Use Razor Pages, Mvc, And Web Api In A Single Asp Net Core Application

We will create the first Hello world program using Razor pages. In this article, we are going to discuss Razor pages with Core. We are going to use the latest stable version of Framework – .Net 5 for this article. That completes all the necessary work in the CustomersRepository.cs file. For a deeper explanation of these points, see the Architectural principles article on It’s well worth the investment of time, even if you just need a refresher.

This, in itself, has an interesting side effect for MVC. Entities in most MVC applications start with simple CRUD operations; however, this is typically short-lived. As more “actions” are required, controllers quickly become bloated. Each page stays focused on a single activity, which allows them to be smaller and less bloated. In my previouspost, we discussed the ASP.NET Core Model-View-Controller web application framework and what better way to start our journey through ASP.NET Core. This framework is battle-hardened and has been around since early 2009. To touch on the essential components, we reviewed everything that gets scaffolded in a new project.

Lets implement this interface with using Data layer objects. In our case Data layer represents from Entity Framework Core so we should use DataContext object. In order to use AspnetRunContext object which represent us DB Layer, the constructor should use dependency injection to inject the database context into the ProductRepository class. If you look at the Initial class you can see Up() and Down() methods which provide to prepare database scripts when database updated. So when you changed anything under the Entities folder, in order to reflect to database, first you should run add-migration command and see the changes on these migration classes. Most of the web applications following common steps when you start a new web application. Based on that we will create a basic infrastructure of crud operations on core web application in one layer.

  • Then the page is rendered for the browser using the layout in Create.cshtml.
  • Stable, but still versions with a shorter support period.
  • Add asynchronous functionality to the repositories and the page model action methods.

To store these entities, we should create a DataContext class. By this properties, EF.Core will understand to create table for this entities at database. Here’s an overview of the main project folders and files that you will work with in our operations. First, you need to add a PackageReference to the NuGet Package JetBrains.Annotations in our MVC project. In this demo, we are going to implement the ‘Code With Existing Database’ technique. Creating the classes for an existing database is known as ‘Code First With Existing Database’.

Look Ma, No More Potentially Dangerous Requests

Microsoft marks certain versions with long time support which is around 3 years, while others are versions in between. Stable, but still versions with a shorter support period. Overall, these changes require you to update the .NET Core version ASP.NET Core 3.1 Razor Lessons more often than you have been used to or accept to run on an unsupported framework version. One around issues migrating from .NET Framework to .NET Core in general. Another specifically about migrating from ASP.NET to ASP.NET Core.

ASP.NET Core 3.1 Razor Lessons

A content type is like the structure or blueprint of a page or a section of your web or mobile property. For this app, we need one content type named Product. We need this content type to add the product content for our app.

To complement this updated post in 2020, you may also refer to a previous posts in this series to learn more aboutForms and Fields. This is the eighteenth of a newseries of postson ASP .NET Core 3.1 for 2020. In this series, we’ll cover 26 topics over a span of 26 weeks from January through June 2020, titledASP .NET Core A-Z! To differentiate from the2019 series, the 2020 series will mostly focus on a growing single codebase (NetLearner!) instead of new unrelated code snippets week.

As a long-time trainer, he led many courses on these topics and spoke about them at international conferences. He also travels around the globe to offer his self-developed workshops.

Razor Pages Architecture

There are just a few preparatory steps required before you can get started. Ensure that the three files are loaded in the correct order.

Also You can see from Sql Server Object Explorer that the UnitPrice is added to the table. First, add this property to the Product entity class (Entities/Product.cs) as follows.

Import Content Type

Can work with C# programming language with Razor markup. Below are the prerequisites before we start with this article.

We can see these changes reflected in the ConfigureServices method. Furthermore, instead of using the MVC controller routing, Razor Pages are mapped with endpoint routing. As a recap, all ASP.NET Core applications use a startup class to register services and configure the HTTP request middleware. This process takes place in the ConfigureServices and Configure methods. I’ve discussed these methods previously, so I won’t go into the details here (for reference, I’ve included the links below). To implement in a clean way, we’ll leverage Extension methods.

The Page Model class contains actions that deal with HTTP verbs such as GET and POST. If you developed web applications using ASP.NET Web Forms you will find Razor Pages approach familiar. is error logging, uptime monitoring, deployment tracking, and service heartbeats for your .NET and JavaScript applications. Stop relying on your users to notify you when something is wrong or dig through hundreds of megabytes of log files spread across servers. With, we store all of your log messages, notify you through popular channels like email, Slack, and Microsoft Teams, and help you fix errors fast.

ASP.NET Core 3.1 Razor Lessons

This article explains aspnetrun basic repository of github. This series of articles continues as per difficulty levels. This article intended for the beginners of core. You can follow the other articles at the end of the page. Includes a set of predefined targets, properties, and items that allow customizing the compilation of Razor files. Hopefully, I think this article delivered some useful information on .NET6 Razor Pages CRUD Operation.

Analysis Of Template Method Design Pattern In  Net C#

There might be some tools to help with this, but I ended up migrating everything by hand. Then deleted all files in the working folder and created a new ASP.NET Core MVC project. Starting with copying in controllers, views, and models and making some global search-replace patterns to make it compile.

What You Will Learn

He also has many years of experience with .NET C# and .NET MVC. This is basically the same that you wrote in the Index.cshtml razor page but uses Employee model class rather than a PageModel class. The above code prepares the Employee model object by setting its FullName property. To complete the project setup add Scripts folder under and place jQuery library in it. Select Razor Page item and specify name as Index.cshtml. You will observe that two files – Index.cshtml and Index.cshtml.cs – get added to the Pages folder.
