StyleCop.Analyzers.Unstable by: Sam Harwell et. al.

An implementation of StyleCop's rules using Roslyn analyzers and code fixes

System.Collections.NonGeneric by: Microsoft

Provides classes that define older non-generic collections of objects, such as lists, queues, hash tables and dictionaries. Developers should prefer the generic collections in the System.Collections package. Commonly Used Types: System.Collections.ArrayList System.Collections.Hashtable System.Collections.CollectionBase System.Collections.ReadOnlyCollectionBase System.Collections.Stack System.Collections.SortedList System.Collections.DictionaryBase System.Collections.Queue System.Collections.Comparer System.Collections.CaseInsensitiveComparer

System.Binary by: Microsoft Corporation

Non-allocating ninary reader and writer

Swagger.Net by: Mike Trionfo

Documents the ASP.NET Web API using the Swagger specification. Swagger.Net targets .NET 4.0 and will expose any apis the inherit from the ApiController in the new ASP.NET Web API. Swagger.NET aims to conform to the Swagger specification to support all swagger components including client code gen.

System.ComponentModel by: Microsoft

Provides interfaces for the editing and change tracking of objects used as data sources. Commonly Used Types: System.ComponentModel.CancelEventArgs System.IServiceProvider System.ComponentModel.IEditableObject System.ComponentModel.IChangeTracking System.ComponentModel.IRevertibleChangeTracking

System.Collections.Immutable by: Microsoft

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>

Seamlessly adds a Swagger to WebApi projects!

Swagger.Net.UI by: Mike Trionfo

Swagger UI is written by the wordnik folks and allows one to interact with a REST API that is documented using the Swagger spec (including swagger's code gen tools). This package makes the latest available for the .NET community. This is packaged with a pre-release version of Swagger.Net which emits the Swagger spec for the ASP.NET Web API. NOTE: Currently broken in IE. Use in other browser.

System.Collections.Sequences by: Microsoft Corporation

Non-allocating collections

System.Collections.Concurrent by: Microsoft

Provides several thread-safe collection classes that should be used in place of the corresponding types in the System.Collections.NonGeneric and System.Collections packages whenever multiple threads are accessing the collection concurrently. Commonly Used Types: System.Collections.Concurrent.ConcurrentDictionary<TKey, TValue> System.Collections.Concurrent.ConcurrentQueue<T> System.Collections.Concurrent.ConcurrentBag<T> System.Collections.Concurrent.BlockingCollection<T> System.Collections.Concurrent.ConcurrentStack<T>

System.Collections by: Microsoft

Provides classes that define generic collections, which allow developers to create strongly typed collections that provide better type safety and performance than non-generic strongly typed collections. Commonly Used Types: System.Collections.Generic.List<T> System.Collections.Generic.Dictionary<TKey, TValue> System.Collections.Generic.Queue<T> System.Collections.Generic.Stack<T> System.Collections.Generic.HashSet<T> System.Collections.Generic.LinkedList<T> System.Collections.Generic.EqualityComparer<T> System.Collections.Generic.Comparer<T> System.Collections.Generic.SortedDictionary<TKey, TValue>

System.AppContext by: Microsoft

Provides the System.AppContext class, which allows access to the BaseDirectory property and other application specific data. Commonly Used Types: System.AppContext

System.Buffers by: Microsoft

Provides resource pooling of any type for performance-critical applications that allocate and deallocate objects frequently. Commonly Used Types: System.Buffers.ArrayPool<T> 7601f4f6225089ffb291dc7d58293c7bbf5c5d4f When using NuGet 3.x this package requires at least version 3.4.

structuremap by: Jeremy Miller

StructureMap is a Dependency Injection / Inversion of Control tool for .Net that can be used to improve the architectural qualities of an object oriented system by reducing the mechanical costs of good design techniques. StructureMap can enable looser coupling between classes and their dependencies, improve the testability of a class structure, and provide generic flexibility mechanisms. Used judiciously, StructureMap can greatly enhance the opportunities for code reuse by minimizing direct coupling between classes and configuration mechanisms.

System.Collections.Immutable.Net40 by: Microsoft Corporation

Retargeted for .Net 4.0. Unofficial, unsupported build https://github.com/jlanng/ImmutableCollectionsNet40

System.Collections.Specialized by: Microsoft

Provides older specialized non-generic collections; for example, a linked list dictionary, a bit vector, and collections that contain only strings. Commonly Used Types: System.Collections.Specialized.NameValueCollection System.Collections.Specialized.NameObjectCollectionBase System.Collections.Specialized.StringCollection System.Collections.Specialized.IOrderedDictionary System.Collections.Specialized.HybridDictionary System.Collections.Specialized.OrderedDictionary System.Collections.Specialized.ListDictionary System.Collections.Specialized.StringDictionary System.Collections.Specialized.BitVector32
