Execute code when starting an ASP.NET MVC 4 Application

Question

I want when my application starts, to execute some code

   if (!WebMatrix.WebData.WebSecurity.Initialized){
           WebMatrix.WebData.WebSecurity.InitializeDatabaseConnection("DefaultConnection", "UserProfile", "UserId", "UserName", autoCreateTables: true);

There is a folder App_start at the project, but I didn't find any file that I can add this code. Do you know if there is a specific file that has this purpose?

Have you tried the Application_Start method of Global.asax.cs? — anar khalilov

Put your code in static method inside a class.

public static class SomeStartupClass
{
    public static void Init()
    {
        // whatever code you need
    }
}

Save that in App_Start. Now add it to Global.asax, along with the other code MVC initialises here:

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();

    WebApiConfig.Register(GlobalConfiguration.Configuration);
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
    RouteConfig.RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);
    AuthConfig.RegisterAuth();

    SomeStartupClass.Init();
}

Now your startup code is separated nicely.

I've faced with the next problem: Startup's Configuration method executes every time, when user sends request to Web application (call controller's method). But I need to execute my method just only once, when I start application

This kind of startup code typically goes in the Application_Start() method, Global.asax.cs file

Use the following in the Global.asax:

protected void Application_Start(object sender, EventArgs e)
{
