I am attempting to develop an app with only a sign in policy. To the best of my knowledge the supported methods of creating new users for b2c are using the new user dialog on the users page, and with the graph api. Is this correct? Is there a method I'm missing? Which is the preferred method?
When attempting to create users in the new user dialog, usernames become malformed, eg. username@domain.com becomes username_domain.com#EXT#@domain.com
