c# - .NET Framework 3.5 and TLS 1.2 -

i have web application uses .net 3.5 framework , wondering if compatible tls 1.2. no in our code dictating tls version. legacy application , recompiling not on table right now. not finding info on whether can or cannot, under impression compatibility more dependent on os version. looks minimum 2008 r2. goal paypal communicate come july 1st.

as can see docs, tls 1.2 not in enumeration sslprotocols, added enum in .net 4.5 (thanks @orhun).

there no workaround tls 1.2 compatibility on .net 3.5.

unfortunately have upgrade .net 4.5 or later tls 1.2 compatibility.
