Cheat Sheet
- CLR Data Types: Value vs Reference -
The Common Language Runtime (CLR) categorizes data into value types and reference types (Microsoft Docs). Value types like int and struct store data directly, while reference types like string and class store a pointer to heap memory. Remember: "Value lives where it is defined, Reference points afar" as a mnemonic.
- Control Flow & Exception Handling -
Master if/else, switch, loops and the try/catch/finally pattern as outlined in the official C# specification. Use the switch expression in C# 8+ for concise matching, for example:
result = day switch { Day.Monday => "Start", _ => "Other" };. As recommended by Microsoft Docs, always catch specific exceptions before general ones to maintain clarity. - OOP Foundations: Classes, Interfaces & Polymorphism -
Understand classes, structs, inheritance, interfaces and polymorphism according to the .NET documentation. Remember the PIE mnemonic - Polymorphism, Inheritance, Encapsulation - to organize key concepts. For example, override a virtual method in a derived class using
public override void Method()to implement runtime polymorphism. - LINQ & Lambda Expressions -
Leverage Language-Integrated Query (LINQ) to query collections declaratively, as shown in MSDN guides. Example:
var evens = numbers.Where(n => n % 2 == 0).ToList();uses a lambda for filtering. Practice both query syntax and method syntax to maximize readability and performance. - Async/Await & Task-based Programming -
Write non-blocking code using the async and await keywords per .NET official docs. For instance,
async Task<int> FetchDataAsync()returns a Task that you await withvar data = await FetchDataAsync();. Familiarize yourself with ConfigureAwait(false) to avoid deadlocks in UI or server applications.
