ASP.NET Core MVC SQLite

ASP.NET Core is a cross-platform, high-performance, open-source framework for building modern web applications. ASP.NET Core MVC is a model-view-controller (MVC) framework for building web applications using ASP.NET Core. It provides a clear separation of concerns between the UI and business logic, and makes it easier to test and maintain your code.

SQLite is a self-contained, serverless, zero-configuration, transactional SQL database engine. It is a popular choice for applications that need a lightweight, embedded database engine that does not require a separate server process.

To use SQLite with an ASP.NET Core MVC application, you will need to install the necessary NuGet package and configure the database connection in your application. Here is an example of how to do this:

1. Install the Microsoft.EntityFrameworkCore.Sqlite NuGet package. This package provides Entity Framework Core support for SQLite.

dotnet add package Microsoft.EntityFrameworkCore.Sqlite

2. Create a model class that represents the data you want to store in the database. For example:

public class Blog
{
    public int BlogId { get; set; }
    public string Url { get; set; }
}

3. Create a DbContext class that represents the Entity Framework context. The DbContext class is responsible for interacting with the database and managing the entities in your model.

public class BloggingContext : DbContext
{
    public DbSet<Blog> Blogs { get; set; }

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        optionsBuilder.UseSqlite("Filename=./blog.db");
    }
}

4. In your MVC controller, you can use the DbContext class to query and save data to the database. For example:

public class BlogsController : Controller
{
    private readonly BloggingContext _context;

    public BlogsController(BloggingContext context)
    {
        _context = context;
    }

    public async Task<IActionResult> Index()
    {
        return View(await _context.Blogs.ToListAsync());
    }
}

That’s a basic example of how to use SQLite with ASP.NET Core MVC. You can find more detailed information in the ASP.NET Core documentation and the Entity Framework Core documentation.
