To authenticate the user, you will need to set up an Okta application in your developer’s console. You simply configure your application to use the authentication service and decorate protected routes with an Authorize attribute and Okta will take care of enforcing the authorization policy as well as logging the user in. The Okta.AspNetCore package makes connecting to Okta for authentication as easy as possible. Install-Package Okta.AspNetCore -Version 3.1.1 Next, you will need to install the tools needed to connect to Okta. You will be using Version 3.1.1 for this application. You’ll see how to do that once you set up your model.įor consistency’s sake, you’ll want to make sure you specify the version across each of these tools. However, if you choose to expand this app later and need to add more complex database logic, you will need to add more migrations and apply them to your database. At the end of the article, your project will only have one Migration, InitialMigration. They can also contain logic for seeding data if necessary. Migrations can be applied and reverted, making database versioning simple. Migrations are simply a set of instructions for updating your database based on your code. Each time you update the model in your web app, you need to apply those changes to your database. Each time you update your database, you need to update the model in your web app.įor this project, you will use Code First. In Database First, you write your database and then import the structure into your project. You can decorate properties with attributes for expanded functionality-like keys-or you can use the Fluent API to define those relationships. In Code First, you will write the C# code that describes your database. They are effectively what they sound like. EF Core supports two main paradigms for integrating a database into your web application: Code First and Database First. If you’ve never used migrations before,now is a good time to say a few words about them. EntityFrameworkCore.Tools contains tools for building and deploying migrations to your database. You will also want the EntityFrameworkCore.SqlServer package as it contains some SqlServer functionality that may come in handy as your project grows. Install-Package -Version 3.1.1įor EF Core, you’ll need the core EntityFrameworkCore package. Install-Package Microsoft.EntityFrameworkCore -Version 3.1.1 For this project, you only need to add the required EF Core libraries as well as the Okta Library. Install the Entity Framework Core Nuget Packagesįirst, you’ll need to bring in any required Nuget packages for running the application. You won’t use the Privacy page so you can delete it, or hold onto it for now. The template also comes with Index.cshtml and Privacy.cshtml pages under the Home controller. The Visual Studio Web App template comes with Bootstrap and Jquery in the This is very helpful since bootstrap is one of the easiest CSS frameworks to use. Press Create and let Visual Studio scaffold your project. Uncheck Configure for HTTPS and leave Authentication as No Authentication since you will manually add it with Okta. For this application, you are using the MVC Application type rather than the new Razor Pages Application. This will bring you to the next menu where you’ll select Web Application (Model-View-Controller). You can name your project whatever you want (I named mine V_Okta), then press Create. From the next menu, search for ASP.NET Core Web Application and click Next. To start, open Visual Studio and click Create a new Project. Scaffold Your ASP.NET Core and Entity Framework Core Application You will use Visual Studio 2019, ASP.NET Core, Entity Framework Core, Microsoft SQL Server, and Okta for Authentication. To compile the list of movies the app will allow users to add, update, or delete movies from the database. In this article, you will build a small app that allows users to vote on movies. You can use it with SQLite, MySQL, PostgreSQL, and Azure Cosmos DB. EF Core also works with many different databases, not just SQL Server. EF Core supports LINQ, change tracking, and schema migrations. With the release of ASP.NET Core, Entity Framework has released its next-gen version Entity Framework Core to work with. One of the most popular tools on ASP.NET was the powerful ORM Entity Framework. Most of the new framework should be familiar to veteran ASP.NET developers however there are some new tweaks to get used to. It’s open-source which is a massive departure from Microsoft’s previous line of thinking. ASP.NET Core is cross-platform-meaning you can finally deploy your ASP.NET apps on Linux. ASP.NET Core is Microsoft’s latest iteration of its web framework, which boasts many upgrades over the.
