Set WCF ClientCredentials in App.config

Question

Is it possible to set clientcredentials for an WCF in App.config?

I would like to avoid doing this:

Using svc As New MyServiceClient
  svc.ClientCredentials.UserName.UserName = "login"
  svc.ClientCredentials.UserName.Password = "pw"

  ...
End Using

Rather the login and password should be part of the configuration.

Answer 1

As far as I know, that is not possible using the serviceModel configuration section due to the security hole it would create. But you could create regular appSettings for these values and use them in code:

svc.ClientCredentials.UserName.UserName = ConfigurationManager.AppSettings("...")

I would advise against this approach though, unless you encrypt the configuration file.

Answer 2

You can try to inherit ClientCredentialsElement (handles default configuration section) and add support for UserName and Password. Than you can register this element in configuration file as behavior extension and use it instead of common configuration section.
