In this tutorial, we look at What is Entity Framework Migration is and how to create migrations. We will build a simple console application and create two models. We will use the add-migration command to create the migration and then use the update-database command to create the database. Next, we will update the model and create another migration and update the database. Then we will revert the migration from the database and remove the migration. Finally, we will also see how to generate SQL Scripts containing the migration commands
In this article, we look at DBContext. We also look at how to create a DBContext class in our ASP.NET Core application. Next, we will show you how to register DBContext for Dependency Injection.

In this article let us look at how to Provide Database Connection String in Entity Framework (EF) Core Applications. The DBContext connects to the database using the Database Providers. These Providers requires a connection string to connect to the database.
In this step by step tutorial, you will learn how to build the Entity Framework core console application. We will show you how to create the console application and install the required dependencies.

Next, we will use the migrations features of the Entity Framework core (EF Core) to create the database. Finally, we will show you how to perform simple tasks like insert, query, update & delete operations on the model and persist the data into the database.
This tutorial will guide you how to set up your Android phone or tablet to run NativeScript Mobile App on the real device. The Android Emulator allows us to create as many virtual devices with the different configuration to test our Apps. But it always a good idea to test our app on the actual device to check how it works.
