Microsoft .NET Framework 4.5.2, 4.6, and 4.6.1 will end support in April 2022
Microsoft Windows users who have Microsoft .NET version 4.5.2, 4.6, or 4.6.1 installed must install a newer version of the Microsoft Framework if they want Microsoft to support the framework through future product updates.
According to Microsoft, all three frameworks will end support on April 26, 2022. After the support date ends, the product will not receive "security fixes or technical support."
Most home devices are kept up to date through Windows Update. These devices already have newer versions of the framework installed, such as .NET Framework 4.8.
Devices that are not automatically updated may need to be manually updated to move from one of the unsupported versions to a supported version.
System administrators can update their installed Microsoft .NET Framework version to a newer version, at least Microsoft .NET Framework 4.6.2, before April to continue receiving support and security updates. Version 4.6.2 of the framework comes pre-installed on Windows 10 version 1607. Newer versions of Windows 10 include newer versions of the framework, for example, Windows 10 version 1903 includes .NET Framework version 4.8 by default.
.NET Framework 4.6.2 and later follows the operating system's lifecycle policy; this means that it will lose support when the operating system loses support.
The three .NET versions that will end support in April 2022 are affected by Microsoft's decision to retire SHA-1 in the company's products.
Microsoft is making this change because the .NET Framework previously used certificates that use Secure Hash Algorithm 1 (SHA-1) for digital signing, and we are prioritizing support for newer digital certificates.
Check the installed .NET Framework version
You may be wondering which versions of .NET Framework are installed on your Windows device. It's relatively easy to find, as you can check it in the registry by:
- Open Start, type regedit.exe, and select Windows Registry Editor from the list of results.
- Confirm UAC prompt.
- Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP. On Windows 10 and above, you can paste a path into the address field to jump directly to it.
- Check the version folder starting with v and the client or full folder. The registry string value version displays the installed .NET Framework version.
If you see that one of the listed frameworks will lose support, you may want to consider upgrading it so that your device supports that framework.
The above is the detailed content of Microsoft .NET Framework 4.5.2, 4.6, and 4.6.1 will end support in April 2022. For more information, please follow other related articles on the PHP Chinese website!

How to evaluate the cost-effectiveness of commercial support for Java frameworks
Jun 05, 2024 pm 05:25 PM
Evaluating the cost/performance of commercial support for a Java framework involves the following steps: Determine the required level of assurance and service level agreement (SLA) guarantees. The experience and expertise of the research support team. Consider additional services such as upgrades, troubleshooting, and performance optimization. Weigh business support costs against risk mitigation and increased efficiency.
How does the learning curve of PHP frameworks compare to other language frameworks?
Jun 06, 2024 pm 12:41 PM
The learning curve of a PHP framework depends on language proficiency, framework complexity, documentation quality, and community support. The learning curve of PHP frameworks is higher when compared to Python frameworks and lower when compared to Ruby frameworks. Compared to Java frameworks, PHP frameworks have a moderate learning curve but a shorter time to get started.
How do the lightweight options of PHP frameworks affect application performance?
Jun 06, 2024 am 10:53 AM
The lightweight PHP framework improves application performance through small size and low resource consumption. Its features include: small size, fast startup, low memory usage, improved response speed and throughput, and reduced resource consumption. Practical case: SlimFramework creates REST API, only 500KB, high responsiveness and high throughput
Performance comparison of Java frameworks
Jun 04, 2024 pm 03:56 PM
According to benchmarks, for small, high-performance applications, Quarkus (fast startup, low memory) or Micronaut (TechEmpower excellent) are ideal choices. SpringBoot is suitable for large, full-stack applications, but has slightly slower startup times and memory usage.
Golang framework documentation best practices
Jun 04, 2024 pm 05:00 PM
Writing clear and comprehensive documentation is crucial for the Golang framework. Best practices include following an established documentation style, such as Google's Go Coding Style Guide. Use a clear organizational structure, including headings, subheadings, and lists, and provide navigation. Provides comprehensive and accurate information, including getting started guides, API references, and concepts. Use code examples to illustrate concepts and usage. Keep documentation updated, track changes and document new features. Provide support and community resources such as GitHub issues and forums. Create practical examples, such as API documentation.
How to choose the best golang framework for different application scenarios
Jun 05, 2024 pm 04:05 PM
Choose the best Go framework based on application scenarios: consider application type, language features, performance requirements, and ecosystem. Common Go frameworks: Gin (Web application), Echo (Web service), Fiber (high throughput), gorm (ORM), fasthttp (speed). Practical case: building REST API (Fiber) and interacting with the database (gorm). Choose a framework: choose fasthttp for key performance, Gin/Echo for flexible web applications, and gorm for database interaction.
Detailed practical explanation of golang framework development: Questions and Answers
Jun 06, 2024 am 10:57 AM
In Go framework development, common challenges and their solutions are: Error handling: Use the errors package for management, and use middleware to centrally handle errors. Authentication and authorization: Integrate third-party libraries and create custom middleware to check credentials. Concurrency processing: Use goroutines, mutexes, and channels to control resource access. Unit testing: Use gotest packages, mocks, and stubs for isolation, and code coverage tools to ensure sufficiency. Deployment and monitoring: Use Docker containers to package deployments, set up data backups, and track performance and errors with logging and monitoring tools.
What are the common misunderstandings in the learning process of Golang framework?
Jun 05, 2024 pm 09:59 PM
There are five misunderstandings in Go framework learning: over-reliance on the framework and limited flexibility. If you don’t follow the framework conventions, the code will be difficult to maintain. Using outdated libraries can cause security and compatibility issues. Excessive use of packages obfuscates code structure. Ignoring error handling leads to unexpected behavior and crashes.
