Microsoft.Win32.SafeHandles NamespaceContains classes that are abstract derivations of safe handle classes that provide common functionality supporting file and operating system handles.
System NamespaceContains fundamental classes and base classes that define commonly-used value and reference data types, events and event handlers, interfaces, attributes, and processing exceptions.
System.CodeDom.Compiler NamespaceContains types for managing the generation and compilation of source code in supported programming languages. Code generators can each produce source code in a particular programming language based on the structure of Code Document Object Model (CodeDOM) source code models consisting of elements provided by the System.CodeDom namespace.
System.Collections NamespaceContains interfaces and classes that define various collections of objects, such as lists, queues, bit arrays, hash tables and dictionaries.
System.Collections.Concurrent NamespaceProvides several thread-safe collection classes that should be used in place of the corresponding types in the System.Collections and System.Collections.Generic namespaces whenever multiple threads are accessing the collection concurrently. However, access to elements of a collection object through extension methods or through explicit interface implementations are not guaranteed to be thread-safe and may need to be synchronized by the caller.
System.Collections.Generic NamespaceContains interfaces and classes that define generic collections, which allow users to create strongly typed collections that provide better type safety and performance than non-generic strongly typed collections.
System.Collections.Immutable NamespaceContains interfaces and classes that define immutable collections.
System.Collections.ObjectModel NamespaceContains classes that can be used as collections in the object model of a reusable library. Use these classes when properties or methods return collections.

With these stores, you can read and write data that less trusted code cannot access and prevent the exposure of sensitive information that can be saved elsewhere on the file system. Data is stored in compartments that are isolated by the current user and by the assembly in which the code exists. Additionally, data can be isolated by domain. Roaming profiles can be used in conjunction with isolated storage so isolated stores will travel with the user's profile. The IsolatedStorageScope enumeration indicates different types of isolation. For more information about when to use isolated storage, see Isolated Storage.

Classes in the System.Net namespace can be used to develop Windows Store apps or desktop apps. When used in a Windows Store app, classes in the System.Net namespace are affected by network isolation feature, part of the application security model used by the Windows Developer Preview. The appropriate network capabilities must be enabled in the app manifest for a Windows Store app for the system to allow network access by a Windows Store app. For more information, see the Network Isolation for Windows Store Apps.
System.Net.Http NamespaceProvides a programming interface for modern HTTP applications.
System.Net.Http.Headers NamespaceProvides support for collections of HTTP headers used by the System.Net.Http namespace.
