Consuming Services In ASP.NET Core MVC View

In continuation of my previous article on injecting services in controller, this time I am writing on how to inject services directly in MVC View.

In order to achieve this, a new keyword @inject is used. So, let's get started.

1. Create a new project - Create a new project using ASP.NET Web Application template as in the following:
   
   
   
   
2. Add Service Interface - Create an interface named IGUIDService under Services folder as shown below:
   1. public interface IGUIDService
   2. {
   3. string GenerateGUID();
   4. }
3. Add Service Implementation - Create a class named GUIDService under Services folder and provide the implementation of IGUIDService interface as shown below:
   1. public class GUIDService : IGUIDService
   2. {
   3. public string GenerateGUID()
   4. {
   5. return ("Generated GUID is: " + Guid.NewGuid()).ToString();
   6. }
   7. }
4. Add a Controller - The next task is to add a Controller named GUIDController by right clicking on Controllers folder as shown below:
   
   
   
5. Add a View - Before adding a View, create a folder under Views folder. Now add a View by right clicking on GUID folder as shown below:
   
   Once file is added, inject service inside View as:
   1. @inject IGUIDService guidService
   Below is the complete code for displaying GUID on View:
   1. @using CustomTagHelper.Services;
   2. @inject IGUIDService guidService
   4. <p>@guidService.GenerateGUID()</p>
6. Register Service - The last step is to register the service in the ConfigureServices method of Startup class as shown below:
   1. public void ConfigureServices(IServiceCollection services)
   2. {
   3. ...
   4. ...
   5. services.AddTransient<IGUIDService,GUIDService>();
   6. }

Everything is set. Now run your application and you will be able to see GUID on browser as:



Hope you got an idea on how to inject services in MVC View in ASP.NET Core 1.0.
