WARNING: GZip uses Deflate compression, but this hardcodes CompressionType.Deflate instead of using CompressionType.GZip.
When a custom provider is registered for GZip, this code will still use the Deflate provider for decompression. This breaks the provider abstraction for GZip files.
Consider using CompressionType.GZip here, or ensure the provider registry properly maps GZip to use the correct decompression implementation.

Pull request overview
Adds a configurable CompressionProviderRegistry that flows through SharpCompress reader/writer options so callers can swap compression stream implementations (e.g., use System.IO.Compression for GZip/Deflate) while keeping internal defaults.
Changes:
- Introduces
ICompressionProvider,CompressionProviderRegistry, andCompressionContext(plus hook/finalization interfaces) and internal default provider implementations for manyCompressionTypes. - Threads
ProvidersthroughReaderOptions/WriterOptions(and format-specific options) into ZIP/GZip/Tar read/write pipelines. - Adds docs + tests demonstrating replacing providers and validating round-trips / compatibility.

ZipFilePart.cs still imports a number of compressor implementation namespaces (BZip2/Deflate/Deflate64/Explode/LZMA/PPMd/Reduce/Shrink/Xz/ZStandard), but the refactored implementation now resolves decompression via CompressionProviderRegistry and no longer references those types. With TreatWarningsAsErrors enabled, the resulting CS8019 warnings will fail the build; remove the unused using directives.

GZipWriter used to pass WriterOptions.ArchiveEncoding.GetEncoding() into the internal SharpCompress.Compressors.Deflate.GZipStream constructor. With the new provider-based creation, internal gzip streams will always use the default UTF-8 encoding, changing the bytes written for the header filename/comment when a non-default ArchiveEncoding is configured. Consider using the provider overload that accepts a CompressionContext (e.g., pass the encoding via context.FormatOptions or a dedicated field) and update GZipCompressionProvider to honor it by calling the 4-arg GZipStream constructor.

GZipFilePart.GetCompressedStream() always resolves CompressionType.Deflate from the provider registry. That means swapping the CompressionType.GZip provider (e.g., to SystemGZipCompressionProvider) will not affect reading .gz archives via GZipArchive/GZipEntry; only replacing the Deflate provider would. If the intent is that .gz reading honors the GZip provider, this needs a different integration point (or the docs should explicitly note that .gz uses the Deflate provider).

After refactoring to provider-based compression, ZipWriter.cs no longer references several compression-implementation types directly, but the corresponding using SharpCompress.Compressors.* directives at the top of the file remain. With warnings treated as errors, the resulting “unnecessary using directive” warnings (CS8019) will fail the build; remove any now-unused compressor usings (e.g., BZip2/Deflate/LZMA/ZStandard) and keep only the ones still needed (like PPMd if referenced).

ZipWriter uses ICompressionProviderHooks for pre-stream bytes and properties, but never calls GetPostCompressionData(...). That makes it impossible for a custom provider to append required footer bytes after the compression stream completes, and also risks incorrect entry.Compressed sizing when such footers are needed. Consider capturing the selected hooks-provider + context and, in ZipWritingStream.Dispose, after disposing the compression stream but before reading counting.BytesWritten, write any post-compression bytes returned by the provider.

This assignment to gzipStream is useless, since its value is never read.

The internal GZipCompressionProvider always constructs SharpCompress.Compressors.Deflate.GZipStream with its default encoding (UTF-8). Since GZipWriter previously used WriterOptions.ArchiveEncoding, the provider should accept/consume encoding from CompressionContext (or similar) so callers can preserve non-UTF8 header encoding when needed.

The doc comment says GetProviders() “falls back to default if not set”, but _compressionProviders is required by the constructor and the method just returns the field. Either implement an actual fallback (e.g., null/optional ctor param) or adjust the comment to match behavior.

This foreach loop immediately maps its iteration variable to another variable - consider mapping the sequence explicitly using '.Select(...)'.

I've endeavoured to make sure no sync methods are used when going via the async interface (and vice versa) but you never know. Tests should cover things as well as the recent fixes (like the 7z regression) Options and the API have been revamped so expect API breakages. I think it should be straight-forward but things won't compile. There is a thing about Dispose vs async Disposing that may or may not be fully covered 😬 Feedback is welcome as I think 1.0 is around the corner with the introduction of Providers and other things.

#1196
This pull request introduces support for custom compression providers throughout the SharpCompress library, allowing users to swap out the built-in compression implementations for alternatives (such as using
System.IO.Compressionfor GZip/Deflate). The changes include updates to the API, documentation, and internal handling of compression streams to make the provider registry configurable and accessible wherever compression or decompression occurs.API and Core Library Updates:
Providersproperty of typeCompressionProviderRegistryto bothReaderOptionsandWriterOptions, allowing users to specify custom compression providers. This property defaults to the built-in registry but can be overridden as needed. [1] [2] [3]GZipFilePart,SeekableZipFilePart,StreamingZipFilePart, andZipFilePartto accept and use theCompressionProviderRegistryfor creating decompression streams, replacing hardcoded usage of built-in codecs. [1] [2] [3] [4] [5] [6] [7]Providersregistry from options to file part constructors, ensuring the custom provider is used throughout. [1] [2] [3] [4] [5] [6]Documentation Improvements:
README.md,docs/API.md, anddocs/USAGE.mdexplaining how to configure and use custom compression providers, with code samples and guidance for replacing or extending built-in codecs. [1] [2] [3]Internal Refactoring:
GZipFilePartandZipFilePartto use the provider registry, removing direct references to specific codec classes and making the implementation more flexible. [1] [2]DeflateStreamin favor of using the provider registry abstraction.These changes make it much easier to integrate alternative or third-party compression libraries, improve testability, and allow for more flexible deployment scenarios.
