Law of Demeter (LoD) Principle Using C#

 The Law of Demeter (LoD) principle, also known as the Principle of Least Knowledge, is a software development principle that encourages developers to minimize the coupling between objects in a software system. The principle states that an object should have limited knowledge of the internal structure or workings of other objects in the system.

In practice, the LoD principle requires developers to design software systems in a way that limits the number of direct relationships between objects. Instead of allowing objects to directly access and manipulate the properties or methods of other objects, developers should use intermediary objects or interfaces to facilitate communication between objects.

By minimizing the coupling between objects, developers can reduce the risk of creating tight dependencies between different parts of the system. This can make the system more modular, easier to test, and more resilient to changes in the system. The LoD principle also promotes encapsulation, as objects are not exposed to the internal details of other objects.

The LoD principle is often used in object-oriented programming (OOP) and is closely related to other design principles such as the Single Responsibility Principle (SRP) and the Interface Segregation Principle (ISP). By following these principles, developers can create flexible, maintainable, and extensible software systems.

Overall, the Law of Demeter principle is a key principle in software engineering that helps developers write modular, encapsulated, and loosely coupled code. By minimizing the direct relationships between objects in the system, developers can create software that is easier to understand, modify, and test.

How to use Enum Data Values with .Net 6.0 Framework and Entity Framework Core 6

How to use Enum Data Values with .Net 6.0 Framework and Entity Framework Core 6 Overview An Enum (Enumeration) is a group of constants that are read-only value types. By default, the first value of the Enum variable is 0 i.e. Here we will create an Enum of Priorities type with read-only values of Highest, Normal and Low. We will set the read-only values using an integer assigning a number next to the value. By default, the integer value will start with 0. Here we will be assigning the integer value next to the Enum value such as in the below example and we will use a comma (,) to separate the item in the list of Enum(Enumeration).  We create Enum by using the Enum keyword and then using class, interface, and abstract. The reason we use an Enum is to ensure we improve our application performance and improve application readability, and maintainability, and reduces the complexity of the application hence why if you take a look at the example below of Status (NotStarted, Started, Complete

A Complete Guide to Using GUIDs in C# with Code Examples

  Overview In this post, we are looking at GUIDs (Globally Unique Identifiers), which are widely used in C# for generating unique identifiers for objects, entities, and resources in a system. In this post, we'll explore the basics of GUIDs in C#, their advantages, and how to convert strings to GUIDs. In this post, we have used Guid Generator to create the GUID from the following URL Address What is GUID GUID (Globally Unique Identifier) in C# is a 128-bit value that is used to identify objects, entities, or resources in a unique manner across different systems and applications. It is also known as UUID (Universally Unique Identifier) in some other programming languages.   GUIDs are generated using a combination of unique factors such as the MAC address of the network adapter, the current time and date, and a random number. The resulting GUID is a string of 32 hexadecimal digits separated by hyphens, such as "b86f2096-237a-4059-8329-1bbcea72769b&

Primitives Data Types and None-Primitives Data Types in C# with Code Examples

  Overview I wrote this post to provide an explanation of primitive and non-primitive data types in C#. C# is a strongly typed programming language, where each variable and expression must have a specific data type. C# data types are categorized into two primary groups: primitive data types and non-primitive data types. Primitive data types are the simplest data types available in programming languages. They are typically pre-defined data types and can represent a single value, such as a boolean value, character, or integer. Examples of primitive data types include int, char, float, double, and boolean, which are common in programming languages like C++, C, and Java. Non-primitive data types are also referred to as composite data types or reference data types. They are constructed from primitive data types and are more complex than primitive data types. Non-primitive data types can hold multiple values and allow for the creation of more intricate data structures like tables, lists,
