I found this configuration to extend connetionlimit in .NET

I need to know that what are appropriated for? Windows Application/Web 
Services/Web Applications?

Caused by I have problem when I have process of TCP Client in Web Services 
and when I stress, there are some limitations of connection (I thought 16 
connections max)

If I need to extend, how can I config?

<configuration>
  <microsoft.web.services3>
    <messaging>
      <transports>
        <add scheme="soap.tcp">
          <connectionLimit
            inbound="-1"
            outbound="-1"/>
        </add>
      </transports>
    </messaging>
  </microsoft.web.services3>
</configuration>
