Hi,
I upgrade my MFC app from VC2017 to VC2019, use WINSDK (10.0.19041.0)
Platform : Win10 1903
I had try to connect to server with TLS1.3, but failed.
Use IE 11 (TLS1.3 enabled in advanced setting) failed to , but MS Edge connect OK.
This Win10 1903 version is supported TLS 1.3 using Winhttp??
Any register key need to be added?
