Are you experiencing these Design issues? Your application code is so rigid to accommodate new changes! making it difficult to modify the system as a whole If you make changes to one part of the system it can have unexpected and far-reaching consequences in other parts of the system! You are unable to write Unit tests or if you can but those are not enough to cover the complete component functionality! You are not able to reuse the common code base across your code base due to tight coupling! If you are facing all or any such issues in your day-to-day life then this is the right place to find the solution to your problem. Lack of modularity and loose-coupling can lead to software that is difficult to understand, maintain, and extend, and can limit its potential for reuse and scalability.  An answer is: Component-Based Software Design Breaking down the Softwa...

Introduction .Net provides lots of types of Timer classes that you, as a developer, probably have come across in your day-to-day work. Below is the list:  System.Web.UI.Timer System.Windows.Forms.Timer System.Timers.Timer System.Threading.Timer System.Windows.Threading.DispatcherTimer .NET 6 introduces one more timer class, called PeriodicTimer . It doesn't rely on callbacks and instead waits asynchronously for timer ticks. So, if you don't want to use the callbacks as it has their own flaws PeriodicTimer  is a good alternative. You can create the new PeriodicTimer instance by passing the one argument, Period the time interval in milliseconds between invocations How to use Periodic Timer You can call the WaitForNextTickAsync  method in an infinite for or while loop to wait asynchronously between ticks. Example Let's write a small console application with two methods having their own ...
