Named pipe wrapper, usage over network

I have an working implementation of how two form applications and use named-pipe-wrapper v1.5.
Connection like this on server:
server = new NamedPipeServer<string>("named_pipe_test_server");
Connection like this on client:
client = new NamedPipeClient<string>("named_pipe_test_server");
now i have my server on another computer, same network.
how do i adress this.
I want to type like,
client = new NamedPipeClient<string>("//192.168.100.2//named_pipe_test_server");
is this possible ? in this case, what is the syntax ?

You can use the NamedPipeClientStream(String, String) overload to specify the name of the remote computer.
client = new NamedPipeClientStream("192.168.100.2", "named_pipe_test_server");

In named-pipe-server you can specify the server name as the second parameter to NamedPipeClient.
private readonly NamedPipeClient<string> _client
= new NamedPipeClient<string>(Constants.PIPE_NAME,"SPAN24");
You must use the Computer name not it's IP address.
You need to get the source from Github.

The second parameter is not available in the Nuget package.

Exchange Web Services Autodiscover non default link

I am writing a piece of software that runs on a utility device on a customers network, but not on the domain. The autodiscover service is not available off domain the same as it is either on the domain or even on the internet. None of the ways the service works by default will find it according to the docs, but the customer's IT staff tells me, supposedly :/ , it will all work if I can access Autodiscover at the link they gave me. Is there any way to override the default approach and pass it this url to autodiscover from? Hardcoding the link to /exchange.asmx is not an option nor is adding this device to the domain.
I am reusing, and now tweaking, a tried and true piece of software that has been deployed many times, but this situation is a first.

Using the EWS Managed API you may be able to do it using the AutodiscoverService class. It has a constructor that takes the URI of the Autodiscover service as a parameter.
Your code should look something like this. Note that I disable SCP lookup as you are not on a domain. I have not actually tried this code but give it a try:
AutodiscoverService ads = new AutodiscoverService(new Uri("..."));
ads.EnableScpLookup = false;
ads.Credentials = new NetworkCredential(...);
ads.RedirectionUrlValidationCallback = delegate { return true; };
GetUserSettingsResponse grResp = ads.GetUserSettings("someemail#domain.com", UserSettingName.ExternalEwsUrl);
Uri casURI = new Uri(grResp.Settings[UserSettingName.ExternalEwsUrl].ToString());
var service = new ExchangeService()
{
Url = casURI,
Credentials = ads.Credentials,
};

UriBuilder points to localhost instead of domain name

My site has a public section that is accessed by http and a https part to requires logging in. When logging out of the site, it redirects to the http public index page.
Previously I had done this with stating the full url to point too. Recently I had to get rid of such things so the site can be run on numerous domains, for testing.
I tried using UriBuilder to convert https links to http link so that a website no longer has to use direct pointing to a specific url. This should allow the site to use any domain name. Right now it points to the computer name.
if (Request.IsSecureConnection)
{
UriBuilder ub = new UriBuilder();
ub.Path = "/html/index.html";
ub.Scheme = Uri.UriSchemeHttp;
ub.Port = -1; // use default port for scheme
Response.Redirect(ub.Uri.ToString(), true);
//An old direct link to the site
//Response.Redirect("http://www.someaddress.com/html/index.html");
}
When the code is triggered remotely on the test server instead of pointing to the right domain it returns me to the address
http://localhost/html/index.html
Instead of
http://testserver/html/index.html
I have no idea why it is doing this instead of returning the address I am connecting to the server via.

If you don't specify host than default host ("localhost") will be used - see UriBuilder() constructor article on MSDN.
Fix: specify host (probably based on incoming request's host).
ub.Host = GetMeIncomingHost();

Because in the URI to which you are redirecting, you haven't specified an authority (host). Thus, your redirect sends a 302 Found HTTP status and the response contains a location: header that looks like something like this:
location: /html/index.html
That is a relative URI, relative to the current URI from which the redirected request originated. That means it inherited the scheme and authority component of the requesting page (which, obviously, in your case, was an http://localhost:xx/....
To fix this, seed your UriBuilder in its constructor with HttpContext.Current.Request.Url. That should about do it:
UriBuilder ub = new UriBuilder( HttpContext.Current.Request.Url );
ub.Path = "/html/index.html";
Response.Redirect(ub.Uri.ToString(), true);

Dynamically switch WCF Web Service Reference URL path through config file

How do you dynamically switch WCF Web Service Reference URL path through config file ?

Are you just wanting to override the URL that is in the config to a different url. Say you have a test service and a live service. You can just do this.
client.Endpoint.Address = new EndpointAddress(Server.IsLiveServer() ?
#"LiveUrl" : #"TestURl");
Where those url come from wherever you want

Just to expand on the answer from Erin: -
MyClient client = new MyService.MyClient();
client.Endpoint.Address = new EndpointAddress(new Uri("insert new url here"),
client.Endpoint.Address.Identity, client.Endpoint.Address.Headers);
client.Open();
HTH!

There is no dynamic switching. Each time you want to use another URL you must create new instance of service proxy (client) and pass EndpointAddress or enpoint configuration name to the constructor.

I have been trying to do the same thing but most of the accepted answers in various posts just change the address. Currently under .net 4.7, simply changing the address itself does not work. If you have two different servers and wanting it to switch from one to the other, you have to do this:
var client = new MyService.Service1Client();
var newAdrEndpoint = new EndpointAddress(new Uri("second server address"));
client = new MyService.Service1Client(client.Endpoint.Binding, newAdrEndpoint);
Essentially you need to create a new service using the same binding from the first server and passing in the new address. This is the simplest method I have found.

sure you can do this, have a look here: How to config clients for a wcf service?
it is absolutely normal to point to localhost in development and to change the address (url) in production in the web.config

you can´t chance endpoint url after any calling.
E.G.
in that case, you will get answer from NEWURL:
MyClient client = new MyService.MyClient();
client.Endpoint.Address = new EndpointAddress("NEWURL");
client.Hello(); //return is hello response from NEWURL
but if you will call any method before changing url, the url will be used from app.config, like next example:
MyClient client = new MyService.MyClient();
client.Endpoint.Address = new EndpointAddress("NEWURL");
client.Hello(); //return is hello response from BASEURL

C#: Get IP Address from Domain Name?

How can I get an IP address, given a domain name?
For example: www.test.com

You can use the System.Net.Dns class:
Dns.GetHostAddresses("www.test.com");

You could use the GetHostAddresses method:
var address = Dns.GetHostAddresses("www.test.com")[0];

You can get the same results by using:
Dns.GetHostAddresses("yahoo.com");
or
await Dns.GetHostAddressesAsync("yahoo.com");

My answer could be more the same above answers, but here i get the current web app hosted URL / domain name using code and obtained the IP address and from that. I used the code in my C# MVC Web app and its working fine.
Uri myUri = new Uri(((System.Web.HttpContextWrapper)HttpContext).Request.Url.ToString());
var ipAddress = Dns.GetHostAddresses(myUri.Host).FirstOrDefault().ToString();
