Add a database context class

Add the following RazorPagesMovieContext class to the Data folder:
The preceding code creates a DbSet property for the entity set. In Entity Framework terminology, an entity set typically corresponds to a database table, and an entity corresponds to a row in the table. The code won't compile until dependencies are added in a later step.
Add a database connection string
Add a connection string to the appsettings.json file as shown in the following highlighted code:
::: moniker range=">= aspnetcore-3.0"
Register the database context
Add the following using statements at the top of Startup.cs:
using RazorPagesMovie.Data;
using Microsoft.EntityFrameworkCore;
Register the database context with the dependency injection container in Startup.ConfigureServices.
::: moniker-end
::: moniker range="< aspnetcore-3.0"
Add required NuGet packages
Run the following .NET Core CLI command to add SQLite and CodeGeneration.Design to the project:
dotnet add package Microsoft.EntityFrameworkCore.SQLite
dotnet add package Microsoft.VisualStudio.Web.CodeGeneration.Design
dotnet add package Microsoft.EntityFrameworkCore.Design
The Microsoft.VisualStudio.Web.CodeGeneration.Design package is required for scaffolding.
Register the database context
Add the following using statements at the top of Startup.cs:
using RazorPagesMovie.Models;
using Microsoft.EntityFrameworkCore;
Register the database context with the dependency injection container in Startup.ConfigureServices.
Build the project as a check for errors.
