ASP.NET is an open-source framework based on .NET. The developers use ASP.NET to build websites, applications, and services using CSS, HTML, and JavaScript. They even write web APIs that allow JSON or XML to communicate with connected devices, including mobile devices.
ASP.NET functionality can be enhanced with the SignalR library. SignalR uses the HTML5-based WebSockets API and other APIs to easily establish dynamic multi-way communication between server and client. Microsoft also offers other frameworks to enhance further the functionality of ASP.NET, including dynamic data, data application frameworks, AJAX functionality, and an MVC (Model-View-Controller) framework for building web applications.
Need to debug the ASP.NET application
In the design and development process or the program development life cycle (PDLC), errors are bound to occur. It is essential to find and correct these errors early to minimize person-hours and avoid major development bottlenecks later on. The process of finding and correcting logical and syntactic errors in a PDLC is called debugging. The debugging process is where the programmer or developer adds breakpoints to an ASP.NET application. This breakpoint is used to stop the execution of a running program to check the correctness of the program step by step. It helps developers analyze the code sections before finalizing or fixing the code.
ASP.NET application monitoring needs
ASP.NET application monitoring activities ensure that applications work according to defined indicators, and if difficulties or errors arise, developers should get to know each other immediately before the user experience. Monitoring events are critical to maintain the application’s runtime and fix it in time in case of failure. There are several reasons to monitor ASP.NET applications, such as:
To check the availability and usage of the site The application throws an exception every time the page loads The application is working fine, but invoices or processes on the backend are not running The application can run other processes, which can consume resources and slow down the main process
It is essential for SMB (small to medium business) and large enterprises to monitor ASP.NET application response, online availability, customer response, backend process, etc., to ensure the best end-user experience and ensure better business results. At the very least, the company needs to know if the application is online and how it works at a high level. Is the site fast or slow? Are customers satisfied? This is a critical question that you must answer and monitor at all times. In the following sub-section, we will discuss tools used to debug and monitor ASP.NET applications.

Its Best features include storage, call stack, and database profiles.
Conclusion
Creating a robust application is a complex activity that involves many person-hours to do complex coding, including HTML, CSS, and JS. Building an application involves mapping entities, various libraries, database connectivity, and server response time, and a lot more. During this process, it becomes tough to understand the exact cause that is slowing down the application, so the tools and software mentioned above are helpful to make the process easier in terms of debugging, monitoring, and optimizing the performance of the application. We hope this post helped you debug and optimize the performance of ASP.NET applications. You may also be interested in knowing about ASP.NET Hosting Platforms.
