C# Version History

 C# is a programming language developed by Microsoft. It was first released in 2002 as part of the .NET Framework. Since then, it has undergone several updates, with the latest version being C# 9.0, which was released in November 2020.


Some of the major updates to C# include the following:


  • C# 1.0: This was the initial version of C#, which was released as part of .NET Framework 1.0 in 2002. It included features such as classes, interfaces, and garbage collection.
  • C# 2.0: This version, released in 2005, added new features such as generics, anonymous methods, and nullable types.
  • C# 3.0: This version, released in 2007, introduced important language features such as lambda expressions, extension methods, and LINQ (Language Integrated Query).
  • C# 4.0: This version, released in 2010, added support for dynamic language features, named and optional arguments, and generic covariance and contravariance.
  • C# 5.0: This version, released in 2012, added support for asynchronous programming with the async and await keywords.
  • C# 6.0: This version, released in 2015, added several new language features such as string interpolation, expression-bodied members, and the nameof operator.
  • C# 7.0: This version, released in 2017, added support for tuples, pattern matching, and local functions.
  • C# 8.0: This version, released in 2019, added support for nullable reference types, asynchronous streams, and default interface methods.
  • C# 9.0: This is the latest version of C#, which was released in November 2020. It includes features such as records, top-level statements, and improved pattern matching.


Each new version of C# has added new features and improvements to the language, making it more powerful and versatile.

Prompt Engineering Fundamentals

  Introduction Generative AI is a transformative technology capable of producing text, images, audio, and code in response to user prompts. This capability is powered by Large Language Models (LLMs) like OpenAI's GPT series, which are trained to understand and generate natural language. Interacting with these models via prompts allows users to harness their potential without needing technical expertise. This chapter explores the essentials of prompt engineering, a field dedicated to optimizing prompt design for consistent and high-quality responses. Learning Goals By the end of this lesson, you will be able to: Explain what prompt engineering is and why it matters. Describe the components of a prompt and how they are used. Learn best practices and techniques for prompt engineering. Apply learned techniques to real examples using an OpenAI endpoint. Learning Sandbox Prompt engineering is more art than science, requiring practice and iterative refinement. This lesson includes a Jupyt...

AWS Cloud Containers

Amazon Web Services (AWS) offers a variety of services for deploying and managing applications in the cloud. One of these services is called Amazon Elastic Container Service (ECS), which allows you to run and manage Docker containers on AWS. Here is a brief overview of how Amazon ECS works: You package your application into a Docker container image and push it to a registry, such as Amazon Elastic Container Registry (ECR) or Docker Hub. You create an Amazon ECS task definition, which is a blueprint for your containerized application. The task definition specifies things like the Docker image to use, the CPU and memory requirements, and the environment variables to pass to the container. You create an Amazon ECS cluster, which is a group of Amazon EC2 instances that are running the Amazon ECS container agent. The cluster is where your tasks are placed and run. You create an Amazon ECS service, which is a long-running task that is hosted on your cluster. The service ensures that a speci...

Identified COVID-19 in X-ray images with deep learning.

  Project structure :       Our coronavirus (COVID-19) chest X-ray data is in the dataset/ directory where our two classes of data are separated into covid/ and normal/   I have created train_covid19.py file to train the model.   Three command line arguments (parameters) required to run this file :   --dataset: The path to our input dataset of chest X-ray images. --plot: An optional path to an output training history plot. By default the plot is named plot.png unless otherwise specified via the command line. --model: The optional path to our output COVID-19 model; by default it will be named covid19.model.     To load our data, we grab all paths to images in in the --dataset directory. Then, for each imagePath, we:   ·           Extract the class label (either covid or normal) from the path. ·           Load the image, and preprocess it by convertin...
