List<T> is a growable heap collection; Span<T> and ReadOnlySpan<T> are stack-only views over memory you already own. Use List<T> for anything you store, return from async, or grow; Span<T> for a mutable allocation-free view in a synchronous method; ReadOnlySpan<T> for read-only parsing over strings, u8 literals, and slices.

Independently Releasing Multiple NuGet Packages with MinVer + Trusted Publishing

One repo, three NuGet packages, independent versions. Per-package MinVer tag prefixes, a tag-driven GitHub Actions release that publishes via OIDC trusted publishing (no API key), pinning a cross-package dependency to a real version, and the default-branch gotcha that silently swallows your first tag.

lock vs Monitor vs SemaphoreSlim vs System.Threading.Lock in C#

Four ways to guard a critical section in C#, and a decision matrix for picking one. Use System.Threading.Lock for synchronous mutual exclusion on .NET 9+, SemaphoreSlim when the section spans an await, and Monitor only when you need Wait/Pulse.
