System.Collections.Immutable 6.0.0

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.Diagnostics.Runtime
ClrMD is a set of advanced APIs for programmatically inspecting a crash dump of a .NET program much in the same way that the SOS Debugging Extensions (SOS) do. This allows you to write automated crash analysis for your applications as well as automate many common debugger tasks. In addition to reading crash dumps ClrMD also allows supports attaching to live processes.
