Handling exception in asp.net core?

Question

I have asp.net core application. The implementation of configure method redirects the user to \"Error\" page when there is an exception ( in non Development environment)

You should write your own middleware to handle custom exception handling. And make sure you add it towards the beginning (first if possible) of your middleware stack because exceptions that happen in middleware that is "earlier" in a stack will not be handled.

Example:

public class CustomExceptionMiddleware
{
    private readonly RequestDelegate _next;

    public CustomExceptionMiddleware(RequestDelegate next)
    {
        _next = next;
    }

    public async Task Invoke(HttpContext context)
    {
        try 
        {
            await _next.Invoke(context);
        } 
        catch (Exception e) 
        {
            // Handle exception
        }
    }
}
