WCF Error: Metadata publishing for this service is currently disabled - asp.net

Question

I want to publish a Webservice with basicHttpBinding configuration. I am using a basicHttpBinding configuration to increase the default message size of 65536 bytes. The problem I am having is that when I use the web.config settings as shown below, I am getting an error:
Metadata publishing for this service is currently disabled.
My Main goal is to be able to increase the default message size and able to save binary file in database, therefore any other config is welcome, however I was trying to keep it as simple as possible to avoid further issues.
Can you please spot what is wrong with my configuration?
Service.config code is below..

Put this configuration in your web.config.
