Windows.Web.Http Authentication with a blank username / only password

Question

I'm new to developing Windows 10 Universal Apps. I need to authenticate with Windows.Web.Http with a blank/empty username and only with a password. If I use a empty string or null I've got an exception on creating the credentials.

Any idea?

Ok, i've got it by myself:

First I tried using (empty username throws Invalid Argument exception):

filter.ServerCredential = new Windows.Security.Credentials.PasswordCredential(uri.ToString(), username, pass);

Now I am using:

var buffer = Windows.Security.Cryptography.CryptographicBuffer.ConvertStringToBinary(username + ":" + pass, Windows.Security.Cryptography.BinaryStringEncoding.Utf8);
