Is there a way to pass a specific UI language to the registration page? This is coming from the website and I want it to be the defaut option.
you can send the culture with these headers
c=...
uic=...
and for MVC use culture parameter like below
/register?culture=tr
must be the first parameter of the query string
and last option; you can always override AbpUserRequestCultureProvider
UPDATE:
According to the implementation it accepts query string parameters as culture like below
?culture=es-MX&ui-culture=es-MX
