I have just a very basic WCF service implemented and I want the clients to have some properties in their config automatically generated, like maxReceivedMessageSize, maxBufferSize, etc (the default maxReceivedMessageSize is not enough for me). I have the below config in service application's web.config file. I have the properly configured binding (BasicHttpBinding_IService1_YY), that binding is referenced in both service endpoint and client endpoint (I am not sure there is need for client endpoint as well). I also have mexHttpBinding typed endpoint under service. The service points to a behaviour where httpGetEnabled is true.
After all, when I generate the client from this the binding parameters won't be there, it will use the default values. Naturally the wsdl doesn't contain those parameters.
So my question would be is this something that is out of WCF's scope? Do I have to manually maintenance the client config from this perspective if something change? Is there any solution for this issue, because I went through many stackoverflow and other topics and found nothing or I was careless.

And the generated client config:

<basicHttpBinding>
<binding name="BasicHttpBinding_IService1_YY" sendTimeout="00:05:00" />

bindingConfiguration="BasicHttpBinding_IService1_YY" contract="IService1"
name="BasicHttpBinding_IService1_YY" />
</client>
</system.serviceModel>
</configuration>
Ok, the name of the binding really appears correctly, but nothing more. When I manually adjust it, then everything works ok, but I think there should be a more suitable solution.
Can you please help me out at this one? Thanks in advance.
The answer is probably: Yes.
The feature of WCF is that the client and server can evolve separately. The server settings are not automatically updated to the client, you need to manually set the parameters you need on the client.
You may try using the "update service reference" feature to update instead of creating a new service reference.

I have created a IDummyService contract implemented by DummyService. I am trying to self-host this service using the following configuration:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />
</startup>
<system.serviceModel>
<services>
<service name="DummyService.DummyService" behaviorConfiguration="MEX">
<host>
<baseAddresses>
<add baseAddress="http://localhost:8733/" />
</baseAddresses>
</host>
<endpoint address="DummyService"
binding="basicHttpBinding"
contract="DummyService.IDummyService"/>
<endpoint address="net.tcp://localhost:8734/DummyService/"
binding="netTcpBinding"
bindingConfiguration = "TransactionalTCP"
contract="DummyService.IDummyService"/>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
</services>
<bindings>
<netTcpBinding>
<binding name = "TransactionalTCP" transactionFlow = "true"/>
</netTcpBinding>
</bindings>
<behaviors>
<serviceBehaviors>
<behavior name = "MEX">
<serviceMetadata/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>
The Service Host code that runs fine and starts these endpoints. However, when I try to access the following endpoints I get error as Page isn't working in Chrome browser.
http://localhost:8733/DummyService/
http://localhost:8733/mex/
However, I can access the page http://localhost:8733/
I don't understand why is that.
I thought the endpoint address is address entry for that endpoint appended to host's baseaddress
Any ideas what I am doing wrong ?
Thanks.
You have applied the attribute behaviorConfiguration="MEX" but didnt make use of it,you need to enable the metadata discovery which is false by default in WCF for security reasons.
<serviceBehaviors>
<behavior name = "MEX">
<serviceMetadata httpGetEnabled="true"/>
</behavior>
</serviceBehaviors>
Now when you browse the http://localhost:8733/DummyService/ and http://localhost:8733/mex/ ,a blank page will be displayed in the browser,instead of default error page.
And also if you want to test the net.tcp endpoint you can use WCFtestclient.exe.

This is just a sample of my web.config file. When I run the service in the local host it runs fine and with the help of wcf test client I am getting the required output.
But when I put the dlls & web.config in the server where I have to host the service it's throwing an error
"Could not find a base address that matches scheme HTTP for the endpoint with binding BasicHttpBinding. Registered base address schemes are [https]"
Could any one tell me what the reason for the above error is?
General Flow of my web service
Application -> Server hosting(calc.svc) -> https://******.****-*/*****_*****?SOAP(authenticated)
when i add the service reference app.config got generated and by default basichttpbinding got added to app.config file.
As per my understanding web.config file is used to host the service in iis & i think my web.config is wrong.
In the client end point what should be the end point to calc.svc or https://*?soap?
Is the basichttpbinding ok for the https://prd36/calc.svc url?
do i need to specify one more binding for the application too?
Please help me understand i am heavily confused as the web.config which i have edited is a existing one which is still running the old service reference.
<serviceMetadata httpsGetEnabled="true"/>
<endpoint address="json" binding="webHttpBinding" contract="Contract.IService" behaviorConfiguration="web"></endpoint>
<endpoint address="mex" binding="mexHttpsinding" contract="IMetadataExchange"/>
above changes i did and the service url is running in web browser.
Use http:// instead of https:// in your endpoint address.
OR
User BasicHttpsBinding instead of BasicHttpBinding in your endpoint.
follow this link if the problem still exist.

