Fiddler and TLS 1.2 support

After all the issues we have seen in the last year with SSL/TLS a lot of web applications have already disabled SSL entirely and started using TLS 1.2.
Therefore I want give an update on my Fiddler post:
http://secattic.blogspot.com/2012/10/1-2-3-see-what-is-in-saml-response.html
Fiddler2 cannot handle TLS 1.2 traffic, so you should upgrade to Fiddler4.
In short Fiddler4 is using the .Net Framework 4 which can handle TLS 1.2 traffic while framework 2.0 cannot.

see also, just select the different framwork versions and see yourself.
