How change WCF Project Port and NTLM uncheck programatically from another solution?

Hi,

I have a solution which contains 70 projects. In that I want to change WCF project port , NTLM uncheck and connection string  depends on client

and also set startup project programatically. For this am implementing internal site i.e new asp.net project to setting these.

So how to access this solution in my new project?

Can anyone help on this?

Thanks in advance.
