Migrating TailspinSpyworks Web Forms to Windows Azure | Migration de l’appli Web Forms TailspinSpyworks vers Windows Azure
[アーティクル]
Windows Azure Web Sites makes it easy to create new Web Sites. A site can be empty, created from a popular framework such as Wordpress or Umbraco, or the result of a migration from an existing app.
Les sites Web Windows Azure simplifient la création de nouveaux sites Web. Un tel site peut être vide, créé à partir d’un Framework populaire tel que Wordpress ou Umbraco, ou être le résultat de la migration d’une application existante.
A lot is being written about ASP.NET MVC which is awesome, but legacy applications may still be written as ASP.NET Web Forms (Note that most of this post can also be applied to other ASP.NET apps like an MVC one!).
On écrit beaucoup à propos d’ASP.NET MVC qui est excellent, mais les applications existantes risquent fort d’être de type Web Forms ASP.NET (NB: une bonne partie de ce billet s’applique à ASP.NET en général et donc à MVC!).
Let’s see how to migrate such an ASP.NET Web Forms App. to Windows Azure Web Sites.
Voyons comment migrer une telle application ASP.NET Web Forms vers les sites Web Windows Azure.
TailspinSpyworks is one of the available samples on ASP.NET reference web site. It can be found at https://www.asp.net/web-forms/samples which leads to the following download.
TailspinSpyworks est un des exemples sur le site de référence d’ASP.NET. On peut le trouver à https://www.asp.net/web-forms/samples qui amène au site de téléchargement suivant.
The first part of this post is about downloading the sample and make it run locally. Then I’ll show how to migrate it to Windows Azure.
La première partie de ce billet est consacrée à la façon de télécharger cet exemple et le faire fonctionner localement avant de le migrer vers Windows Azure.
My development machine has Visual Studio 2012, SQL Server 2012, and the latest SQL Server Data Tools (SSDT) that can be donwloaded for Visual Studio 2012.
Ma machine de développement a Visual Studio 2012, SQL Server 2012, et les derniers outils SQL Server Data Tools (SSDT) qui peuvent être téléchargés pour Visual Studio 2012.
The solution was written with previous generation tools, but it was already targetting .NET Framework 4.0 and I won’t change that.
La solution a été écrite avec la génération précédente des outils, mais elle cible le .NET Framework 4.0 et l’on ne va pas changer cela.
After unblocking the zip file I downloaded from codeplex and unzipping to D:\dev\TailspinSpyworks-v0.9, I get the following:
Après avoir débloqué le fichier zip que j’ai téléchargé depuis codeplex et dézippé vers D:\dev\TailspinSpyworks-v0.9, j’obtiens cela:
I open the solution in Visual Studio 2012.
J’ouvre la solution dans Visual Studio 2012.
I have a simple report with just a few warnings that I can ignore.
J’'obtiens un rapport avec juste quelques warnings que je peux ignorer
The solution uses two different databases. The ASP.NET database and the commerce database. The first one contains data for ASP.NET services like membership and the commerce DB contains the core application data.
La solution utilise deux bases de données différentes. La base ASP.NET et la base Commerce. La première contient des services ASP.NET telle que les comptes et la base commerce contient les données de base de l’application.
The database connection strings suppose you have SQL Server Express. In my case, I have a SQL Server 2012 developer edition so I just move the files from App_Data in the project to the SQL Server Data folder and attach the files in that SQL Server 2012 developer edition instance. The details are beyond the scope of this post.
Les chaines de connexion des bases de données supposent l’utilisation de SQL server Express. Dans mon cas, j’ai SQL Server 2012 developer edition; je déplace donc les fichiers depuis App_Data du projet pour les attacher à cette instance SQL Server 2012 developer edition. Les détails exacts vont au delà de ce billet.

