Self-Hosted WCF - Namespace Reservation required? - wcf

I'm running a Self-Hosted WCF Service (SSL).
I've seen that other people use netsh to do a namespace
reservation for their Self-Hosted WCF by doing something like that:
netsh http add urlacl url=https://+:80/MyUri user=DOMAIN\user
My webservice works without that Namespace Reservation. So is there any
reason to do that? Am I missing something? Why would I do that namespace reservation?
MSDN: Configuring HTTP and HTTPS

Because you're running the code as an administrative user. Any restricted user won't be able to host an HTTP server on port 80, or any port for that matter, without having the URL registered to their account.
See Why won't my Windows Service that is hosting a WCF Service run under LocalService or NetworkService accounts, WCF Service Access right: No access rights to this namespace.

wcf hosted in a windows service and httpbindings

I'm working on a wcf hosted inside a windows service. It works like a charm but now I need to reserve a specific hostname for this wcf just as IIS does.
To be more clear, my hosted wcf runs on a windows server machine which response to multiple dns name, but I need to let the wcf reachable only from one of these dns. If I was using IIS it would be achievable by setting a specific hostname within the http-bindings settings, but unfortunately, I can't manage my wcf like that.
To your knowledge, is there any way to reserve a specific hostname for a hosted wcf outside IIS?
Thanks in advance!
yes, you could do it by register the http endpoint at kernel level(http.sys) using the following commands
cmd: ***netsh http add urlacl url=http://fqdn:port/urlpath user=serviceaccount***
Then only on that specific dns/hostname, your http service will listen.

How to set credentials for proxy when connecting to WCF service

how to configure fiddler to monitor wcf calls to a wcf services hosted in IISExpress

situation:
my website (which contains the WCF service) is hosted in IISExpres port number 58366 (http://localhost:58366/myapp)
I have a winforms client which connects to the wcf service using BasicHttpBinding
I want to debug my wcf calls using fiddler, but can't seem find how to redirect wcf calls through fiddler.
IISExpress idiotically binds to the hostname "localhost", not just to the port, so conventional workarounds as with adding a dot to the hostname don't work. Solution seems to be here. Note the last part of the selected answer: Use "localhost.fiddler" and Fiddler will emit "localhost" when proxying.
Rick Strahl has a good article on this here: http://www.west-wind.com/weblog/posts/2009/Jan/14/Monitoring-HTTP-Output-with-Fiddler-in-NET-HTTP-Clients-and-WCF-Proxies
Pretty sure a winforms app will usually pick up the default system proxy as set by fiddler. Are you operating on localhost? Try connecting to your machine name.

I can't access wcf service using net.tcp://<servicename>

I'm using IE8 and can't connect to my WCF service using net.tcp. I'm able to access the same service with http binding just fine. I got two binding enabled in app.config (net.tcp, http). Can anyone tell me if there is a settings that I need to set/play with for viewing service using net.tcp in IE.
You cannot connect to a WCF service using the netTcpBinding through IE.
What you need is a "real" WCF client app, or something like WCF Test Client which is shipped with WCF in the box - just find it and start using it!
Make sure you have a HTTP base address, for your service and a mexTcpBinding endpoint.

How to start/stop windows service from a remote machine through WCF service?

I have created a WCF service which is deployed on my local machine. This service exposes one method which start/stop a windows service on my local machine.
On the remote machine I have created a client that consumes the WCF service. When I try to invoke the method which start/stop service exposed from a WCF service , I get InvalidOperationException . I found that this is the Security issue.
Also when I do the same operation (start/stop windows service) on the local machine it works!!
The WCF service is hosted on IIS 7.0 which is using basichttpBinding. Also Anonnymous access is checked. I have also added <identity Impersonate = true > under the web section in the web config file but still no success.
Please help!!
You set impersonation for ASP.NET. Impersonation in WCF uses its own infrastructure. Moreover in WCF client has to allow service to impersonate his identity. Check this simple example.
