.NET Core vs .NET Framework: How to Pick a .NET Runtime for an Application

.NET Framework class library

.NET Framework
Interoperability between managed and unmanaged code enables developers to continue to use necessary COM components and DLLs. Xamarin shares code across platforms and uses a single technology stack to decrease time to market and engineering costs. Thank You for Submitting Your Review,! This means that managed code can consume other managed types and instances, while strictly enforcing type fidelity and type safety. These class libraries implement many common functions, such as file reading and writing, graphic rendering, database interaction, and XML document manipulation.

This infrastructure enables you to use managed code to write your business logic, while still enjoying the superior performance of the industry's best enterprise servers that support runtime hosting. NET Framework class library is a collection of reusable types that tightly integrate with the common language runtime. The class library is object oriented, providing types from which your own managed code derives functionality. This not only makes the. NET Framework types easy to use but also reduces the time associated with learning new features of the.

In addition, third-party components integrate seamlessly with classes in the. NET Framework collection classes implement a set of interfaces for developing your own collection classes. Your collection classes blend seamlessly with the classes in the. As you would expect from an object-oriented class library, the. NET Framework types enable you to accomplish a range of common programming tasks, including tasks such as string management, data collection, database connectivity, and file access.

In addition to these common tasks, the class library includes types that support a variety of specialized development scenarios. NET Framework to develop the following types of apps and services:. See Building Console Applications. See Windows Presentation Foundation. See Introduction to Windows Service Applications. See Building Workflows in the.

If you write an ASP. Our new feedback system is built on GitHub Issues. Read about this change in our blog post. NET Framework is designed to fulfill the following objectives: Note For a general introduction to the. We'd love to hear your thoughts.

Choose the type you'd like to provide: Can I go ahead with removal? Can I uninstall all these too, without affecting the OS? Only seems to Work on new Windows installations. It is as big as an elephant. You have to decompile and recompile in Version 3. I suppose software developers don't mind this if you bought their software. I was wrong, I mean a whale and it is slower than the slowest dog on the track. Opp's I was wrong again a turtle is faster..

Takes ages and ages to process data which should take seconds. I suppose business like paying people to sit back in the chair, waiting for their data to be processed. In the mean time buy an Iphone you need it for the wait Needed to download on Vista x64, Definitely sped up overall speed of computer on office network Updated on Apr 13, Yeah, Yeah Yeah.

These class libraries implement many common functions, such as file reading and writing, graphic rendering, database interaction, and XML document manipulation. The class libraries are available for all CLI compliant languages. The class library is divided into two parts with no clear boundary: BCL classes are available in. NET Framework as well as its alternative implementations including. NET Core and Mono.

With the introduction of alternative implementations e. With the further proliferation of. NET platforms are encouraged to implement a version of the standard library allowing them to re-use extant third-party libraries to run without new versions of them.

NET Standard Library allows an independent evolution of the library and app model layers within the. NuGet is the package manager for all. It is used to retrieve third-party libraries into a. NET project with a global library feed at NuGet. Atop the class libraries, multiple app models are used to create apps. NET Core apps by default. Other app models are offered by alternative implementations of the.

NET Core are available on. The retroactive architectural definition of app models showed up in early and was also applied to prior technologies like Windows Forms or WPF. NET decompilers such as. NET Reflector reveal only the managed code.

Because computer systems commonly require interaction between newer and older applications,. NET Framework provides means to access functions implemented in newer and older programs that execute outside. EnterpriseServices namespaces of the framework. Because of this feature,.

NET Framework supports the exchange of types and object instances between libraries and applications written using any conforming. NET Framework also enforce type safety. This prevents ill-defined casts, wrong method invocations, and memory size issues when accessing an object.

This also makes most CLI languages statically typed with or without type inference. This makes it possible for third parties to create compatible implementations of the framework and its languages on other platforms. NET Framework has its own security mechanism with two general features: CAS is based on evidence that is associated with a specific assembly. Typically the evidence is the source of the assembly whether it is installed on the local machine or has been downloaded from the Internet.

CAS uses evidence to determine the permissions granted to the code. Other code can demand that calling code be granted a specified permission. The demand causes CLR to perform a call stack walk: Managed CIL bytecode is easier to reverse-engineer than native code, unless obfuscated. NET decompiler programs enable developers with no reverse-engineering skills to view the source code behind unobfuscated.

In contrast, apps compiled to native machine code are much harder to reverse-engineer, and source code is almost never produced successfully, mainly because of compiler optimizations and lack of reflection. Labs , Turbo , and Red Gate Software. Method-level encryption tools for. NET code are available from vendors such as SafeNet. CLR frees the developer from the burden of managing memory allocating and freeing up when done ; it handles memory management itself by detecting when memory can be safely freed.

As long as a reference to an object exists, which may be either direct, or via a graph of objects, the object is considered to be in use. When no reference to an object exists, and it cannot be reached or used, it becomes garbage, eligible for collection. NET Framework includes a garbage collector GC which runs periodically, on a separate thread from the application's thread, that enumerates all the unusable objects and reclaims the memory allocated to them.

It is a non-deterministic, compacting, mark-and-sweep garbage collector. GC runs only when a set amount of memory has been used or there is enough pressure for memory on the system.

Since it is not guaranteed when the conditions to reclaim memory are reached, GC runs are non-deterministic. NET application has a set of roots, which are pointers to objects on the managed heap managed objects.

These include references to static objects and objects defined as local variables or method parameters currently in scope, and objects referred to by CPU registers. It uses CLI metadata and reflection to discover the objects encapsulated by an object, and then recursively walk them.

It then enumerates all the objects on the heap which were initially allocated contiguously using reflection. All objects not marked as reachable are garbage. However, this leaves chunks of free space between objects which were initially contiguous. The objects are then compacted together to make free space on the managed heap contiguous again. The latest version of. NET framework uses concurrent garbage collection along with user code, making pauses unnoticeable, because it is done in the background.

The garbage collector used by. NET Framework is also generational. Newly created objects are tagged Generation 0. Objects that survive one garbage collection are tagged Generation 1. Generation 1 objects that survive another collection are Generation 2. The framework uses up to Generation 2 objects. This raises the efficiency of garbage collection, as older objects tend to have longer lifetimes than newer objects.

When an application is first launched, the. NET Framework compiles the CIL code into executable code using its just-in-time compiler , and caches the executable program into the. To speed up the first launch, developers may use the Native Image Generator utility to manually ahead-of-time compile and cache any.

The garbage collector, which is integrated into the environment, can introduce unanticipated delays of execution over which the developer has little direct control. Simd namespace in In case the CPU lacks support for those extensions, the instructions are simulated in software. NET Framework is the predominant implementation of.
