WCF Service Reference Support Files Not Updating

问题

I have a VS 2010 solution containing a WCF service project and a unit test project. The unit test project has a service reference to the WCF service.

Web.config for the WCF service project sets a number of binding attributes to other-than-default values:

web.config: (Specifically note maxBufferSize="20000000")

<basicHttpBinding>
    <binding name="basicHttpBindingConfig" maxReceivedMessageSize="20000000" maxBufferSize="20000000" maxBufferPoolSize="20000000">
      <readerQuotas maxDepth="32" maxArrayLength="200000000" maxStringContentLength="200000000"/>
      <security mode="TransportCredentialOnly">
        <transport clientCredentialType="Ntlm"/>
      </security>
    </binding>
</basicHttpBinding>

While examining this issue, I came to realize that the unit test project's service reference support files do not contain the values I would expect (i.e. the values configured in the WCF service's web.config):

configuration.svcinfo: (Specifically note maxBufferSize="65536")

  <binding hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" messageEncoding="Text" name="BasicHttpBinding_IBishopService" textEncoding="utf-8" transferMode="Buffered">
    <readerQuotas maxArrayLength="16384" maxBytesPerRead="4096" maxDepth="32" maxNameTableCharCount="16384" maxStringContentLength="8192" />
    <security mode="None">
      <message algorithmSuite="Default" clientCredentialType="UserName" />
      <transport clientCredentialType="None" proxyCredentialType="None" realm="" />
    </security>
  </binding>

Deleting and re-creating the service reference or updating the service reference re-creates the files, but I still end up with the same values.

Why?

Update

Here's the app.config of the client

<binding name="BasicHttpBinding_IMyService" closeTimeout="00:01:00"
                    openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
                    allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
                    maxBufferSize="200000000" maxBufferPoolSize="200000000" maxReceivedMessageSize="200000000"
                    messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
                    useDefaultWebProxy="true">
                    <readerQuotas maxDepth="32" maxStringContentLength="200000000" maxArrayLength="200000000"
                        maxBytesPerRead="200000000" maxNameTableCharCount="200000000" />
                    <security mode="None">
                        <transport clientCredentialType="None" proxyCredentialType="None"
                            realm="" />
                        <message clientCredentialType="UserName" algorithmSuite="Default" />
                    </security>
                </binding>

Same issue here and no solution after half a day messing about with config files... Changing automatically generated files is usually frowned upon, so my feeling says that "there has got to be a better way, Dennis".

UPDATE: I got my problem fixed by removing the name attribute in the binding configuration. So your current web.config is looking like this

<basicHttpBinding>
  <binding name="basicHttpBindingConfig" maxReceivedMessageSize="20000000" maxBufferSize="20000000" maxBufferPoolSize="20000000">
    <readerQuotas maxDepth="32" maxArrayLength="200000000" maxStringContentLength="200000000"/>
    <security mode="TransportCredentialOnly">
      <transport clientCredentialType="Ntlm"/>
    </security>
  </binding>
</basicHttpBinding>

would become

<basicHttpBinding>
  <binding maxReceivedMessageSize="20000000" maxBufferSize="20000000" maxBufferPoolSize="20000000">
    <readerQuotas maxDepth="32" maxArrayLength="200000000" maxStringContentLength="200000000"/>
    <security mode="TransportCredentialOnly">
      <transport clientCredentialType="Ntlm"/>
    </security>
  </binding>
</basicHttpBinding>

I think you only need to this at the client-side. By removing the name attribute, you essentially change the default basicHttpBinding configuration for your app, as far as I understand it. Credits for this solution here.

Another update: if you name your service configuration correctly (including the namespace) it will pick up the binding configuration. So instead of

<service name="ServiceName">

you need

<service name="My.Namespace.ServiceName">

回答2:

That is correct behavior. Some information included in binding are specific to only one side of the configuration and both client and server can use completely different values. Also these values are defence against Denial of Service attach so service doesn't want to show them publicly.

Those values affects only processing of incoming messages so service configures how it will handle incoming requests and client configures how it will handle incoming responses. Requests and responses can have different characteristics and different configuration. There is no need for service to be configured to accept 1MB requests if it always receives only few KB requests and returns 1MB responses.

Btw. this is WCF specific feature not related to general web services and because of that there is no standardized way to describe this in WSDL.
