In the last article of learning Entity Framework, we learned about the code-first approach and code-first migrations. In this article, we’ll learn how to perform CRUD operations with ASP.NET Web API2 and Entity Framework. We’ll go step by step in the form of a tutorial to set up a basic Web API project and we’ll use the code-first approach of Entity Framework to generate the database and perform CRUD operations. If you are new to Entity Framework, follow my previous articles explaining data access approaches with Entity Framework. The article would be less of a theory and more practical so that we get to know how to set up a Web API project using Entity Framework and perform CRUD operations. We’ll not create a client for this application but rather use Postman; i.e., the tool to test the REST endpoints.

The intent of this article is to explain the code first approach and code first migrations that Microsoft’s Entity Framework provides. In my last article, I explained the theory behind the Entity Framework and the other two approaches, i.e., database first and model first approach. We’ll go step by step to explore the code first approach via which we can access the database and data using Entity Framework in our application. I’ll use Entity Framework version 6.2 and .NET Framework 4.6. and Visual Studio 2017 for the tutorial. For the database, we would be using SQL Server. You can make use of local database if do not have SQL Server installed.

The intent of this article is to explain the three data access approaches that Microsoft’s Entity Framework provides. There are several good articles on the internet on this topic but I would like to cover this topic in a more detailed way and in the form of a tutorial that would be a primer for someone who is starting to learn Entity Framework and its approaches. We’ll go step by step to explore each approach via which we can access the database and data using EF in our application. I’ll use Entity Framework version 6.2, .NET 4.6, and Visual Studio 2017 for the tutorial. For the database, we would be using SQL Server. You can make use of a local DB if you do not have SQL Server installed. I’ll explain the database first and model first approaches in this article; while the code first approach and code first migrations will be used in the following article.

In this book, you will learn about the basics of Entity Framework and the three data access approaches that Microsoft’s Entity Framework provides. This book covers the introduction to Entity Framework, how Entity Framework’s capabilities could be leveraged in .Net development irrespective of the type of application used, the key features of Entity Framework.

Imagine if an infrastructure which is available, and everyone can securely process transactional code and access the data that can never be tampered. All the transactions are stored in a form of a block which is very hard to manipulate or tamper once they are stored on a blockchain. This is the behavior of blockchain where you can store the data in the most trustworthy way in the scenarios where there is no trust. Blockchain obviously is not a place where you can store a large amount of data for every transaction. For e.g. you cannot store a lot of images or documents in bulk, but you can for sure store an information that can validate that your documents or images are tampered with or not. Most data stored on a blockchain is focused on transactions and states of objects, rather than the actual objects themselves.

This article will focus on creating VM, i.e., a Virtual Machine on Microsoft Azure. Microsoft Azure provides many cloud services and getting a virtual machine is one of those. One can create a virtual machine; i.e. a remote desktop machine, on the cloud and access the same with the provided credentials. Azure gives us the flexibility to choose the type of machine; i.e. client or server and the operating system and machine configuration of one’s choice. So, it gives the flexibility to create a small machine or set up a huge configuration machine based on the requirement. Each configuration and component chosen had a price that depends on how long and how much the VM is used. In this article, I’ll set a VM on Microsoft Azure step by step and this article will be more of a tutorial form.

This article will focus on setting up a custom Ethereum Blockchain on Azure. The article will be less theory and will focus more on the practical implementation of step by step setting up the Ethereum blockchain on Azure and transferring some Ethers between accounts using MetaMask. The article is for the readers who are more into development and have the background of Blockchain, Ethereum and Ether. We’ll cover theory in the next article of understanding Ethereum and Blockchain.
