Hey Folks,

I have a simple Mono WCF app configured to listen on port 8050. Windows7, no
app.config file, no firewall, no UAC, no antivirus, etc.  When i fire up my
client test application, I get the following error -

InnerException: System.Net.WebException
Message="The underlying connection was closed: Could not establish trust
relationship for the SSL/TLS secure channel." Source="System"
at System.Net.HttpWebRequest.GetResponse() at
            Message="The remote certificate is invalid according to the
validation procedure."

I went through the following steps (exactly) to generate a self signed test
root and server cert using the mono cert store and related mono cert tools. 
I also use the mono httpcfg to assign the cert to the port.  Am I missing

makecert -r -n "CN=My Own Test CA" -sv root.key root.cer

certmgr --add -c -m Trust root.cer

makecert -iv root.key -ic root.cer -eku -n
"CN=mymachine01" -sv mymachine01.pvk mymachine01.cer

certmgr --add -c -m My mymachine01.cer

httpcfg -add -port 8050 -pvk mymachine01.pvk -cert mymachine01.cer
