Hi,
We have a .net client(desktop) application with 2.0 framework. This application is communicating with SQL Server 2014. We have a requirement to enable the TLS1.2 communication between client and DB server. we have enable TLS 1.2 & TLS1.0 SChanels in DB server machine and enable same in client machine(windows 7 OS). When we run the application It is comuunication with TLS 1.2 by default.
Now we are upgraded the client application frameowrk to 4.0 and test the communication with DB server. While testing i found It is using TLS1.0 to comminicate with SQL server. I did`t made any code chnages just i updated the framework version for the client
application.If i degrade the version to 2.0 it is again communicating with TLS1.2. I tested with 4.7.2 also it is also wrking in the same way. I got some links says it is depends upon the OS not on the .net. (https://stackoverflow.com/questions/38275135/does-net-framework-2-0-support-tls1-1)
Why this bahavour is happen?Please help me on this. Regards,
Kiran
