Manually Install Adobe Camera Raw Plugin Download . The . NET Framework 4.NET Framework 4. 6, 4. Downloading and installing the . NET Framework 4. 7. You can download the . NET Framework 4. 7 from the following locations: The . NET Framework 4. 7 can be installed on Windows 1. Windows 8. 1, Windows 7, and the corresponding server platforms starting with Windows Server 2. R2 SP1. You can install the . NET Framework 4. 7 by using either the web installer or the offline installer. The recommended way for most users is to use the web installer. You can target the . NET Framework 4. 7 in Visual Studio 2. NET Framework 4. 7 Developer Pack. What's new in the . NET Framework 4. 7. The . NET Framework 4. For a list of new APIs added to the . NET Framework 4. 7, see . NET Framework 4. 7 API Changes on Git. Hub. For a list of feature improvements and bug fixes in the . NET Framework 4. 7, see . NET Framework 4. 7 List of Changes on Git. Hub. For additional information, see Announcing the . NET Framework 4. 7 in the . NET Blog. Core. The . NET Framework 4. 7 improves serialization by the Data. Contract. Json. Serializer: Enhanced functionality with Elliptic Curve Cryptography (ECC)*In the . NET Framework 4. 7, Import. Parameters(ECParameters) methods were added to the ECDsa and ECDiffie. Hellman classes to allow for an object to represent an already- established key. An Export. Parameters(Boolean) method was also added for exporting the key using explicit curve parameters. The . NET Framework 4. Brainpool curve suite), and has added predefined definitions for ease- of- creation through the new Create and Create factory methods. You can see an example of . NET Framework 4. 7 cryptography improvements on Git. Hub. Better support for control characters by the Data. Contract. Json. Serializer. In the . NET Framework 4. Data. Contract. Json. Serializer serializes control characters in conformity with the ECMAScript 6 standard. This behavior is enabled by default for applications that target the . NET Framework 4. 7, and is an opt- in feature for applications that are running under the . NET Framework 4. 7 but target a previous version of the . NET Framework. For more information, see Retargeting Changes in the . NET Framework 4. 7. Networking. The . NET Framework 4. 7 adds the following network- related feature: Default operating system support for TLS protocols*The TLS stack, which is used by Ssl. Stream and up- stack components such as HTTP, FTP, and SMTP, allows developers to use the default TLS protocols supported by the operating system. Developers need no longer hard- code a TLS version. ASP. NETIn the . NET Framework 4. ASP. NET includes the following new features: Object Cache Extensibility. Starting with the . NET Framework 4. 7, ASP. NET adds a new set of APIs that allow developers to replace the default ASP. NET implementations for in- memory object caching and memory monitoring. Developers can now replace any of the following three components if the ASP. NET implementation is not adequate: Object Cache Store. By using the new cache providers configuration section, developers can plug in new implementations of an object cache for an ASP. NET application by using the new ICache. Store. Provider interface. Memory monitoring. The default memory monitor in ASP. NET notifies applications when they are running close to the configured private bytes limit for the process, or when the machine is low on total available physical RAM. When these limits are near, notifications are fired. For some applications, notifications are fired too close to the configured limits to allow for useful reactions. Developers can now write their own memory monitors to replace the default by using the Application. Monitors. Memory. Monitor property. Memory Limit Reactions. By default, ASP. NET attempts to trim the object cache and periodically call GC. Collect when the private byte process limit is near. For some applications, the frequency of calls to GC. Collect or the amount of cache that is trimmed are inefficient. Developers can now replace or supplement the default behavior by subscribing IObserver implementations to the application's memory monitor. Windows Communication Foundation (WCF)Windows Communication Foundation (WFC) adds the following features and changes: Ability to configure the default message security settings to TLS 1. TLS 1. 2. Starting with the . NET Framework 4. 7, WCF allows you to configure TSL 1. TLS 1. 2 in addition to SSL 3. TSL 1. 0 as the default message security protocol. This is an opt- in setting; to enable it, you must add the following entry to your application configuration file: < runtime>. App. Context. Switch. Overrides value="Switch. System. Service. Model. Disable. Using. Service. Point. Manager. Security. Protocols=false; Switch. System. Net. Dont. Enable. Sch. Use. Strong. Crypto=false" />. Improved reliability of WCF applications and WCF serialization. WCF includes a number of code changes that eliminate race conditions, thereby improving performance and the reliability of serialization options. These include: Better support for mixing asynchronous and synchronous code in calls to Socket. Connection. Begin. Read and Socket. Connection. Read. Improved reliability when aborting a connection with Shared. Connection. Listener and Duplex. Channel. Binder. Improved reliability of serialization operations when calling the Formatter. Services. Get. Serializable. Members(Type) method. Improved reliability when removing a waiter by calling the Channel. Synchronizer. Remove. Waiter method. Windows Forms. In the . NET Framework 4. Microsoft Remote Desktop Services Visio Stencils . Windows Forms improves support for high DPI monitors.High DPI support.Starting with applications that target the .NET Framework 4. 7, the .NET Framework features high DPI and dynamic DPI support for Windows Forms applications. High DPI support improves the layout and appearance of forms and controls on high DPI monitors. Dynamic DPI changes the layout and appearance of forms and controls when the user changes the DPI or display scale factor of a running application. High DPI support is an opt- in feature that you configure by defining a < System. Windows. Forms. Configuration. Section> section in your application configuration file. For more information on adding high DPI support and dynamic DPI support to your Windows Forms application, see High DPI Support in Windows Forms. Windows Presentation Foundation (WPF)In the . NET Framework 4. 7, WPF includes the following enhancements: Support for a touch/stylus stack based on Windows WM_POINTER messages. You now have the option of using a touch/stylus stack based on WM_POINTER messages instead of the Windows Ink Services Platform (WISP). This is an opt- in feature in the . NET Framework. For more information, see Retargeting Changes in the . NET Framework 4. 7. New implementation for WPF printing APIs. WPF's printing APIs in the Print. Queue class call the Windows Print Document Package API instead of the deprecated XPS Print API. For the impact of this change on application compatibility, see Retargeting Changes in the . NET Framework 4. 7. What's new in the . NET Framework 4. 6. The . NET Framework 4. For a list of new APIs added to the . NET Framework 4. 6. NET Framework 4. 6. API Changes on Git. Hub. For a list of feature improvements and bug fixes in the . NET Framework 4. 6. NET Framework 4. 6. List of Changes on Git. Hub. For additional information, see Announcing . NET Framework 4. 6. NET Blog. ASP. NET In the . NET Framework 4. 6. ASP. NET includes the following enhancements: Improved support for localized error messages in data annotation validators. Data annotation validators enable you to perform validation by adding one or more attributes to a class property. The attribute's Validation. Attribute. Error. Message element defines the text of the error message if validation fails. Starting with the . NET Framework 4. 6. ASP. NET makes it easy to localize error messages. Error messages will be localized if: The Validation.
