C# Lowering - What is it and why should I care?
#1about 7 minutes
Defining C# lowering and its benefits
C# lowering is the process of transforming high-level language features into simpler constructs, which simplifies the compiler and ensures predictable performance.
#2about 3 minutes
Subtle differences in property getter implementations
The `var` keyword is lowered to its inferred type, while expression-bodied properties can introduce subtle behavioral changes compared to traditional getters.
#3about 4 minutes
How `foreach` is lowered for arrays versus lists
A `foreach` loop is lowered to an index-based `while` loop for arrays but uses the `IEnumerable` pattern with a `try-finally` block for lists, impacting performance.
#4about 2 minutes
The danger of using `async` without `await` in `using` blocks
Combining `IDisposable` with an `async` call without `await` can lead to the object being disposed before the asynchronous operation completes.
#5about 9 minutes
Understanding the `yield` keyword and its performance
The `yield` keyword generates a state machine class to enable deferred execution, trading slower per-item runtime for significantly lower memory allocation.
