Use Memory<byte> and ArrayPool<byte>.Shared to read a file in 4KB chunks without re-allocating buffers per iteration. No async.

Convert a Guid to a base64 url-safe string (no padding, '+' → '-', '/' → '_') and back. Round-trip test.

Use a yield return iterator method to lazily enumerate Fibonacci numbers up to a given limit. Show the caller using foreach with a take of 10.

Demonstrate await on Task.Delay inside an async method that returns Task<int>. Show calling it twice in parallel via Task.WhenAll.

Write a custom equality comparer (IEqualityComparer<Person>) that treats two Person records as equal when Email lowercased matches. Include GetHashCode.

Implement nullable reference type annotations on a 'Person' class with FirstName (non-null), MiddleName (nullable), LastName (non-null). Show a constructor that enforces non-nullness.

Show typeof(T) vs T.GetType() inside a generic method. Demonstrate typeof(T) is the static declared type and GetType() is the runtime type for boxed values.

Use Random.Shared to pick a random element from a List<T> in a generic Pick<T>(List<T>) extension method.

Use DateTime.UtcNow plus a TimeSpan to compute a deadline 7 business days from now, skipping Saturday and Sunday.

Write a Regex that matches IPv4 addresses in the form '1.2.3.4' (each octet 0–255). Use Regex.Match on a sample string.

Define an interface IShape with one method Area(). Implement Circle and Rectangle records. Show a List<IShape> being summed via LINQ Sum.

Write an extension method on IEnumerable<T> called 'Chunk(int size)' that yields IEnumerable<T> chunks of the given size. Do not call the built-in Enumerable.Chunk.

Use StringBuilder to format a CSV row from an array of object?, treating null as empty. Escape any commas in values by wrapping in quotes.

Implement IComparable<T> on a 'SemVer' struct (Major, Minor, Patch). Show sorting a List<SemVer>.

Write a ReadOnlySpan<byte>-based UTF-8 BOM check: return true if the span starts with the bytes 0xEF 0xBB 0xBF.