I also remove the user that corresponds to the developer as it is not used by the project. There’s an associated schema which is not used either and that can also be removed.
J’enlève également l’utilisateur qui correspond au développeur puisqu’il n’est pas utilisé dans ce projet. Il y a également un schéma associé qui n’est pas non plus utilisé et que je supprime également.
Then, it is also possible to view those databases from the SSDT; this is a way to get the connection strings, amongst other things.
Il est ensuite possible de voir ces mêmes bases de données depuis SSDT, de façon à obtenir les chaînes de connexion, entre autres.
Then the 2 local connection strings can be updated in the Web.config file. In my case, they change from
Puis les 2 chaînes de connexion locale peuvent être mises à jour dans le fichier Web.config. Dans mon cas, on les change de
I also had to fix a few things in the code like this one in D:\dev\TailspinSpyworks-v0.9\TailspinSpyworks\Error.aspx.cs
J’ai aussi dû corriger deux ou trois choses dans le code comme cela dans le fichier D:\dev\TailspinSpyworks-v0.9\TailspinSpyworks\Error.aspx.cs
…
namespace TailspinSpyworks
{
public partial class Error : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Label_ErrorFrom.Text = Request["Err"].ToString();
// there might be no Inner Exception.
//Label_ErrorMessage.Text = Request["InnerErr"].ToString();
// string.Format will apply ToString() only to non null arguments
Label_ErrorMessage.Text = string.Format("{0}", Request["InnerErr"]);
}
}
}
as well as recreate an empty event for the ProductDetails.aspx page. The event was not there and generated an exception:
ou comme recréer un évenement vide pour la page ProductDetails.aspx. L’événement était absent et générait une exception:
protected void FormView_Product_PageIndexChanging(object sender, FormViewPageEventArgs e)
{
// this event was recreated but is not handled
}
so for now, I just made the sample app working on my machine. I didn’t start the migration to Windows Azure yet! So I mark the post with an <hr/>
Donc jusqu’à présent j’ai juste fait fonctionner l’application sur ma machine. Je n’ai pas encore commencé la migration vers Windows Azure! Je marque donc le billet d’un <hr/>
OK, let’s start the migration now!
OK, démarrons la migration maintenant!
First I create a new Windows Azure Web Site named TailspinSpyworks, with an associated Windows Azure SQL database. In this case, I create a database in an existing Windows Azure SQL database server, but I could also create a new server as well.
Pour commencer je crée un nouveau site Web Windows Azure appelé TailspinSpyworks, avec une base de données Windows Azure SQL Database. Ici, je crée une base dans un serveur Windows Azure SQL Database existant, mais j’aurais aussi pu créer un nouveau serveur.
A few seconds later, I have an empty web site with its associated Windows Azure SQL Database where I’ll be able to host the migrated Web Forms app.
Quelques secondes après, j’ai un site Web vide avec une base de données Windows Azure SQL Database associée où je vais pouvoir hébergée l’application migrée.
I will get and download from the portal the publishing profile of the new web site.
Je vais récupérer et télécharger depuis le portail le profil de publication du nouveau site Web.
Now, I can start publishing from Visual Studio 2012.
Maintenant, je peux démarrer une publication depuis Visual Studio 2012.
The next screen is the most important one
L’écran suivant est le plus important
I check the “remove additional files at destination” because I know my local app has the whole content and I can remove the default index page once the App is deployed.
Je sélectionne “remive additional files at destination” parce que je sais que mon application locale a tout le contenu dont j’ai besoin et je peux donc supprimer la page d’index par défaut une fois que l’application aura été déployée.
The details about this are provided in the link. I will create such a user once the App is in the cloud. So let’s move on by restarting the publishing Wizard.
Les détails sont fournis dans le lien. Je vais créer un utilisateur de l’application une fois que cette dernière sera hébergée dans Windows Azure. Avançons et redémarrons l’assistant de migration.
The “ApplicationServices” connection string has been replaced by the “DefaultConnection” connection string. As I want to use only one database for the ASP.NET Universal Providers and the Commerce DB, I select the same connection string for both cases. It happens to be the Windows Azure SQL Database that was created with the Windows Azure Web Site.
La chaîne de connexion “ApplicationServices” a été remplacée par la chaîne de connexion “DefaultConnection”. Comme je veiux utiliser uniquement une base de données pour les fournisseurs universels ASP.NET et la base Commerce, je sélectionne la même chaîne de connexion pour les deux cas. Il s’agit d’ailleurs de la base Windows Azure SQL Database qui avait été créée en même temps que le site Web Windows Azure.
For both databases, I leave the Update Database check box cleared because I use other means to migrate the databases. The ASP.NET Universal Providers will create the schema at runtime, and I will migrate the Commerce DB with a tool I like a lot because it si simple and easy to use.
Pour les deux bases de données, je laisse la case à cocher “Update Database” vierge puisque j’utilise d’autres méthodes pour migrer les bases. La base des fournisseurs universels ASP.NET créera le schéma au moment de l’exécution, et je vais migrer le base de données Commerce avec un outil que j’aime bien pour sa simplicité d’utilisation.

Let’s now migrate the database with the Windows Azure SQL Database migration Wizard that can be found at https://sqlazuremw.codeplex.com.
Migrons maintenant la base de données avec l’assistant de migration Widnows Azure SQL Database qui peut être trouvé à https://sqlazuremw.codeplex.com.
I just download it, unblock it, and extract it to a folder from where I start SQLAzureMW.exe.
Je le télécharge, le débloque, l’extrais dans un dossier où je peux démarrer SQLAzureMW.exe.

In this case, what the tool did was to make some indexes on primary keys clustered because a Windows Azure SQL Database requires each table to have a cluster index. The tool also removed extended properties(without mentionning) that are used by the entity framework to store designer related data that can be used at design time.
Dans ce cas, ce que l’outil a fait est de rendre l’index sur la clef primaire clusterisé parce qu’une base Windows Azure SQL Database a besoin d’un index custerisé. L’outil a également supprimé des propriétés étendues (sans le mentionner) qui sont utilisées par l’entity framework pour stocker des informations du designer qui peuvent être utilisées au moment de la conception.
If you need to have a deep control on how the database is migrated, you can also use the SQL Server Data Tools (SSDT). This blog post explains how this works.
Si vous avez besoin d’avoir un contrôle plus précis sur la façon dont la migration de la base se fait, vous pouvez utiliser les SQL Server Data Tools (SSDT). Ce billet explique comment cela marche.

The script had remaining errors. So I change the local database with SSDT before re-executing the Wizard.

The tables that had already succeeded have primary key violations when trying again, which can be safely ignored. Another option could be to remove objects in the target database and retry. I choose to skip the errors.
Les tables qui avaient jusqu’ici déjà été migrées ont des violations de clef primaire quand l’outil cherche à recharger leurs données; cela peut donc être ignoré. Une autre option aurait été de supprimer les objets dans la base cible et de recommencer. Je choisis d’ignorer les erreurs en question.
