Need to get rid of Microsoft Net Runtime Library IssuesAugust 24, 2020 by Luca Yagan
Over the past few weeks, some of our readers have told us they have stumbled upon the Microsoft Net Runtime Library. .NET Core 3.1
.NET Core is the cross-platform version of .NET for building websites, services, and console applications. Launching applications. Download the .NET Core runtime. Create Applications Download the .NET Core SDK. Extending all .NET Core downloads
If you've been using Windows for a long time, you've probably heard of Microsoft .NET, probably because an application asked you to install it, or because you noticed it in your list of installed programs. Unless you're a developer, you don't need a lot of knowledge to use it. It is only needed for work. But since we computer geeks love to know everything, join us to learn what .NET is and why so many applications need it.
.NET Framework Explained
The name ".NET Framework" itself is incorrect. A framework (from a programming perspective) is a set of application programming interfaces (APIs) and a shared code library that developers can call when developing applications so that they don't have to write code from scratch. In the .NET Framework, this shared code library is called the Framework Class Library (FCL). The shared library code bits can perform a wide variety of functions. Suppose a developer needs an application to be able to ping to another IP address on the network. Instead of writing this codeyourself, and then write down all the small pieces and fragments necessary to interpret the meaning of the ping results, you can use the code from the library that performs this function.
And this is just a small example. The .NET Framework contains tens of thousands of common code. This shared code makes life much easier for developers because they don't have to reinvent the wheel every time their applications need to perform a common function. Instead, they can focus on the code that is unique to their applications and the user interface that ties it all together. Using this common code structure also enables standards to be enforced between applications. It is easier for other developers to understand what a program is doing, and application users can rely on the fact that the Open and Save As dialog boxes work the same across applications.
Because .NET not only serves as a framework for shared code, it also provides a runtime environment for applications. The runtime is a stand-alone program.A large virtual machine-like environment in which applications run. Many development platforms offer the same. For example, Java and Ruby on Rails have their own runtimes. In the .NET world, the runtime is called the Common Language Runtime (CLR). When a user launches an application, the code for that application is actually compiled to machine code at runtime and then executed. The CLR also offers other services such as: CPU memory and thread management, program exception handling, and security management. The runtime is actually a way of abstracting an application from the real hardware it is running on.
There are several advantages to running applications at runtime. Most important is portability. Developers can write their code in several supported languages, including popular ones like C #, C ++, F #, Visual Basic, and dozens more. This code can then be run on any hardware that supports .NET. While the platform had to support hardware other than Windows PCs, its proprietary nature meantal that it was mainly used for Windows applications.
Microsoft has created other .NET implementations to address this issue. Mono is a free open source project that provides compatibility between .NET applications and other platforms, especially Linux. The .NET Core implementation is also a free, open source framework that allows you to deploy lightweight and modular applications across multiple platforms. .NET Core is designed to support Mac OS X, Linux, and Windows (including support for Universal Windows Platform applications).
As you can imagine, a framework like .NET can be a real boon for development. Developers can write code in their preferred language and be confident that the code can run wherever the platform is supported. Users benefit from consistent applications and the fact that many applications may not be developed at all if developers do not have access to the platform.
How Does .NET Get Into My System?
The .NET Framework has a rather complicated history, and several versions have been released over the years. TypicallyThe latest available version of .NET is included with every version of Windows. The versions need to be backward compatible (for an application written for version 2 to work with version 3 installed), but that didn't work either. Not all applications worked with newer versions. Several different versions of .NET are often installed on the same PC, especially on systems running Windows XP and Vista.
Fortunately, this is easier on modern versions of Windows. At some point in the days of Windows Vista, two important things happened. .NET Framework 3.5 was released first. This version has been redesigned to include components from versions 2 and 3. Applications that required earlier versions will now work if you only installed version 3.5. Second, updates to the .NET Framework are finally made available through Windows Update.
Together, these two things meant that developers could now be fairly confident that users already had the right components installed and that users would no longer be prompted for additional installations.
When Windows 8 was running, a new, completely redesigned version was includedthis 4 .NET Framework. Version 4 (and higher) does not provide backward compatibility with older versions. It is designed to work with version 3.5 on the same PC. Applications written before version 3.5 and below must have version 3.5 installed, and applications written before version 4 or higher must have version 4. The good news is that you, as a user, no longer need worry about these settings. Windows does almost everything for you.
Windows 8 and Windows 10 contain versions 3.5 and 4 (current version is 4.6.1). They are installed for the first time. Therefore, the first time you install an application that requires one of these versions, Windows will add it automatically. You can pre-add them to Windows if you want, by gaining access to additional Windows features. You have the option to add version 3.5 and version 4.6 separately.
However, it really doesn't make sense to add them to your Windows installation yourself unless you are developing applications. The first time you install an app that requires one of the available versions, Windows will add it for you.
What If I Have Problems With.NET?
On modern versions of Windows, you are unlikely to have any problems with .NET itself. Since both required versions are included with Windows and are installed as needed, application installation is easy. On older versions of Windows (like XP and Vista), you often had to uninstall and reinstall different versions of .NET for everything to work. They also had to go through the frameworks to make sure the correct .NET versions were installed for the applications they needed. Windows will now do it for you.
However, if you are having problems that you think are related to the .NET framework, there are several steps you can take.
First of all, make sure Windows has the latest updates. If an update is available for the .NET Framework, it might just fix your problems. You can also try uninstalling the .NET Framework versions from your computer and then re-adding them. Just read our article on adding more Windows features to see how. If none of these steps helped, you can try scanning Windows for corrupted system filesfishing. It doesn't take long and can restore system files that have been damaged or missing. Always worth a try.
If none of the above helps, download and run Microsoft .NET Framework Repair Tool. The tool supports all current versions of the .NET Framework. It will help you troubleshoot common .NET installation or update issues, and can also automatically fix any issues you may encounter.
That's all. This may be more than you ever wanted to know about the .NET Framework, but hey - the next time it appears at a party, you might surprise all your friends.

- Runtime Polymorphism And Compile Time Polymorphism In C
In the last lesson, we discussed polymorphism in Java. In this guide, we will see types of polymorphism. There are two types of polymorphism in Java: 1) Static polymorphism, also called compilation polymorphism 2) Dynamic polymorphism, also called executive polymorphism Compile-time polymorphism (or static polymorphism) The polymorphism that resolves at compile time is called static polymorphism. Method overloading is an example of compile-time polymorphism. Method overload: this allows us to have more than one method with the same name if the parameters of the methods differ in the number, order and data types of the parameters. We already talked ...
