Problem:
While uploading a file by converting file content into array of bytes and sending it to server side via WCF, generates following exception.

The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://tempuri.org/:***. The InnerException message was ‘There was an error deserializing the object of type ****. The maximum array length quota (16384) has been exceeded while reading XML data

Impact:
You will not be able to download or upload file bigger than 1 megabyte.

Solution:
Change the web.config or the app.config file to the following settings.

<bindings>
        <basicHttpBinding>
          <binding
                   maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" closeTimeout="0:50:0" openTimeout="0:50:0" receiveTimeout="0:50:0" sendTimeout="0:50:0"
                   >
            <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="2097152"  maxBytesPerRead="4096" maxNameTableCharCount="16384" />
          </binding>

          </basicHttpBinding>

</bindings>

After this recompile the file and run you application again
