Reduced FIPS impact on Cryptography. In previous versions of .NET Framework, managed cryptographic provider classes such as SHA256Managed throw a CryptographicException when the system cryptographic libraries are configured in "FIPS mode". These exceptions are thrown because the managed versions of the cryptographic provider classes, unlike the system cryptographic libraries, have not undergone FIPS (Federal Information Processing Standards) 140-2 certification. Because few developers have their development machines in FIPS mode, the exceptions are commonly thrown in production systems.
.NET Standard defines a set of APIs that must be available on each .NET implementation that supports that version of the standard. .NET Framework 4.7.1 fully supports .NET Standard 2.0 and adds about 200 APIs that are defined in .NET Standard 2.0 and are missing from .NET Framework 4.6.1, 4.6.2, and 4.7. (Note that these versions of .NET Framework support .NET Standard 2.0 only if additional .NET Standard support files are also deployed on the target system.) For more information, see "BCL - .NET Standard 2.0 Support" in the .NET Framework 4.7.1 Runtime and Compiler Features blog post.

In .NET Framework 4.7 and earlier versions, the Message.HashAlgorithm property supported values of HashAlgorithm.Md5 and HashAlgorithm.Sha only. Starting with .NET Framework 4.7.1, HashAlgorithm.Sha256, HashAlgorithm.Sha384, and HashAlgorithm.Sha512 are also supported. Whether this value is actually used depends on MSMQ, since the Message instance itself does no hashing but simply passes on values to MSMQ. For more information, see the "SHA-2 support for Message.HashAlgorithm" section in the .NET Framework 4.7.1 ASP.NET and Configuration features blog post.
ASP.NET processes requests in a predefined pipeline that includes 23 events. ASP.NET executes each event handler as an execution step. In versions of ASP.NET up to .NET Framework 4.7, ASP.NET can't flow the execution context due to switching between native and managed threads. Instead, ASP.NET selectively flows only the HttpContext. Starting with .NET Framework 4.7.1, the HttpApplication.OnExecuteRequestStep(Action) method also allows modules to restore ambient data. This feature is targeted at libraries concerned with tracing, profiling, diagnostics, or transactions, for example, that care about the execution flow of the application. For more information, see the "ASP.NET Execution Step Feature" in the .NET Framework 4.7.1 ASP.NET and Configuration Features blog post.
In .NET Framework 4.7, the DataContractJsonSerializer class serializes control characters in conformity with the ECMAScript 6 standard. This behavior is enabled by default for applications that target .NET Framework 4.7, and is an opt-in feature for applications that are running under .NET Framework 4.7 but target a previous version of .NET Framework. For more information, see the Application compatibility section.
In previous versions of .NET Framework, WPF applications can't opt into the focus tracking without disabling WPF pen/touch gesture support. As a result, WPF applications must choose between full WPF touch support or rely on Windows mouse promotion.
The Workflow Designer, FlowChart Activity Designer, and other Workflow Activity Designers now successfully load and display workflows that have been saved after calling the DynamicUpdateServices.PrepareForUpdate method. In versions of the .NET Framework before .NET Framework 4.6.2, loading a XAML file in Visual Studio for a workflow that has been saved after calling DynamicUpdateServices.PrepareForUpdate can result in the following issues:
For apps that target .NET Framework 4.6, Task and Task objects inherit the culture and UI culture of the calling thread. The behavior of apps that target previous versions of .NET Framework, or that do not target a specific version of .NET Framework, is unaffected. For more information, see the "Culture and task-based asynchronous operations" section of the CultureInfo class topic.
Automatic binding redirection for assemblies. Starting with Visual Studio 2013, when you compile an app that targets .NET Framework 4.5.1, binding redirects may be added to the app configuration file if your app or its components reference multiple versions of the same assembly. You can also enable this feature for projects that target older versions of .NET Framework. For more information, see How to: Enable and Disable Automatic Binding Redirection.
The Portable Class Library project in Visual Studio 2012 (and later versions) enables you to write and build managed assemblies that work on multiple .NET Framework platforms. Using a Portable Class Library project, you choose the platforms (such as Windows Phone and .NET for Windows 8.x Store apps) to target. The available types and members in your project are automatically restricted to the common types and members across these platforms. For more information, see Portable Class Library.

Beginning in 1988 with DR-DOS, several competing products were released for the x86 platform,[5] and MS-DOS went through eight versions, until development ceased in 2000.[6] Initially, MS-DOS was targeted at Intel 8086 processors running on computer hardware using floppy disks to store and access not only the operating system, but application software and user data as well. Progressive version releases delivered support for other mass storage media in ever greater sizes and formats, along with added feature support for newer processors and rapidly evolving computer architectures. Ultimately, it was the key product in Microsoft's development from a programming language company to a diverse software development firm, providing the company with essential revenue and marketing resources. It was also the underlying basic operating system on which early versions of Windows ran as a GUI.
On microcomputers based on the Intel 8086 and 8088 processors, including the IBM PC and clones, the initial competition to the PC DOS/MS-DOS line came from Digital Research, whose CP/M operating system had inspired MS-DOS. In fact, there remains controversy as to whether QDOS was more or less plagiarized from early versions of CP/M code. Digital Research released CP/M-86 a few months after MS-DOS, and it was offered as an alternative to MS-DOS and Microsoft's licensing requirements, but at a higher price. Executable programs for CP/M-86 and MS-DOS were not interchangeable with each other; many applications were sold in both MS-DOS and CP/M-86 versions until MS-DOS became preponderant (later Digital Research operating systems could run both MS-DOS and CP/M-86 software). MS-DOS originally supported the simple .COM, which was modeled after a similar but binary-incompatible format known from CP/M-80. CP/M-86 instead supported a relocatable format using the file extension .CMD to avoid name conflicts with CP/M-80 and MS-DOS .COM files. MS-DOS version 1.0 added a more advanced relocatable .EXE executable file format. 2ff7e9595c
