Common Errors In Asp Net Mvc
Client-side errors happen in the user’s browser. They are often due to wrong inputs or broken scripts. Common examples include form validation errors and JavaScript issues. These errors usually show messages like “404 Not Found” or “400 Bad Request.”
Server-side errors occur on the web server. They arise from problems in the code, database, or server setup. These errors include 500 Internal Server Error or 503 Service Unavailable. They require developers to check logs and fix code or server settings.
| HTTP Status Code | Type | Meaning |
|---|---|---|
| 400 | Client-side | Bad Request: The request is invalid or malformed. |
| 404 | Client-side | Not Found: The requested resource does not exist. |
| 500 | Server-side | Internal Server Error: Something went wrong on the server. |
| 503 | Server-side | Service Unavailable: The server is temporarily down or busy. |

Implementing Try-catch Blocks
Try-catch blocks help catch errors before they break the app. Use them around code that might fail. Keep the try block short and clear. Catch only specific exceptions to avoid hiding bugs. Avoid empty catch blocks; always handle or log the error.
Logging exceptions helps track problems quickly. Use a centralized logging system to store error details. Include error message, stack trace, and user info if possible. This data helps fix issues faster. Avoid logging sensitive user data for privacy.
Custom Error Pages
Creating user-friendly error views helps visitors understand problems. These views show simple messages instead of confusing errors. Use clear language and gentle tones. Custom pages make your site look professional and trusted. They guide users back to safe pages or the homepage.
Configuring web.config manages how errors appear on your site. Add
Global Error Handling Techniques
Application_Error in Global.asax catches unhandled exceptions globally. It helps log errors and show friendly messages to users. This method runs after any controller or action error. Developers add custom logic inside this event to manage exceptions centrally. It reduces code repetition in controllers. Useful for logging errors in one place.
Exception Filters provide another way to handle errors in ASP.NET MVC. They catch exceptions at the action or controller level. Filters can be applied globally, per controller, or per action. This offers flexibility to handle different errors differently. Filters help keep error handling code clean and separated from business logic.
Tools For Monitoring And Debugging
Logging frameworks help track errors and events in ASP.NET MVC apps. Popular options include Serilog, NLog, and log4net. They capture important details like error messages, stack traces, and user actions. This data helps developers find and fix bugs faster.
Performance monitoring tools measure app speed and responsiveness. Tools like Application Insights and New Relic show how the app behaves under different loads. They provide reports on slow pages, database calls, and memory use. This information helps improve the user experience.
