Create a blank ASP.NET MVC5 application.

Server side: Add references to the Vintasoft nuget-packages to ASP.NET MVC5 application.

Server side: Add Web API 2 controller, which allows to generate barcode, to ASP.NET MVC5 application.

• Press the right mouse button on the "Controllers" folder and select the "Add => Controller..." menu from context menu
  
• Select "Web API 2 Controller - Empty" template, set the controller name to the "MyVintasoftBarcodeApiController" and press the "Add" button
  
• Specify that MyVintasoftBarcodeApiController class is derived from Vintasoft.Barcode.Web.Api2Controllers.VintasoftBarcodeApi2Controller class
  
  Here are C# source codes of MyVintasoftBarcodeApiController class:
  
  • C#

  using Vintasoft.Barcode.Web.Api2Controllers;
  
  namespace WebApplication1.Controllers
  {
      public class MyVintasoftBarcodeApiController : VintasoftBarcodeApi2Controller
      {
      }
  }
  
  

• Open "App_Start\WebApiConfig.cs" file and check that ASP.NET MVC application correctly registers route for Web API controller.
  
  Here are C# source codes of WebApiConfig.cs file:
  
  • C#

  using System.Web.Http;
  
  namespace WebApplication1
  {
      public static class WebApiConfig
      {
          public static void Register(HttpConfiguration config)
          {
              config.Routes.MapHttpRoute(
                  name: "DemoAPI",
                  routeTemplate: "vintasoft/api/{controller}/{action}"
              );
          }
      }
  }
  
  

Server side: Create ASP.NET MVC 5 controller for web view that will display generated barcode.

• Press the right mouse button on the "Controllers" folder and select the "Add => Controller..." menu from context menu
  
• Select "MVC 5 Controller - Empty" template, set the controller name to the "DefaultController" and press the "Add" button
  
• Open "App_Start\RouteConfig.cs" file and check that ASP.NET MVC application correctly registers route for MVC controller.
  
  Here are C# source codes of RouteConfig.cs file:
  
  • C#

  using System.Web.Mvc;
  using System.Web.Routing;
  
  namespace WebApplication1
  {
      public class RouteConfig
      {
          public static void RegisterRoutes(RouteCollection routes)
          {
              routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
  
              routes.MapRoute(
                  name: "Default",
                  url: "{controller}/{action}",
                  defaults: new { controller = "Default", action = "Index" }
              );
  
          }
      }
  }
  
  
  

Server side: Check global configuration of ASP.NET MVC5 application.

using System.Web.Http;
using System.Web.Mvc;
using System.Web.Routing;

namespace WebApplication1
{
    public class WebApiApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();
            GlobalConfiguration.Configure(WebApiConfig.Register);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
        }
    }
}

Client side: Create web view for displaying generated barcode.

• Open "DefaultController.cs" file, press the right mouse button on the "Index" method of DefaultController class and select the "Add View..." menu from context menu
  
• Set view name to "Index", uncheck "Use a layout page" checkbox and press the "Add" button => "Views\Default\Index.cshtml" file will be created
  

Client side: Add Vintasoft JavaScript files to the project.

• Copy Vintasoft.Shared.js and Vintasoft.Barcode.js files from "<InstallPath>\VintaSoft Barcode .NET 15.3\Bin\JavaScript\" folder into "Scripts" folder.
  

Client side: Add JavaScript code, which generates and displays barcode image, to the web view.

• Open web view - file "Views\Default\Index.cshtml".
  
• Add references to Vintasoft JavaScript files:
  
  Here is HTML code that adds references to Vintasoft JavaScript files:
  
  • HTML

  <script src="~/Scripts/Vintasoft.Shared.js" type="text/javascript"></script>
  <script src="~/Scripts/Vintasoft.Barcode.js" type="text/javascript"></script>
  
  

• Add HTML markup (an image element that will display generated barcode image) to the web view:
  
  Here is HTML markup code:
  
  • HTML

  <img id="barcodeImage" src="" />
  
  

• Add JavaScript code that generates and displays barcode image:
  
  Here is JavaScript code that generates and displays barcode image:
  
  • JavaScript

  <script type="text/javascript">
      /**
       * Generates 1D barcode image.
       */
      function generate1dBarcodeImage(barcodeType, barcodeValue) {

          // send an asynchronous request for getting barcode image as Base64 string
          barcodeWriter.getBarcodeAsBase64Image(__writeBarcode_success, __writeBarcode_failed);
      }
  
      /**
       * Barcode is generated successfully.
       */
      function __writeBarcode_success(data) {
          if (data.success) {
              var barcodeImage = data.barcodeImage;
              document.getElementById("barcodeImage").src = barcodeImage;
          }
          else {
              alert(data.errorMessage);
          }
      }
  
      /**
       * Barcode generation is failed.
       */
      function __writeBarcode_failed(data) {
          // show information about error
          alert(data.errorMessage);
      }
  
  
      // set the session identifier
      Vintasoft.Shared.WebImagingEnviromentJS.set_SessionId("SessionID");
      // generate image of QR barcode with value "12345"

Run the ASP.NET MVC5 application and see the result.
