I think the absorbing into .NET behavior of their standard library is the standout reason to use .NET: You aren't going to have to shim basic functionality out to some random third party who might or might not abandon the code, and could inject malware or telemetry down the road without telling you.

The .NET approach of ensuring you can do nearly everything an app might need basic functionality-wise in the standard library probably sets .NET as one of the most secure platforms to develop with.

It's the anti-NPM, and NPM is terrible for security.
