I am trying to run my service with the WCF Test Client using netTcpBinding (service runs fine with basicHTTP). I am getting the following error
Error: Cannot obtain Metadata from net.tcp://chatmesh/mex If this is a Windows (R) Communication Foundation service to which you have access, please check that you have enabled metadata publishing at the specified address. For help enabling metadata publishing, please refer to the MSDN documentation at http://go.microsoft.com/fwlink/?LinkId=65455.WS-Metadata Exchange Error URI: net.tcp://chatmesh/mex Metadata contains a reference that cannot be resolved: 'net.tcp://chatmesh/mex'. No DNS entries exist for host chatmesh. No such host is known
I don't see anything blatantly wrong that would cause the problem. Below is my app.config. Does anyone have any suggetions for me?

I hosted my WCF Service using Windows Service, but when I call the WCF method I get the following error:
System.ServiceModel.ServerTooBusyException: The HTTP service located
at
http://localhost:8733/Design_Time_Addresses/RahatWcfServiceLibrary/ServerDateTime/
is too busy. ---> System.Net.WebException: The remote server returned
an error: (503) Server Unavailable.
The App.Config in my WCF Service and Windows Service is as follows:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.web>
<compilation debug="true" />
</system.web>

I solved the issue by adding '/mex' at the end of endpoint address in App.Config file in Windows Application that consumes the service.
<endpoint address="http://localhost:8733/Design_Time_Addresses/RahatWcfServiceLibrary/ServerDateTime/mex"
I've been fiddling for two days now, trying to get my TCP endpoint working in my Wcf application.
I've hosted my Wcf app in IIS8 (NOT IIS Express), configured the website to enable net.tcp protocol listening on port 808.
But no matter what I do, I can't reach the TCP endpoint. The HTTP endpoint is working as intended.
Here's my Web.config:
<configuration>
<appSettings>
<add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />

</system.webServer>
</configuration>
I know that the HTTP endpoint doesn't work properly with httpGetEnabled="false", but right now I just need my TCP endpoint to work.
When I try to add a service reference in another project in Visual Studio (in the namespace as my WCF) I write the URL like this:
net.tcp://localhost:808/SimplWCF/WcfService.svc
But I'm not 100% sure this is the correct way of doing it.
Hope somebody can help me.
I finally got it working now!
I removed the relative address in the TCP endpoint, so that my config now looks like this: `
<services>
<service behaviorConfiguration="SimplBehavior" name="SimplWCF.WcfService">
<endpoint address="mextcp" binding="mexTcpBinding" contract="IMetadataExchange"/>
<endpoint address="" binding="netTcpBinding" contract="SimplWCF.IWcfService" bindingConfiguration="DefaultTCPBinding" name="localTcpBinding"/>
<!-- Used for connecting the service to CMS-->
<endpoint address="mexhttp" binding="mexHttpBinding" contract="IMetadataExchange"/>
<endpoint address="public" binding="basicHttpBinding" contract="SimplWCF.IWcfService" bindingConfiguration="DefaultHttpBinding" name="publicHttpBinding"/>
<!-- Used for connecting the webpages to the service-->
<host>
<baseAddresses>
<add baseAddress="http://localhost:50356/SimplWCF/" />
<add baseAddress="net.tcp://localhost:808/SimplWCF/"/>
</baseAddresses>

Thank you for your time!
Following this guide i try to Host WCF service in a Windows Service Using TCP.
this works fine on my computer but when install this service in other computer in the same network got an error: The server has rejected the client credentials
I try to disable Firewall but still same error (and the service running...)
from the client side Add service reference works fine and recognize the service.

192.168.0.100 is the server machine IP address.
Try to use this config for tcp binding:

<security mode="None"></security>
</binding>

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.
I know that this question has been asked many times be other user. But, I have tried all of those approaches to fix this issue. Nothing is working for me. Can you please have a look at my config contents and let me know if I am missing something. Following is my services' config file.

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

I am trying to publish my duplex wcf service on a server with no success, I am able to publish it on local IIS, but when I publish it to server its address become net.tcp://win-rhkt30stjd7/Broadcastor/BroadcasterService.svc. As you would agree such address is not useful at all while creating the service reference on client. I tried to publish it as WCF application project, and service library project but both is giving the same result. Probably something is missing from my Web.config file but I don't know what it is. Please help me out here. Below is my Web.config file:

I dont see any address part in your NET TCP endpoint
1 : Add a base address as below :
<host>
<baseAddresses>
<add baseAddress="net.tcp://localhost:8088" />
</baseAddresses>
</host>
2 : add an address parameter to your net tcp endpoint as :
<endpoint address = "tcpEndPoint"
binding="netTcpBinding"
contract="BroadcastorServiceApp.IBroadcastorService"></endpoint>
3 : Alse give a behavior name as :
<serviceBehaviors>
<behavior name="ServiceBehavior">
<serviceMetadata httpGetEnabled="True" httpsGetEnabled="True" />
<serviceDebug includeExceptionDetailInFaults="True" />
</behavior>
</serviceBehaviors>
And add it to the service like :
<service name="BroadcastorServiceApp.BroadcastorService" behaviorConfiguration="ServiceBehavior">
<endpoint binding="netTcpBinding" contract="BroadcastorServiceApp.IBroadcastorService"></endpoint>
<endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" />
</service>
