- 3. Sometime in the July 2000, Microsoft announced a whole new software development framework for Windows called .NET in the Professional Developer Conference (PDC). Microsoft started development on the .NET Framework in under the name of Next Generation Windows Services (NGWS). By late 2000 the first beta versions of .NET 1.0 were released. 1.1Historyof.Net

- 5. 1.3 Flavors of .NET Console applications: • These refer to traditional DOS kind of applications like batch scripts. •It has CUI(character based User Interface). ASP.NET/ Web applications: •These include dynamic and data driven browser based applications. Windows Form based applications: • These refer to traditional rich client applications. It has GUI (Graphical User Interface)
- 6. WPF Application (Windows Presentation Foundation): •WPF is a powerful new infrastructure based on DirectX. •This means that you can use rich graphical effects without incurring the performance overhead that you’d suffer with Windows Forms. •In fact, you even get advanced features such as support for video files and 3-D content. Xamarin: •Its Free, Open Source and Cross platform Mobile App Dev. SDK. •An app platform for building Android and iOS apps with .NET and C#.

- 10. NET CLR is a run-time environment that manages and executes the code written in any .NET programming language. •It converts code into native code which further can be executed by the CPU. •Base Class Library Support It is a class library that provides support of classes to the .NET application •Type Checker It checks types used in the application and verifies that they match to the standards provided by the CLR. •Code Manager It manages code at execution run-time. •Garbage Collector It releases the unused memory and allocates it to a new application. •Exception Handler It handles the exception at runtime to avoid application failure.
- 11. • is a set of instructions that are platform independent and are generated by the language-specific compiler from the source code. • The MSIL is platform independent and consequently, it can be executed on any of the Common Language Infrastructure supported environments such as the Windows .NET runtime.
- 12. • CLS stands for Common Language Specification and it is a subset of CTS. It defines a set of rules and restrictions that every language must follow which runs under the .NET framework. • The languages which follow these set of rules are said to be CLS Compliant. • For Example • For each. Net lang we have to use the new keyword to create an instance, index of array of each. Net lang should start with 0.
- 13. • Common Type System (CTS) describes the datatypes that can be used by managed code. CTS defines how these types are declared, used and managed in the runtime. • It facilitates cross-language integration, type safety, and high-performance code execution.
- 14. The JIT compiler translates the MSIL code of an assembly to native code and uses the CPU architecture of the target machine to execute a . NET application. • Pre-JIT: Compiles the entire source code during compilation and is used at the time of deployment. • Econo-JIT: Compiles methods that are called during run time. • Normal-JIT: Compiles only the methods called during run time (at the instant of their first call) and stores the compiled code in cache to be used in subsequent calls.

- 17. Terms .Net Fx .Net Core Open Source Proprietary Framework Open Source Framework Cross-Platform .NET Framework enabled developers to build applications for a single platform — Windows. .NET Core is cross-platform, and supports three distinct operating systems — Windows, OS X, and Linux. Installation The .NET Framework needs to be installed as a single package and runtime environment for Windows. .NET Core is cross-platform, and needs to be packaged and installed independent of the underlying operating system. Modular Collection of Libraries .NET fx is not cross-platform, and needs to be packaged and installed underlying operating system. .NET Core is cross-platform, and needs to be packaged and installed independent of the underlying operating system. Application Models The application model of .NET Framework includes Windows Forms, ASP.NET, and Windows Presentation Foundation (WPF). On the other hand, the application model of .NET Core includes ASP.NET Core and Windows Universal Apps. 1.9 .Net Fx and .Net Core
- 18. Deployment Options .NET Framework, developers have to deploy web applications only on Internet Information Server. the web applications developed with ASP.NET Core can be hosted in a number of ways. Cloud Ready Configuration Required some additional config. Unlike .NET Framework, .NET Core is designed with features to simplify development and deployment of cloud-based application. Performance and Scalability Its comparatively poor than .Net Core App in terms of performance. NET Core is more effective than .NET Framework to enhance the performance and scalability of applications. Microservices Unlike .NET Framework, .NET Core makes it easier for developers to build microservice oriented systems rapidly.
