This depends on which type of certificate file you're providing the
X509Certificate ctor and the framework version you're using (I assume
2.9 since you're using SslStream).
A typical .cer does not have a private key inside it so it wont work.
Using a PKCS#12 file, containing a certificate and a private key, will
The main difference is not the framework but the fact that
Windows CryptoAPI defines relations between certificates and
keys (when persisted) and allow code to "find" a private key
when you supply a certificate (even if its not loaded from a
certificate store). No such facility exists under Linux.

Certainly in what sense ? you tried it ? Google a bit and you'll see
that many people use Mono.Security.dll under Windows - the assembly is
fully managed and will run everywhere.

With the information you provided it looks like configuration issue to
me, not a bug. Try the above (and google the subject) and you should be
ok soon. If not the please fill a bug report with a full sample of what
