WCF: Server responding with Bad Request (400)

My WCF client works OK with WCF server except when making a call to the server trying to pass array of custom objects. When the array is 100 items it works fine, but when number of items is 300 the server throws exception Bad Request (400). So I assume that the key to the solution is in configuration files.
First of all here is the app.config for the client. The WCF client resides in a DLL which is Outlook Add-In. I copy this app.config to Outlook.exe.config to Outlook installation dir - something that is required for the Add-In to be loaded by Outlook:

The app.config produces ServerName.exe.config that in bin/Debug (previously I had it as embedded resource but it did not help either...
As you can see I increased all the numbers for buffers, messages, etc. to maximum and made sure that the time values are high enough... I am convinced that that the problem is that somehow either the server or the client do not know about these increased values, but cant figure out why...

Try message encoding with MTOM. See the following links for more info:
http://msdn.microsoft.com/en-us/library/ms733742.aspx
and
http://msdn.microsoft.com/en-us/library/aa395209.aspx
If that doesn't work, use Fiddler to get more information on the error.
A 400-bad request can mean a lot of things.

WCF does not return/show lot of information about what's actually wrong in its side (sad). Try configuring WCF Tracing and see if it helps.

WCF 16384 max array length

Been trying to solve this for a day. I cant seen to find any error with my code, please help. Thank you!
I'm using IIS to host the Service and used add service reference for the client.
I have made sure that I added readerquota and correct binding configuration. Still, the error occur when i'm sending image file with size over 16384kb.

I have figured out the issue, after I updated my server and client to the right values and right binding. My client is still sending default configuration. Also, the configuration.svcinfo file is still in default value and not updated. Any ideas?

Do you change quotas config both server and client side.

First are you sure that you have set your HttpRuntime to be more than 4MB. You can do it as shown below:
<httpRuntime maxRequestLength="1572864"/>
The above element is under system.web element. The .NET framework's http runtime doesnt allow data more than 4MB by default.
Your reader quotas on the server and client are a bit different. Make sure that you have the client reader quotas same as that of the server.
Once you have the above and you still have problems then try enabling Tracing on your service and it should tell you the exact reason why your request is failing. To enable tracing follow the article here

The client should also get a behaviorConfiguration that sets the maxItemsInObjectGraph
<system.serviceModel>
<behaviors>
<endpointBehaviors>
<behavior name="ServiceBehavior">
<dataContractSerializer maxItemsInObjectGraph="2147483647"/>
</behavior>
</endpointBehaviors>
</behaviors>
Then.. reference this new behavior on your client endpoint...
<endpoint address="http://youraddresshere"
binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IService"
contract="" name="" behaviorConfiguration="ServiceBehavior" />
You could also try increasing your maxBytesPerRead="" value in your client and service settings.

How to make TCP enabled on lan

I have written a code for my WPF App to use WCF, wcf is running as Windows service, I want the program wpf to run on client machines. I installed WPF app on PC along with the service and sql server, it is working fine in there. However, when I installed the wpf client on another PC, the client WPF is not able to connect to the server. I mean the WCF windows service is not support for lan usage, however I designed it for this intention only. Could you please check my code and tell me where I have gone wrong please.

Looking forward for the needfull. Thank you.

It appears that all of your service addresses are set to localhost, in both the service and the client config files. Localhost always refers to the machine the program is running on.
You'll need to use the correct machine name for the service and reference it in the client.
For example, say your service is hosted on a machine on the network with the following address - myservicebox:8732. The service's config file would look like this:
<service name="WorkMateWCF.WCFLogin">
<endpoint address="" binding="netTcpBinding" bindingConfiguration=""
contract="WorkMateWCF.IWCFLogin">
<identity>
<dns value="myservicebox" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexTcpBinding" bindingConfiguration=""
contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="net.tcp://myservicbox:8732/WCFLogin" />
</baseAddresses>
</host>
</service>
You would then reference net.tcp://myservicebox:8732/WCFLogin in your client(s) that wish to utilize the service.
Also, note that your service (based on your posted config file) will be using the default values for the specified bindings, which may cause problems for you if you need different values (like bigger message size, etc).
Your client config will use the bindings you've set up as you assign them to the client endpoints via the bindingConfiguration attribute.
Not necessarily a problem in your case (and it looks like you're using the default values on the client anyway, at a quick glance), but something to be aware of.

I later checked the event logs and the issue was with the time on binding and I changed it to 00:10:00 and it seems to work, but this time I landed on a new error and it does not relate to this question.

uploading large xml to WCF REST service -> 400 Bad request

I have been trying to search for this error but no luck so far.
So I have a service on my client with this web.config

and I am uploading the files like this :-
using (Stream stream = new FileStream(strFilePath, FileMode.Open, FileAccess.Read))
{
try
{
using (UploadServiceClient upc = new UploadServiceClient())
{
upc.UploadFile(stream);
}
}
catch (Exception exc)
{
}
}
for small files it works fine, but for large XML files, this failes with 400 Bad Request. What I can do to change these settings to get large XML file to transfer?
Thanks for your help and time

You should to see if the service has the same maxReceivedMessageSize="4194304" as the client and if the XML is indeed smaller than the 4,194,304 byte limit that is set. WCF defaults to a maxReceivedMessageSize of 64K.
UPDATE:
I noticed your config shows the client being configured for basicHttpBinding but the config only shows a wsHttpBinding. The wsHttpBinding config would be ignored by WCF since it doesn't pertain to basicHttpBinding. If the client config file doesn't have a basicHttpBinding element then in .NET 4 a default one is being used. If this is true then you'll run into the 64K limit described above.
