The Microsoft .NET Common Language Runtime provides a This paper describes the design and implementation of support shared type system, intermediate language and dynamic execution for parametric polymorphism in the CLR. In its initial release, the environment for the implementation and inter-operation of multiple CLR has no support for polymorphism, an omission shared by the source languages.

INTRODUCTION to .NET FRAMEWORK NET Framework .NET Framework Is a Complete Environment That Allows Developers to Develop, Run, An
INTRODUCTION TO .NET FRAMEWORK NET Framework .NET Framework is a complete environment that allows developers to develop, run, and deploy the following applications: Console applications Windows Forms applications Windows Presentation Foundation (WPF) applications Web applications (ASP.NET applications) Web services Windows services Service-oriented applications using Windows Communication Foundation (WCF) Workflow-enabled applications using Windows Workflow Foundation (WF) .NET Framework also enables a developer to create sharable components to be used in distributed computing architecture. NET Framework supports the object-oriented programming model for multiple languages, such as Visual Basic, Visual C#, and Visual C++. NET Framework supports multiple programming languages in a manner that allows language interoperability. This implies that each language can use the code written in some other language. The main components of .NET Framework? The following are the key components of .NET Framework: .NET Framework Class Library Common Language Runtime Dynamic Language Runtimes (DLR) Application Domains Runtime Host Common Type System Metadata and Self-Describing Components Cross-Language Interoperability .NET Framework Security Profiling Side-by-Side Execution Microsoft Intermediate Language (MSIL) The .NET Framework is shipped with compilers of all .NET programming languages to develop programs. Each .NET compiler produces an intermediate code after compiling the source code. 1 The intermediate code is common for all languages and is understandable only to .NET environment. This intermediate code is known as MSIL. IL Intermediate Language is also known as MSIL (Microsoft Intermediate Language) or CIL (Common Intermediate Language). All .NET source code is compiled to IL. IL is then converted to machine code at the point where the software is installed, or at run-time by a Just-In-Time (JIT) compiler. -
Why and How to Migrate from .NET to .NET Core. - Oliver Ray, Managing Director @ Number8
Why and How to Migrate from .NET to .NET Core. - Oliver Ray, Managing Director @ number8 There’s no time like the present when it comes to paying down technical debt, investing in high-value features, and keeping up with development house-keeping. These practices allow development velocity to skyrocket. And For most companies still utilizing .NET, migrating to .NET Core is the most impactful technical investment they can make right now. This transition will simplify your teams’ development cycles and have a measurable impact on your bottom-line. However, it can also include unforeseen complexities and dependencies, so it’s crucial that the planning and prep work is done throughly. Our team at number8 took the time to detail a few high-level benefits that every team should consider during this transition. So, let’s get started. Why migrate from .NET to .NET Core? .NET Core 1.0 was announced in 2014 and aimed to bring the .NET framework into the open source world. The ultimate goal of this initiative was to make .NET projects more portable to other platforms. With the explosion of commodity platforms like Linux and ARM64 processors, .NET had to become more open to survive. From it’s initial release .NET Core has continued to evolve to leverage a wide range of technologies that allow teams to develop systems in whatever way they see fit. A significant example of this forward thinking was early support for Docker containers and Kubernetes. Teams Start Planning everywhere are trying to rethink core enterprise Now applications to fully see the benefit of cloud tooling. -
18Mca42c .Net Programming (C#)
18MCA42C .NET PROGRAMMING (C#) Introduction to .NET Framework .NET is a software framework which is designed and developed by Microsoft. The first version of .Net framework was 1.0 which came in the year 2002. It is a virtual machine for compiling and executing programs written in different languages like C#, VB.Net etc. It is used to develop Form-based applications, Web-based applications, and Web services. There is a variety of programming languages available on the .Net platform like VB.Net and C# etc.,. It is used to build applications for Windows, phone, web etc. It provides a lot of functionalities and also supports industry standards. .NET Framework supports more than 60 programming languages in which 11 programming languages are designed and developed by Microsoft. 11 Programming Languages which are designed and developed by Microsoft are: C#.NET VB.NET C++.NET J#.NET F#.NET JSCRIPT.NET WINDOWS POWERSHELL IRON RUBY IRON PYTHON C OMEGA ASML(Abstract State Machine Language) Main Components of .NET Framework 1.Common Language Runtime(CLR): CLR is the basic and Virtual Machine component of the .NET Framework. It is the run-time environment in the .NET Framework that runs the codes and helps in making the development process easier by providing the various services such as remoting, thread management, type-safety, memory management, robustness etc.. Basically, it is responsible for managing the execution of .NET programs regardless of any .NET programming language. It also helps in the management of code, as code that targets the runtime is known as the Managed Code and code doesn’t target to runtime is known as Unmanaged code. -

