C# 12 Mastery: From Console Apps to Web Development

Explore variables and data types in C# by declaring, initializing, and printing values in a Visual Studio 2022 console app, using int, string, bool, and more.

Explore arithmetic operations, logical and comparison operators, and variables in C# 12 to build foundations for program execution. Practice data manipulation and decision making with console output and string formatting.

Explore C# 12 if statements as a cornerstone of conditional flow, with age-based examples showing if, else, else if, and nested ifs, plus top level statements and console output.

Explore for, while, and do while loops in C sharp, including nested loops, and print a five by five asterisk square while learning loop syntax and iteration.

Explore switch statements to craft efficient multiway branching and replace nested ifs. Learn the basic syntax, cases, and default, plus lambda expressions enhancing switch usage in c# 12.

Explore functions and methods in C# 12, covering names, parameters, return types, static vs non-static, overloading, and how to define, call, and use them in classes.

Build a console based task manager in C# 12 by defining a Task class with id, description, due date, and a completed flag, plus a display menu for adding tasks.

Explore building an interactive console task manager in C# 12, using a while loop, switch cases, and functions to add, read, and complete tasks with id, description, and date.

Master sorting in a C# 12 task manager console app by implementing a sort function that orders tasks by ID, description, due date, or status using lambda expressions.

Explore the core pillars of object oriented programming in C# 12, including classes, instances, polymorphism, encapsulation, and inheritance, and learn how they enable modular, maintainable, and flexible code.

Define a class as a blueprint and implement dog, cat, and duck methods, make the class public for main access, and create animal instances to print woof, meow, and quack.

Master C# 12 inheritance by building a breed superclass and dog subclasses, reusing properties and methods, and overriding behavior for Snoopy’s white beagle.

Explore polymorphism in C# 12, using inheritance, method overriding, and overloading to treat diverse dog subclasses as a common base and call unified methods.

Set up a student grid tracker console project by adding grade and student models, organizing code into a models folder, and building a menu-driven user interface with input validation.

Master grade calculations in a console-based student tracker by implementing add student, overriding the to string method, formatting scores to two decimals, computing the overall average, and validating input.

Develop and test a student grade tracker by selecting students by id, validating inputs, adding grades, and computing average scores across subjects.

Demonstrate primary constructors, collection initializers, read-only reference parameters, and default lambda parameters in C# 12 to streamline object initialization and improve safety, readability, and maintenance. Explore eliason type alias.

Explore error handling in C# 12 by applying try-catch blocks to manage division by zero, format, and null reference exceptions, with precise and layered catch blocks and a final fallback.

Explore exception handling with the throw statement, implement built-in and custom exceptions, and apply best practices for robust error handling via try catch and informative messages.

Learn to perform file input and output in C# by creating and writing text files with System.IO. Read text back with ReadAllText and display it on the console.

Explore streams and IO in the system IO namespace, focusing on file streams, streamwriter and streamreader for line-by-line reading and writing, with safe resource management and exception handling.

Explore language integrated query (LINQ) in C# 12, highlighting benefits like improved readability, type safety, and unified data source querying through powerful extension methods and a declarative style.

Explore core LINQ concepts in C# using where and select to filter and project data, and use sum, average, and count to summarize collections and order by to sort results.

Apply linq in a c# 12 console app to display students, search by name, and compute statistics such as total, average, and top grade using select and where.

Learn to design graphical user interfaces with Winforms in .NET, using the designer, toolbox, and properties window to place controls, customize appearance, and generate code for a notepad app.

Add a file menu with items like new, open, save, and save as for a notepad-like app. Use submenus and event handlers to clear the text box.

Add event handlers to the file menu to open and save files using dialogs. Use stream readers and writers and track a current file path for text updates.

Wire edit and format menu event handlers in a WinForms text app to copy, cut, paste, and select all, then use font and color dialogs to style text.
