Develop Reference

An existing connection was closed by the remote host with WCF

I have developed WCF windows service using net tcp binding. Its working fine when wcf client and wcf service both are in domain (in two different system)
Getting error when both system are in work group not in domain.
Throwing an exception. Source: System.ServiceModel 4.0.0.0. Exception details: System.ServiceModel.CommunicationException: The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '04:59:59.7955781'. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host
Things I tried:
Turned off Firewalls
Checked port
Increased the timeouts

First, you need to add windows credentials when requesting because nettcpbinding defaults to windows authentication:
ServiceReference1.CalculatorClient calculatorClient = new ServiceReference1.CalculatorClient();
calculatorClient.ClientCredentials.Windows.ClientCredential.UserName = "Administrator";
calculatorClient.ClientCredentials.Windows.ClientCredential.Password = "Password";
If you still have problems after adding credentials, you also need to add a mex endpoint:
<endpoint address="mex"
binding="mexTcpBinding"
contract="IMetadataExchange"></endpoint>
This is my App.config:

My problem is that if I have my website using https:// it fails to make the http call because of CORS. The https website makes an ajax GET request to the localhost.
Now I am trying to change my windows service to https but everywhere I see some command line ssl bindings. Is there a different way I can change my wcf self hosted windows service to use https?
What do I need to do in order to get this http service migrated over to https.
Please provide example of what needs to be modified in my app.config.

I stumbled upon similar problem so what i did was used WCF Configuration tool to write a App.Config for me and inside endpoints I selected mexhttpsbinding and yaa the https binding worked..

Let's just add an https endpoint. The following configuration works properly over both http and https.
<system.serviceModel>
<services>
<service behaviorConfiguration="mybehavior" name="WcfService1.Service1">
<endpoint address="" binding="webHttpBinding" contract="WcfService1.IService1" behaviorConfiguration="webbev"></endpoint>

<endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange"></endpoint>
<host>
<baseAddresses>
<add baseAddress="http://localhost:11010"/>
<add baseAddress="https://localhost:11011"/>
</baseAddresses>
</host>
</service>

Since https protocol is protected by the certificate, we are supposed to bind the certificate to the https port for https endpoint. (we could specify the certificate in IIS binding module instead of CMD if hosting the service in IIS)
netsh http add sslcert ipport=0.0.0.0:11011 certhash=0000000000003ed9cd0c315bbb6dc1c08da5e6 appid={00112233-4455-6677-8899-AABBCCDDEEFF}
Execute CMD with administrator privileges and ensure that the certificate is installed on the local machine certificate store (certlm.msc). Certhash parameter specifies the thumbprint of the certificate. The appid parameter is a GUID that can be used to identify the owning application(located in the project.csproj file)

Feel free to contact me if there is anything I can help with.

Https only works on port 443. so you better have your virtual host created in your SSL script tag in your server configuration.
Or you can also proxy pass your request http:// port(8888) to https:// (port:443)

c# wcf restful self hosted service closes connection / fails after too many requests

I have a self hosted WCF service, that should enable recording of some data that clients send.
(In my case, machines shall report done actions, that the service logs into one xml file for each machine, which is on the file system of the service host.)
For the file access there are global mutexes for each file.
The report method receives a stream, and processes that data until the file writing operations are done.
The problem is, that when I simulate the dataset reporting (1000-2000 reports, each client reports one dataset each 50-100ms, which is not a huge frequency I think) on multiple clients,
my wcf service connection sometimes seems to close (http response 400).
Furthermore the service throws Exceptions
Exception thrown: 'System.ServiceModel.CommunicationException' in System.ServiceModel.dll
Exception thrown: 'System.Net.HttpListenerException' in System.dll
and on the client side some Tasks (one task for each request) are getting canceled
Unhandled Exception: System.Threading.Tasks.TaskcanceledException...
Firstly I thought that the Problem is in the point of file accessing, but now
I think that the problem should be in the WCF Service configuration.
Because I removed the Methods processing (just return true), started 5 clients to 5000 requests at 50ms request frequency and the problem occured.

Problems with Hosting WCF service on IIS (Using WAS) for netTCP bindings?

I created a simple WCF service and hosted it in IIS by creating a new website. In Web.config file,I am providing bindings for http and net tcp.
I created a console client and adding service reference. It generates two binding in client config - for http and for tcp. When I try to invoke the service using tcp, I get this error -
An unhandled exception of type 'System.ServiceModel.EndpointNotFoundException' occurred in mscorlib.dll
Additional information: There was no endpoint listening at net.tcp://computername/Service.svc that could accept the message. This is often caused by an incorrect address or SOAP action.
when I run using Http endpoint , it works fine.
Note -
I am using Windows 10 OS, IIS 10.0 and WPAS\WAS (Windows Process Activation Service) are installed. I already enabled\checked HTTP Activation, TCP Activation in .Net framework in Windows features. And modified IIS server settings to include net tcp. Please check it in attached image.
My website Web.config file looks like
<system.serviceModel>
<bindings>
<netTcpBinding>

WCF Service: The remote server returned an unexpected response: (400) Bad Request

I have a WCF service which works great when small data has to be transferred over the wire. When I increase the data to a bigger size, I get following error:
The remote server returned an unexpected response: (400) Bad Request.

If error is about max reader quota, kindly make the change in web.config under your binding. See if it works.
