Global.asax magic functions
asp.net, asp.net-mvc, c#, error-handling
Solution
It isn't really magical.. the ASP.NET Pipeline wires all of this up.
You can see the documentation regarding this here.
Specifically you will be interested in the parts below:
An `HttpApplication` object is assigned to the request.
Which consists of a list of events that are fired and in what order.
There are links all over that page (too many to contain here) that link off to various other pages with even more information.
ASP.NET automatically binds application events to handlers in the Global.asax file using the naming convention Application_event, such as `Application_BeginRequest`. This is similar to the way that ASP.NET page methods are automatically bound to events, such as the page's `Page_Load` event.

Problem
When creating an ASP.NET Mvc project in Visual Studio, a `Global.asax` & `Global.asax.cs` will be created. In this .cs file you will find the standard `Application_Start` method. My question is the following, how is this function called? because it is not a override. So my guess is that this method name is by convention. The same goes for the `Application_Error` method. I want to know where these methods are hooked. Because I write those methods (not override them) I couldn't find any documentation on them in MSDN. (I found this page but it only tells you to hook to the `Error` event and shows a `Application_Error(object sender, EventArgs e)` but not how the Event and the method are linked.) ``` //Magicly called at startup protected void Application_Start() { //Omitted } //Magicly linked with the Error event protected void Application_Error(object sender, EventArgs e) { //Omitted } ```
