Common Design Patterns Uses in .Net World

  Common Design Patterns 1.       Singleton Pattern : Scenario : In a logging service for an e-commerce platform, you want to ensure that there is only one instance of the logger throughout the application to maintain consistent logging behavior and manage resources efficiently. 2.       Factory Pattern : Scenario : A payment processing system needs to create different types of payment gateways (e.g., PayPal, CreditCard) based on user preferences. Using a factory pattern, you can encapsulate the logic for creating these objects and provide a uniform interface to interact with them. 3.       Builder Pattern : Scenario : You're developing a report generation module where reports can have different formats (e.g., PDF, Excel). The builder pattern allows you to construct complex report objects step by step and produce dif...

Limitations of If Else Statements in ServiceNow Flow Designer

The ServiceNow Flow Designer is a powerful tool for automating workflows and processes. However, the If Else statement within the Flow Designer has certain limitations that users must be aware of, particularly when it comes to complex conditions, nesting, performance, debugging, user interface, maintenance, and scalability. Complex Conditions A significant limitation of the If Else statement in ServiceNow Flow Designer is its handling of complex logical operators. The Flow Designer supports basic conditions, but it may not handle operators like AND, OR, and NOT as intuitively as some other platforms. Combining multiple conditions can sometimes become cumbersome, making it challenging to implement sophisticated business logic effectively. Nested If Else Statements While it is possible to nest If Else statements within the Flow Designer, there is a practical limit to how deeply they can be nested. Excessive nesting can lead to a cluttered and hard-to-read flow, making it difficult to man...

.Net Core Empty Project - [Project].csproj file explained

The [Project].csproj file is an automatically generated project file that you’ll encounter and work with in your .NET Core project. In this particular scenario, I’m using an empty project template, which means my .csproj file contains minimal, auto-generated content.  Before we start adding code throughout the project, it’s essential to understand the default content of this file. This blog post aims to explore precisely that. If you initiate the project correctly, you will see content like this in your .csproj file. < Project Sdk = "Microsoft.NET.Sdk.Web" >   < PropertyGroup >     < TargetFramework > net8.0 </ TargetFramework >     < Nullable > enable </ Nullable >     < ImplicitUsings > enable </ ImplicitUsings >   </ PropertyGroup > </ Project > We'll take a look line by line < Project Sdk = "Microsoft.NET.Sdk.Web" > At the parent tag, you can see a property named SDK, and...
