I have Windows Service and ASP.NET application. Both the applications are sharing the same .Net Library that is internally using HttpClient class to make GET and POST request.
When Windows Service is making the GET call via shared library, then i dont get any exception. However when ASP.NET make the GET call via the same shared library i am getting the following exception.

Background
We started getting this exception recently in both the applications, so based on research we update the Target framework from 4.5 to 4.6.2 so applications can use TLS1.2 version. After upgrading the target framework windows service is working fine however ASP.NET application is still throws above exception
Does HttpClient use different default System.Net.ServicePointManager.SecurityProtocol in Widows Service vs in ASP.NET
