Status code 413 (RequestEntityTooLarge): Request Entity Too Large. WCF Programmatically

[Mohamed Thaufeeq]

I am calling a WCF web service programmatically by generating class files through [`SvcUtil.exe`][1].

All working fine but when I try to send an image (literally a file with size more than 200KB), I get this error.

I know I need to increase `maxReceivedMessageSize` and `maxBufferPoolSize` to the maximum to send large files to the WCF service. Hence, the XML version of doing this will be like below:

<binding name="SampleBinding" allowCookies="true" messageEncoding="Mtom" maxReceivedMessageSize="20000000" maxBufferSize="20000000" maxBufferPoolSize="20000000">
<readerQuotas maxDepth="32" maxArrayLength="200000000" maxStringContentLength="200000000"/>
<security mode="None">
<transport proxyCredentialType="Basic"/>
</security>
</binding>

In this app, since I am using class files generated by SvcUtil, I need to call my WCF service method programmatically.

So I did,

var binding = new BasicHttpBinding();
binding.MaxReceivedMessageSize = binding.MaxBufferPoolSize = long.MaxValue;
binding.AllowCookies = true;
binding.ReaderQuotas = new System.Xml.XmlDictionaryReaderQuotas();
binding.ReaderQuotas.MaxArrayLength = binding.ReaderQuotas.MaxBytesPerRead = int.MaxValue;
binding.ReaderQuotas.MaxStringContentLength = binding.ReaderQuotas.MaxNameTableCharCount = int.MaxValue;
binding.ReaderQuotas.MaxDepth = int.MaxValue;

webAPI = new WebAPIClient(binding, new EndpointAddress(soapUrl));

The XML version works really well but the C# version failed with below stack trace:

I don't know what's wrong. May you help me?
