System.Memory 4.6.3

About

Provides types for efficient representation and pooling of managed, stack, and native memory segments and sequences of such segments, along with primitives to parse and format UTF-8 encoded text stored in those memory segments.

Main Types

The main types provided by this library are:

  • System.Span
  • System.ReadOnlySpan
  • System.Memory
  • System.ReadOnlyMemory
  • System.Buffers.MemoryPool
  • System.Buffers.ReadOnlySequence
  • System.Buffers.Text.Utf8Parser
  • System.Buffers.Text.Utf8Formatter

Additional Documentation

The types in this assembly are shipped as part of the shared framework starting with .NET Core 3.1.

Microsoft.Win32.Registry
Provides support for accessing and modifying the Windows Registry. Commonly Used Types: Microsoft.Win32.RegistryKey Microsoft.Win32.Registry Microsoft.Win32.RegistryValueKind Microsoft.Win32.RegistryHive Microsoft.Win32.RegistryView When using NuGet 3.x this package requires at least version 3.4.

System.Text.Encoding.CodePages
Provides support for code-page based encodings, including Windows-1252, Shift-JIS, and GB2312. Commonly Used Types: System.Text.CodePagesEncodingProvider

System.Collections.Immutable
This package provides collections that are thread safe and guaranteed to never change their contents, also known as immutable collections. Like strings, any methods that perform modifications will not change the existing instance but instead return a new instance. For efficiency reasons, the implementation uses a sharing mechanism to ensure that newly created instances share as much data as possible with the previous instance while ensuring that operations have a predictable time complexity. Commonly Used Types: System.Collections.Immutable.ImmutableArray System.Collections.Immutable.ImmutableArray<T> System.Collections.Immutable.ImmutableDictionary System.Collections.Immutable.ImmutableDictionary<TKey,TValue> System.Collections.Immutable.ImmutableHashSet System.Collections.Immutable.ImmutableHashSet<T> System.Collections.Immutable.ImmutableList System.Collections.Immutable.ImmutableList<T> System.Collections.Immutable.ImmutableQueue System.Collections.Immutable.ImmutableQueue<T> System.Collections.Immutable.ImmutableSortedDictionary System.Collections.Immutable.ImmutableSortedDictionary<TKey,TValue> System.Collections.Immutable.ImmutableSortedSet System.Collections.Immutable.ImmutableSortedSet<T> System.Collections.Immutable.ImmutableStack System.Collections.Immutable.ImmutableStack<T>

System.Reflection.Metadata
This package provides a low-level .NET (ECMA-335) metadata reader and writer. It's geared for performance and is the ideal choice for building higher-level libraries that intend to provide their own object model, such as compilers. The metadata format is defined by the ECMA-335 - Common Language Infrastructure (CLI) specification. The System.Reflection.Metadata library is built-in as part of the shared framework in .NET Runtime. The package can be installed when you need to use it in other target frameworks.

Microsoft.Extensions.Logging.Abstractions
Logging abstractions for Microsoft.Extensions.Logging. Commonly Used Types: Microsoft.Extensions.Logging.ILogger Microsoft.Extensions.Logging.ILoggerFactory Microsoft.Extensions.Logging.ILogger<TCategoryName> Microsoft.Extensions.Logging.LogLevel Microsoft.Extensions.Logging.Logger<T> Microsoft.Extensions.Logging.LoggerMessage Microsoft.Extensions.Logging.Abstractions.NullLogger

System.Text.Encoding.CodePages
Provides support for code-page based encodings, including Windows-1252, Shift-JIS, and GB2312. Commonly Used Types: System.Text.CodePagesEncodingProvider

Microsoft.CodeAnalysis.Compilers
Compiler layer of the .NET Compiler Platform ("Roslyn"). Install this package to get both C# and Visual Basic support. If you want just support for one language, install Microsoft.CodeAnalysis.CSharp or Microsoft.CodeAnalysis.VisualBasic. More details at https://aka.ms/roslyn-packages This package was built from the source at https://github.com/dotnet/roslyn/commit/e482b6e281d7db727fcb086ebbfae44dcba82c6d.
