Configuring an MVC Project to reuse Migrated Applications

In this article we'll explain how to configure an MVC project to work with a migrated project.

Add a new MVC project

1. Choose - add new project, and select ASP.NET Web Application (.NET Framework)

2. In the next wizard page, select the Empty template, and check the box next to MVC. You can also check the boxes next to Web.API and Web Forms if you want to use these technologies as well.

we choose the Empty template, because all other templates contain demo code that we don't need.

Required References

Add references to the following:

1. Firefly.Box.DLL
2. ENV
3. Your project (Northwind)
4. Your base project (NorthwindBase)

Configuring the project

1. Copy the ini file to the web application project.
2. Make the following changes to the global.asax.cs file

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Optimization;
using System.Web.Routing;
using ENV;
using ENV.Data.DataProvider;

namespace NorthwindMVC
{
    public class MvcApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles);

            //additions related to the migrated code
            Common.SuppressDialogs();
            UserSettings.DoNotDisplayUI = true;

             ConnectionManager.UseConnectionPool = true;

             //sets the current directory to the web folder directory
             Environment.CurrentDirectory = HttpContext.Current.Server.MapPath("");
             
             // Call the init of the original application to load it's ini and other settings
             Northwind.Program.Init(new string[0]);
        }
         [ThreadStatic]
         static IDisposable _profilerContext;
         protected void Application_BeginRequest(object sender, EventArgs e)
         {
             // will cause any uicontroller that is called to exit.
             Firefly.Box.Context.Current.SetNonUIThread();
             // enabled profiler for every request.
             _profilerContext = ENV.Utilities.Profiler.StartContextAndSaveOnEnd(() => ENV.ProgramCollection.CollectRequestPArametersForProfiler(), () => VirtualPathUtility.MakeRelative("~", Request.Url.AbsolutePath).Replace("/", "_") + "_" + Firefly.Box.Date.Now.ToString("YYYYMMDD") + "_" + UserMethods.Instance.mTime().ToString());
         }
         protected void Application_EndRequest(object sender, EventArgs e)
         {
             // close the profiler context if exists
             if (_profilerContext != null)
             {
                 _profilerContext.Dispose();
                 _profilerContext = null;
             }
             // release all resources, including connections etc...
             Firefly.Box.Context.Current.Dispose();
         }
    }
} 

Important note

When calling a migrated controller from a web project please remember that the ApplicationCore class's OnStart method is called before each request, and the OnEnd method is called after each request.

We recommend that you adjust these method to run as little code as possible for performance considerations.
