Testing and Debugging, ANGULAR WITH CORE .NET AND MVC RAZOR ENGINE                                                Testing & Debugging Here I'll brief some important points on debugging and why it is essential. as well as dive into the implementation details for creating  unit and integration tests. Why Is Testing Important? Since from last few years, software testing has become an integral part of product quality assurance (QA). We all do some level of testing(Manual or Automation) of our code before deploying it to a production environment, be it a simple little quick-and-dirty exploratory testing or full-blown automated testing that covers nearly 104 percent of the code. One can imagine what would happen if car companies just designed, built, and released their vehicles without first doing som...

API Security , ANGULAR WITH CORE .NET AND MVC RAZOR ENGINE                                 Security Implementation in API Having APIs everywhere is excellent, but they need to be secure externally as well as internally. Even a small breach has the potential risk of a damaging ripple effect. API security is not limited to authentication or authorization but also includes protecting the underlying infrastructure, like rate limiting to prevent denial of service (dos) or distributed denial of service (DDoS) attacks. Attackers continuously come up with new and creative ways to breach systems, and it’s important to keep on standard and up-to-date with the latest threats out there. ASP.NET Core offers a wide range of features to help us configure and manage the security of our APIs. The framework provides a rich identity model for securing applicatio...

Logging and Error Handling | Exception Handling , ANGULAR WITH CORE .NET AND MVC RAZOR ENGINE   Logging and Error Handling | Exception handling Mechanism Application logging plays a crucial role in tracking and identifying issues that may  surface as well as in providing useful insights into the workflow processes of solutions. When things go wrong, one of the first sources to look at is the application’s log. Depending on the number of details that are logged, each entry represents an action that occurred at a specific date and time. Logs can contain system-generated events as well as events explicitly defined by the developer and are usually grouped into categories like errors, informational, and warning. Application logs are application-specific, hence the name, and do not often include OS-specific events. Let's begin Adding Logging  Logging can be used anywhere in ASP.NET Core, and to create a log we merely need to...

Configuration Model in c# , ANGULAR WITH CORE .NET AND MVC RAZOR ENGINE  Configuration Model Configuration data should live outside the application. If you feel the urge to hardcode something, stop and think about the impact it may have on the scalability of the application in the future. When we separate the configuration from the application, it allows us to deploy the same code to do different things in different environments  There is a saying " Don’t code hard, hardcode instead.” As .NET developers, we should be familiar with the good old app.config and web. config files, which offer a mechanism for a specific configuration for each application. ASP.NET Core is no different, but with a much better mechanism for storing and providing configuration data. In fact, the new configuration model in ASP.NET Core is much more simplified, flexible, and extendable. Compared to its predecessors, it sets the bar quite high. In laymen’s term...

MVC Pattern , ANGULAR WITH CORE .NET AND MVC RAZOR ENGINE                                                              Introduction This chapter will focus on the implementation of the MVC pattern within ASP.NET Core, specifically from an API perspective as a fully functional web framework. We will explore how data are mapped from HTTP requests and bound to action parameters and strongly typed models, as well as how these models are validated before any data processing happens. At the end of this chapter, we will also have a broader understanding of how controllers work and grasp the importance of action methods to handle incoming requests. We will learn all about filters and how they can help by executing code before and after the processing of requests in the pi...
