Back to reality: Shared extensions

General-purpose toolkit of utilities and extensions for everyday .NET code.

dotnet add package Rumrunner0.BackToReality.SharedExtensions

What's inside

Area Highlights
Collections Bounded counting predicates (Some, None, Many, Exactly, AtLeast, MoreThan, LessThan) that never enumerate further than needed; inclusive range removal for lists; tuple deconstruction of lists; collection-initializer Add for any ICollection<T>; reference-equality hash sets; Cycle over a collection.
Cryptography AES-256-GCM string encryption packed into a single Base64 blob (nonce\|tag\|cipher), with strict UTF-8 and zeroing of transient key material; fixed-time string equality.
Disposing DisposableGroup treats many disposables as one: reverse-order disposal, thread-safe single shot, failures collected instead of thrown.
Environment Required environment variables (GetRequired, GetRequiredInt) with culture-invariant parsing.
Exceptions Guard helpers (ThrowIfNull, ThrowIfNullOrEmpty, ThrowIfAnyNull, ...) that capture the argument expression; AggregateException-aware inner-exception search (IsOrHasInner, HasInner) and message joining (JoinMessages).
Extensions String emptiness checks, JSON validation, Base64 decoding, GUID parsing, whitespace splitting, and fluent object shaping (Shape, Chain, Follow).
Serialization JsonSerializerOptionsExtensions.BetterWeb — a shared, read-only JsonSerializerOptions preconfigured with sane web defaults.
Tasks ContinueWithoutContextCapture — ConfigureAwait(false) with a name that says what it does, for Task, Task<T>, ValueTask, and ValueTask<T>.
Time DateTimeOffset.Truncate(resolution) and TruncatedTimeProvider which is a TimeProvider truncated to microseconds for storage-friendly timestamps.
ValueObjects IValueObject<TSelf, TValue> — a minimal contract for strongly-typed value wrappers.

Some examples

Counting without over-enumerating:

using Rumrunner0.BackToReality.SharedExtensions.Collections;

var ready = requests.AtLeast(2) && requests.LessThan(100); // enumerates at most 100 items

Guards that report the caller's argument name and teach the compiler:

using Rumrunner0.BackToReality.SharedExtensions.Exceptions;

void Send(Message? message)
{
	ArgumentExceptionExtensions.ThrowIfNull(message); // ArgumentNullException with ParamName "message"
	Deliver(message.Body); // no null warning — the guard is annotated with [NotNull]
}

Symmetric encryption in one line each:

using Rumrunner0.BackToReality.SharedExtensions.Cryptography;

var key = AesGcmSymmetricEncryption.GenerateKey();           // Base64-encoded 256-bit key
var blob = AesGcmSymmetricEncryption.Encrypt("secret", key); // Base64: nonce|tag|cipher
var text = AesGcmSymmetricEncryption.Decrypt(blob, key);     // "secret"

Many disposables as one:

using Rumrunner0.BackToReality.SharedExtensions.Disposing;

using var resources = new DisposableGroup([connection, transaction, reader]);
// Disposed in reverse order; failures are collected into resources.DisposalExceptions.

Development notes

Packages from earlier releases accumulate in bin/Release, and that is expected: dotnet clean runs MSBuild's Clean target, which deletes only the build outputs recorded during the previous build, and the Pack target never records the .nupkg/.snupkg files it produces. These leftover packages are intentionally kept — do not delete them. They are harmless: Nuget/push.zsh picks the exact package file by version, so stale packages are never pushed.
