In my application, all my translation strings are retrieved from webapi as key-value pairs are there any possible way to add them into Resx file at runtime?
You can't add to resx programatically. But you can eg. cache the values to a local file saved on the device and load those on app start or so.
As Junior said that: It's not possible to do that for now. Maybe you can use .json file to update at runtime
