Study Notes

Purpose of Error Handling in ASP.NET

Ensure application reliability by managing unexpected issues without crashing.
Maintain a seamless user experience by preventing abrupt program terminations.

Automatic Exception Handling Mechanism

ASP.NET provides a built-in feature called "Global.asax" that automatically catches unhandled exceptions.
Utilize the Application_Error event to handle errors globally across the application.

Best Practices for Logging Errors

Implement structured logging to capture detailed error information for troubleshooting.
Store error logs in a secure and accessible location to facilitate easy monitoring and analysis.

Consequences of Unhandled Errors

Unhandled errors can lead to application crashes, resulting in a negative user experience.
Potential exposure of sensitive information through error messages if not properly managed.

User-Friendly Error Message Approach

Use custom error pages to display friendly messages rather than technical details.
Implement the customErrors mode in web.config to direct users to specific error handling pages based on the HTTP status code.
