The Three Most Important Parts of .NET Platform Essay Example for Free

The Three Most Important Parts of . final Platform EssayThe . NET Framework is an integral Windows component that supports building and running the next generation of exercises and XML tissue services. (MSDN) The objectives of the . NET role model include providing a consistent environment for local and remote execution, minimizing deployment and versioning conflicts, ensuring consistent performance across Windows and Web based applications, and promoting industry standard code that easily integrates with any other code. The three key split in the . NET framework that assume these assertable be? Common Language Runtime ? mean fellowship Library ? Assemblies Parts of the . NET Framework Common Language Runtime The Common Language Runtime (CLR) manages systems services such(prenominal) as memory management, code execution, compilation, and code safety verification. The CLR is at the heart of interoper capacity by providing a habitual environment for different codes to ru n. The incorporation of language features into a frequent language runtime, rather than a grumpy language, allows languages to freely interoperate within the overall . NET platform. (Sessions)The CLR provides a secure and robust environment for execution, multi-language support, simplified development and deployment. To provide the required functionality, the CLR provides cross-language integrating, cross-language exception handling, support for different versions, deployment support, and debugging and profiling services. (MSDN) One of the major strides that has been made with the creation of the . NET platform is the feature of language in accountence. This means that any . NET-enabled language can be handling to create code, and can be integrated with other parts of the program.This functionality is achieved by . NET through the use of an Intermediate Language into which all source codes are converted to provide a common nucleotide for execution. The CLR employs a Just-In -Time compilation (JIT) operate that includes only those parts of the code that are required at runtime to be compiled. The JIT includes a feature of caching that allows it to re-use code that is apply more than once within a program, making the process faster and more efficient. (Evjen et al. 8) The CLR uses metadata that keeps track of the types, members and references within the code.All common runtime executable versions rent the metadata, which tells the program where to brass for classes and helps if to manage memory, enforce security and generate native code. The CLR makes it possible to share classes and methods across languages, using a common type system that is delimitate during runtime. (Evjen et al. 9) The metadata enables the code to run as managed code, which runs under the CLR following(a) the rules set by it. This ensures that the services mentioned earlier such as code-access security, lifetime control of objects and memory management, and cross-language inte gration of code can be provided by the CLR.From the above it can be seen that the Common Language Runtime is rudimentary to some of the major breakthroughs in the . NET environment, and is therefore, a very important part of it. Base consort Library The second major part of the . NET framework is the Base curriculum Library. The Base Class Library contains classes and types that expedite the development process, as well as allow the sharing of these, to provide slowly and common means for accessing system functionality, and execute common tasks. The . NET types conform to Common Language Specifications that restrain to all .NET enabled languages. This makes it possible to write code in any of these languages using these types. This represents one of the major contributions to interoperability between languages, which is at the heart of the . NET approach. Thus Base Class Library forms the second some important part of the . NET framework. The . NET framework provides a number of abstract and concrete classes that make it possible to write powerful programs in any one or a combination of the support languages. The framework also provides a rich repertoire of interfaces.The rich functionality provided by the interfaces can be used by either using an existing class that implements these interfaces and by deriving a user defined class from them, or can be implemented by creating a class that implements these interfaces. The . NET applications, controls and components depend on the type definition, which is one of the constituents of the Base Class Libraries. This enables the framework to handle various functions such as encapsulating data structures, perform I/O and invoke security checks. (MSDN)From the above it can be seen that untold of the functionality of the . NET framework is derived from, and is dependent on, the Base Class Libraries. Assemblies As we have seen, the Common Language Runtime and the Base Class Libraries represent the bases on which th e crucial and differentiating features of the . NET framework are built. These provide a common framework for developing the application. The next most important aspect of an application is to run it. This is facilitated by Assemblies. Assemblies are the building blocks of .NET Framework applications they form the fundamental unit of deployment, version control, reuse, activation scoping, and security permissions. (MSDN). The Assemblies contain resources and types that are required at runtime. The Common Language runtime is possible because of Assemblies, because they provide vital information that makes the runtime application aware of the types and other resources used. This makes it possible to run an integrated application that contains diverse codes written in a variety of CLR-enabled languages.The Assembly contains code that the common language runtime executes. The Intermediate Language code depends on associated assemblies to be executed. Thus the Assemblies are fundamental to the . NET framework, and allow the parts to function at runtime. For this reason, they represent the terzetto most critical part of the . NET framework. Conclusion The . NET framework is distinguished by its ability to integrate and run code written in a variety of languages, and to operate the system firm and consistently under different environments such as remote and local execution.These features have become possible because of the three essential parts of the framework, namely the Common Language Runtime, Base Class Libraries, and Assemblies.
