Why does the .net SSLStream not show TLS in Wireshark?

Why does the .net SSLStream not show TLS in Wireshark?

So, I was curious about how the traffic through a .net SSLStream would
look like and I set up a small client/server application you can find
here.
It establishes a TLSv1 connection between the two hosts, with the
following parameters:
Cipher: Aes128 strength 128
Hash: Sha1 strength 160
Key exchange: RsaKeyX strength 2048
Protocol: Tls
Is authenticated: True as server? True
IsSigned: True
Is Encrypted: True
So I expected to see some TLSv1 in my wireshark traces between the two
hosts, but there was not a single one.. I had some SSL and TLSv1.2 in the
protocol-field, between my computer and some other hosts, but not between
the hosts communicating through the .net SSLStream

Is this how it is supposed to look?
I expected something like this: (found on google)..