Programming with Windows Forms
A P P E N D I X A ■ ■ ■ Programming with Windows Forms Since the release of the .NET platform (circa 2001), the base class libraries have included a particular API named Windows Forms, represented primarily by the System.Windows.Forms.dll assembly. The Windows Forms toolkit provides the types necessary to build desktop graphical user interfaces (GUIs), create custom controls, manage resources (e.g., string tables and icons), and perform other desktop- centric programming tasks. In addition, a separate API named GDI+ (represented by the System.Drawing.dll assembly) provides additional types that allow programmers to generate 2D graphics, interact with networked printers, and manipulate image data. The Windows Forms (and GDI+) APIs remain alive and well within the .NET 4.0 platform, and they will exist within the base class library for quite some time (arguably forever). However, Microsoft has shipped a brand new GUI toolkit called Windows Presentation Foundation (WPF) since the release of .NET 3.0. As you saw in Chapters 27-31, WPF provides a massive amount of horsepower that you can use to build bleeding-edge user interfaces, and it has become the preferred desktop API for today’s .NET graphical user interfaces. The point of this appendix, however, is to provide a tour of the traditional Windows Forms API. One reason it is helpful to understand the original programming model: you can find many existing Windows Forms applications out there that will need to be maintained for some time to come. Also, many desktop GUIs simply might not require the horsepower offered by WPF. -

Detecting Wastedlocker Ransomware Using Security Analytics
Securonix Threat Research: Detecting WastedLocker Ransomware Using Security Analytics Oleg Kolesnikov Securonix Threat Research Team Created on: July 28, 2020 Last Updated: August 18, 2020 Figure 1: Victim’s Systems Targeted by WastedLocker Unavailable (July 2020) The Securonix Threat Research Team (STR) is actively investigating the details of the critical targeted Wastedlocker ransomware attacks that reportedly already exploited more than 31 companies, with 8 of the victims being Fortune 500 companies [1], to help our customers detect, mitigate, and respond to such attacks. Here are some of the key technical details and our recommendations on possible Securonix predictive indicators/security analytics that can be used to detect the current and potentially future attack variants (these indicators may be updated as we receive more information.) 2 www.securonix.com Figure 2: WastedLocker/EvilCorp Attack in Progress - Targeting a Victim Company in a Recent High-Profile Attack Impact Here are the key details regarding the impact of the high-profile WastedLocker ransomware attacks/ EvilCorp malicious cyber threat actor(s)(MTA) involved: • The WastedLocker ransomware is a relatively new malicious payload used by the high-profile EvilCorp MTA, which previously used the Dridex trojan to deploy BitPaymer ransomware in attacks targeting government organizations and enterprises in the United States and Europe. (See Figure 1) • This MTA currently focuses on targeted “big game hunting” (BGH) ransomware attacks with multiple industry victims in recent months, with Garmin as one of the latest high-profile victims attacked (officially confirmed by Garmin on July 27). (See Figure 2) • The most recent ransom amount demanded was US$10M and appears to be based on the victim’s financial data.
