Creating a Web API in ASP. NET Core. WEBINAR On demand webcast. How to Boost Database Development Productivity on Linux, Docker, and Kubernetes with Microsoft SQL Server 2. REGISTER RESTful services are quite common and popular these days. If you ever developed modern service based applications using ASP. NET Web Forms and ASP. NET MVC, chances are you used a Web API to create REST services. MDGx AXCEL216 MAX Speed Performance Windows 10 2012 8. Vista 2003 XP SP1 SP2 SP3 ME 2000 98 SE OSR2 OSR1 95 NT4 NT 3. DOS 6 Tricks Secrets Tips. No wonder ASP. NET Core also allows you to create a Web API. This article discusses how a Web API service can be created in ASP. NET Core. It then shows how the created service can be invoked from Java. Script code. Creating the Employee service. Lets create a Web API service that performs CRUD Create, Read, Update, and Delete operations on the Employees table of the Northwind database. To begin, create a new ASP. NET Core Web application using Visual Studio 2. Figure 1. Figure 1 Creating a new ASP. NET Core Web application. Pick Web API as the project template in the next dialog, shown in Figure 2. Figure 2 Choosing the project template. This way, you will get the default configuration and Web API controller that you can modify to suit your needs. When you create the project, open Values. Controller. cs from the Controllers folder. You should see something like this namespace Web. APIIn. Asp. Net. Core. Controllers. Routeapicontroller. Values. Controller Controller.

Controller base class. In ASP. NET Core, the Web API has been merged with MVC therefore, both the controllersthe MVC controller as well as the Web API controllersinherit from the Controller base class. Because Web API is now just another controller, you can have as many actions you want. Of course, to create a REST style service, you still need to have those standard Get, Post, Put, and Delete actions as before.

Get, Http. Post, Http. Put, and Http. Delete. The Internet Explorer Web Controls Packages From Santa' title='The Internet Explorer Web Controls Packages From Santa' />This is different than before, where HTTP verbs were automatically mapped with the actions by default. The Values. Controller class also has a Route attribute that decides how the service will be accessed. By default, the service URL takes the form apivalues, but you can change the route as needed. Okay. Rename the Values. Controller both the class and the. Employee. Controller and save the file. You will revisit Employee. Controller after creating the Entity Framework Core model required by the application. Next, you need to add Entity Framework Core to your project. To do so, right click the Dependencies folder in the Solution Explorer, and select the Manage Nu. Get Packages option. Then, add the Entity. Framework. Core. Sql. Server Nu. Get package. After doing this step, you should see the required packages added to your project see Figure 3. Figure 3 Adding the Entity. Framework. Core. Sql. Server Nu. Get package. Then, open the Startup class and add EF Core to the services collection. The following code shows how this is done public void Configure. ServicesIService. Collection services. Add framework services. Add. Mvc. services. Add. Entity. Framework. Sql. Server. Configure. Services calls Add. Entity. Framework. Sql. Server to add EF Core to the list of services. Although we are not configuring the Db. Context here for DI, you could have done so if needed. For the sake of simplicity, we will specify the connection string in the Db. Context class itself. Also, modify the Configure method to set up the default MVC route as shown below public void ConfigureIApplication. Builder app. IHosting. Environment env, ILogger. Factory logger. Factory. Candidate Selection Matrix Template on this page. Factory. Add. ConsoleConfiguration. Get. Section. Logging. Factory. Add. Debug. Use. Mvc. With. Default. Route. Here, we call the Use. Mvc. With. Default. Route method to configure the default route controlleractionid for MVC requests. We do this because later we will develop a Java. Script client that invokes the Web API. And, we will need an MVC controller. Now, you can create the EF Core model needed by the application. To do so, add a Models folder you could have placed these classes in some other folder, also and add two classes to itEmployee and Northwind. Db. Context. The following code shows what Employee class looks like. System. using System. Collections. Generic. System. Linq. using System. Threading. Tasks. System. Component. Model. Data. Annotations. System.

ID get set. Required. public string First. Name get set. Required. Last. Name get set. Required. public string City get set. The Employee class is mapped to the Employees table using the Table data annotation attribute. It has four properties Employee. ID, First. Name, Last. Name, and City. The Employee. ID property also is marked using the Database. Generated attribute because its an identity column. The Northwind. Db. Context class is shown next. System. using System. Collections. Generic. System.

Make sure to change the database connection string as per your setup. Okay. So far, so good. Now, open the Employee. Controller and write the following code in it. System. using System. Collections.