I want my clients be able to access the service through the following links, but the links don't work: (or may be my syntax is wrong for the links below, let me know if that is the case)
https://myservice/service.svc/ClientA
https://myservice/service.svc/ClientB
https://myservice/service.svc/ClientC
following links work, but i don't think this is due to my configuration, as if i write anything after the last forward slash it still works ....
https://myservice/service.svc?wsdl/ClientA
https://myservice/service.svc?wsdl/ClientB
https://myservice/service.svc?wsdl/ClientC
https://myservice/service.svc?wsdl/asfgvafgfgf ... (this works too !!!)
Please let me know how to achieve this. I don't want to create separate service for all clients.
if this works, i want to use different contract="MyService.IService" in the endpoint definition for all clients, as the methods for each clients exposed in service would differ.
i also want to ask, would i be able to specify which connection string to use, depending on via which endpoint client is accessing the service?
And lastly: I Dont want:
https://myservice/service.svc
https://myservice/service.svc?wsdl
links to be accessible, i want the clients to use only their specified links ...
is that at all possible, or should i create separate services for each client ... ?
Thanks.
I think it require some setting in config file.

THis might help you.
I get this:
An error occurred while receiving the HTTP response to http://localhost:8732/Design_Time_Addresses/PersistencyService/Service1/. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.
Why do I get this? I assume it is because the method takes about 1 min to complete. How can disable any time limit?
I get this when running in VS a Windows form project that uses a WCF service in the same solution

The exception message is An existing connection was forcibly closed by the remote host.
I must also add that I get about 70MB of data from the service
On the client side, you need to add some settings to your app.config:
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="LongRunning" sendTimeout="00:10:00" />
</wsHttpBinding>
</bindings>
<client>
<endpoint name="Default"
address="....."
binding="wsHttpBinding"
bindingConfiguration="LongRunning"
contract="IYourServiceContract" />
</client>
</system.serviceModel>
You didn't give us much to go on - no config, nothing.... so I'm left just guessing what settings you might have.
Basically, you need to define a binding configuration for the type of binding you're using, and you need to increase the sendTimeout attribute on that binding configuration (here in my sample: 10 minutes). You cannot completely turn off the timeout - you can increase it, but not turn it off.
Then, your client side config must make a reference to that binding configuration you've defined, by specifying a bindingConfiguration="...." attribute on the <endpoint> configuration, and using the same name for the binding configuration as when you defined it.
Maybe this is enough - but maybe, you'll also need to increase some of the timeouts on the server side. Try this first - if it doesn't work, come back and ask again - and please, next time: provide us with some more useful info, like your code and config!
When I pass a list of objects out of my silverlight app using WCF everything works fine until the List grows too big. It seems that when I exceed 80 items I get the error:
The remote server returned an unexpected response: (404) Not Found
I'm presuming that it's because the List has grown too big as when the List had 70 items everyhing works fine. Strange error message though, right?
In the config file I change the maxBufferSize to the highest value that it will accept but still I can't have more then 80 items in my List.
How can I pass out large objects without having to split the object up?
Thanks Shawn, so where exactly do I do it?
This is my ServiceReferences.ClientConfig

and this is the server config that you mentioned

If you are sending out a large number of items from WCF, also make sure that maxItemsInObjectGraph is a relatively high number
<behaviors>
<serviceBehaviors>
<behavior name="YourBahvior">
<dataContractSerializer maxItemsInObjectGraph="6553600"/>
</behavior>
</serviceBehaviors>
</behaviors>
There are two config files. The silverlight clientconfig will let you send the larger message, but if you'r eusing WCF, there is a server web.config that limits the size of the received message (to prevent DDOS attacks).
In server side, change the config file to make the service can accept large message.
Add a basicHttpBinding configuration in <system.serviceModel> section:
<?xml version="1.0" encoding="utf-8" ?>

<readerQuotas maxStringContentLength="300000000"/>
</binding>
</basicHttpBinding>
</bindings>
.......
Add the configuration to the service binding.
<endpoint address="" binding="basicHttpBinding" bindingConfiguration="MyBasicHttpBinding" contract="WcfService1.IService1">
