Table of contents. Here are a few common methods. You can check your installed versions of. NET by navigating to Microsoft. Each of the installed. NET versions will have its own folder. You can also check which versions of. NET are installed by looking in your registry in the following locations:. This next picture shows the second location. Note that this location shows more detail? FCL refers to the entire class library that ships with. 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.
NET architecture. NuGet is the package manager for all. NET platforms. It is used to retrieve third-party libraries into a. NET project with a global library feed at NuGet. 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. NET environment.
InteropServices and System. Enterprise Services namespaces of the framework. Access to. Interoperability enables you to preserve and take advantage of existing investments in unmanaged code.
Code that runs under the control of the common language runtime CLR is called managed code, and code that runs outside the CLR is called unmanaged code. Because of this feature,. NET Framework supports the exchange of types and object instances between libraries and applications written using any conforming. NET language. 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. However, starting with. This makes it possible for third parties to create compatible implementations of the framework and its languages on other platforms. 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 codes can demand that calling code be granted a specified permission.
The demand causes CLR to perform a call stack walk: every assembly of each method in the call stack is checked for the required permission; if any assembly is not granted the permission a security exception is thrown. 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.
NET assemblies. 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. NET since 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.
Instantiations of. 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, 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. NET application. 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 was the predominant implementation of.
NET technologies, until the release of. Other implementations for parts of the framework exist. Although the runtime engine is described by an ECMA-ISO specification, other implementations of it may be encumbered by patent issues; ISO standards may include the disclaimer, “Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
Also, parts of FCL have Windows-specific functions and behavior, so implementation on non-Windows platforms can be problematic. Microsoft managed code frameworks and their components are licensed as follows:.
