If extensions are not yet cached on the system when the net48 tests run, you may experience the following exception:

System.Net.WebException : The request was aborted: Could not create SSL/TLS secure channel.

This seems to be an TLS 1.3 issue with Visual Studio, as per NuGet/NuGetGallery#7705. It can be worked around by running the following commands to force a TLS downgrade:

reg add HKLM\SOFTWARE\Microsoft\.NETFramework\v4.0.30319 /v SystemDefaultTlsVersions /t REG_DWORD /d 1 /f
reg add HKLM\SOFTWARE\WOW6432NODE\Microsoft\.NETFramework\v4.0.30319 /v SystemDefaultTlsVersions /t REG_DWORD /d 1 /f

I've encountered this now running tests from command-line as well. Still unsure of the cause, but its for legacy .NET Framework anyway.
