)"
There is an alternative tool:
xsd.exe
Run it like this:
xsd /c /namespace:myCompany /language:CS XMLFile.xsd
I have tried it with this XSD, saved it to disk, and runned the tool. It seems to work.
It's available in the VS-20XX command prompt or, in my case in:
C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.7.1 Tools
