How can I handle global exceptions in ASP.NET MVC?

You can handle global exceptions in ASP.NET MVC by using the Application_Error method in the Global.asax file.

Can you show me an example of how to implement that?

Sure! In the Application_Error method, you can log the error and redirect to a custom error page. Here's a sample code:

protected void Application_Error(object sender, EventArgs e)
{
    Exception exception = Server.GetLastError();
    // Log the exception
    // Redirect to error page
    Response.Redirect("/Error");
}

What if I want to use a custom error handling middleware?

You can create a custom middleware by implementing the IMiddleware interface and handling exceptions there. This allows for more flexibility.

Is there a way to return JSON responses for API errors?

Yes, you can return JSON responses by checking the request type and formatting the response accordingly in your middleware.
