Using Web API 2 with Entity Framework 6
Software versions used in the tutorial
This tutorial uses ASP.NET Web API 2 with Entity Framework 6 to create a web application that manipulates a back-end database. Here is a screen shot of the application that you will create.
The app uses a single-page application (SPA) design. “Single-page application” is the general term for a web application that loads a single HTML page and then updates the page dynamically, instead of loading new pages. After the initial page load, the app talks with the server through AJAX requests. The AJAX requests return JSON data, which the app uses to update the UI.
Here are the main building blocks for this app:
- ASP.NET MVC creates the HTML page.
- ASP.NET Web API handles the AJAX requests and returns JSON data.
- Knockout.js data-binds the HTML elements to the JSON data.
- Entity Framework talks to the database.
See this App Running on Azure
Would you like to see the finished site running as a live web app? You can deploy a complete version of the app to your Azure account by simply clicking the following button.
You need an Azure account to deploy this solution to Azure. If you do not already have an account, you have the following options:
- Open an Azure account for free - You get credits you can use to try out paid Azure services, and even after they're used up you can keep the account and use free Azure services.
- Activate MSDN subscriber benefits - Your MSDN subscription gives you credits every month that you can use for paid Azure services.
Create the Project
Open Visual Studio. From the File menu, select New, then select Project. (Or click New Project on the Start page.)
In the New Project dialog, click Web in the left pane and ASP.NET Web Application in the middle pane. Name the project BookService and click OK.
In the New ASP.NET Project dialog, select the Web API template.
If you want to host the project in a Azure App Service, leave the Host in the cloud box checked.
Click OK to create the project.
Configure Azure Settings (Optional)
If you left the Host in Cloud option checked, Visual Studio will prompt you to sign in to Microsoft Azure
After you sign in to Azure, Visual Studio prompts you to configure the web app. Enter a name for the site, select your Azure subscription, and select a geographical region. Under Database server, select Create new server. Enter an administrator username and password.
