Fiz tudo conforme a documentação, o código apresenta o seguinte erro The request must start with 'JSON' string quando faço um get na url "Calendar/backend".
Como posso resolver este problema?
This is the URL of the backend controller (Calendar/backend) that handles the internal calls made by the client-side library. If you open it directly in the browser, you will receive an error because it expects a POST request with callback details.
If you open Home/Index view it will work fine - that page contains the user interface with the calendar component.
