I have registered my bot in Microsoft Bot Framework. When I talk to Bot from the Microsoft page, it asks me confirmation questions in Spanish. Now I add the Facebook channel. When I start a conversation in Facebook Messenger, it asks me confirmation questions in English.
So, How I set a different language to Bot Framework in Facebook Channel in .NET?
In .NET you can set the locale of the activity with
activity.Locale = "es-ES";
In the Post method of the controller. (In Controllers/MessagesController.cs for example)
