2. Mastering C# and .NET Fundamentals

C# is a modern, object-oriented programming language developed by Microsoft. It was first introduced in 2002 as part of Microsoft’s .NET framework. It is a simple, powerful, and type-safe programming language used to build desktop, web, game, and mobile applications. It supports both static and dynamic typing. It is a very versatile programming language that is continuously evolving. Therefore, a .NET or a C# developer must remain up to date with the changes.

C# Language Features

• Variables, data types, and operators
• Control flow (conditionals, loops)
• Object-oriented programming (classes, objects, inheritance, polymorphism)
• Exception handling
• Delegates and events
• Generics
• LINQ (Language Integrated Query)
• Async and await for asynchronous programming

NET Libraries and APIs

.NET provides a rich set of libraries and APIs for various tasks, such as:

• Collections and data structures
• File I/O and serialization
• Networking and web requests
• Threading and task parallelism
• Security and cryptography

Getting a hold of these libraries and APIs will enable you to write efficient and maintainable code in your .NET applications.

3. Data Access with Entity Framework and Entity Framework Core

Data access is a critical aspect of application development, and Entity Framework (EF) simplifies this process for .NET developers. Let's look at how to work with databases using EF and EF Core.

Database Fundamentals

You must have a fundamental clearance of the concepts related to databases like the various operations performed on them.

• SQL and relational database concepts (tables, columns, rows, keys, indexes, and relationships)
• CRUD operations (Create, Read, Update, Delete)
• Joins, transactions, and stored procedures

Working with Entity Framework

Entity Framework (EF) simplifies data access in .NET applications by allowing developers to work with databases using objects and LINQ queries. Key concepts to learn when working with EF include:

• DbContext and DbSet for managing database connections and querying data
• Code-First and Database-First approaches for defining data models
• Migrations for managing database schema changes
• Querying data using LINQ and raw SQL
• Tracking changes and saving data

Entity Framework Core

Entity Framework Core (EF Core) is the lightweight, high-performance version of EF designed for .NET Core applications. While there are many similarities between EF Core and EF, there are also some differences and new features like:

• Improved performance and reduced memory usage
• Support for new database providers and platforms
• Simplified configuration and dependency injection
• Global query filters and query types for advanced querying scenarios

4. Application Architecture and Design Patterns

SOLID Principles

SOLID is an acronym representing five key design principles for writing maintainable and scalable code:

1. Single Responsibility Principle (SRP)
2. Open/Closed Principle (OCP)
3. Liskov Substitution Principle (LSP)
4. Interface Segregation Principle (ISP)
5. Dependency Inversion Principle (DIP)

Other Design Principles and Patterns

In addition to SOLID, other important design principles and patterns one must know are:

• GOF 23 Design Pattern
• DRY (Don’t Repeat Yourself)
• KISS (Keep It Simple, Stupid)
• MVC (Model-View-Controller)
• Repository pattern
• Unit of Work pattern

Microservices Architecture

Microservices Architecture is a method of software development, where we break down an application into small, independent, and loosely coupled services. These services are developed, deployed, and maintained by a small team of developers. These services have a separate codebase that is managed by a small team of developers. Major concepts of architecture are:

• Cloud providers (Azure, AWS, etc.)
• Docker and containerization
• Kubernetes for container orchestration
• Message buses and event-driven architecture
• API gateways and service discovery
