Introduction to Workflow Services (building WCF Services with WF)

One of my favorite features in .NET 3.5 is the integration work that has been done between WF (Windows Workflow Foundation) and WCF (Windows Communication Foundation). Check out a c9 video with that team here. This short screencasts walks through how to consume a WCF service from a workflow, as well as implementing a service as a workflow.
This is a recording of the “first demo” I do in any of my presentations introducing this topic, and as such, it involves starting with a blank solution and building all the pieces we need.

Coding Horror: Microsoft LogParser
http://www.codinghorror.com/blog/archives/000369.html

I siti che state sviluppando funzionano perfettamente in locale e dopo un deploy danno eccezioni di sicurezza dopo il deploy?

Molti hoster stanno adottando le guidelines di Microsoft per l’hosting di applicazioni asp.net 2.0, portando il trust a livello di esecuzione a medium.

Il Medium trust è utile per eseguire più applicazioni in maniera isolata e, utilizzando il code access security, molte funzionalità del framework vanno abilitare esplicitamente nel .config creando specifici trust.

Nhibernate, alla base di Cuyhahoga, “soffre” di questo limite. Dalla versione 1.2 il problema è stato risolto. Il responsabile è log4net che “potenzialmente” scrive files di log su file system.

Cuyahoga è un framework open source scritto in C# per la creazione di siti web, basato su NHibernate.

Con la versione 1.5.0 finalmente c’è il supporto ufficiale a .net 2.0. 

E’ una versione intermedia che include il supporto al Castle IoC container per rendere cuyahoga estensibile e flessibile.

Io uso Cuyhaoga da un paio d’anni, perchè è semplice, efficente e completo (non ho bisogno di migliaia di moduli alla DNN, visto che devo svilupparli per i progetti ).

Ultimamente sono diventato un fan degli Object Relational Mappers, in particolare di ORMapper di Paul Wilson e di NHibernate.

All’inizio ero scettico, titubante per paura di aggiungere complessità alle mie applicazioni (avete presente la Enterprise Library?); poi ho dato un consiglio “spassionato” ad un collega che mi ha trascinato con il suo entusiasmo.

Clemens Vasters, “Community Relations Program Manager for the Windows Communication Foundation at Microsoft Corporation”, ritorna sull’argomento riportanto anche buoni argomenti. I soliti di chi non scrive codice e quindi non ne ha capito i vantaggi.

Proper data management is the key to great architecture. Ignoring this and abstracting data access and data management away just to have a convenient programming model is … problematic.

[...]

Many of the proponents of O/R mapping that I run into (and that is a generalization and I am not trying to offend anyone – just an observation) are folks who don’t know SQL and RDBMS technology in any reasonable depth and/or often have no interest in doing so.

Sono felicissimo di non scrivere più codice SQL, confonderlo con il codice dell’applicazione (senza arrivare a scrivere la logica nelle store procedures, che avete capito?), cambiare continuamente focus da uno strumento all’altro, da un linguaggio all’altro. E’ anche più facile da trasmettere al team l’accesso ai dati: non devono più occuparsene.

I puristi come Clemens hanno ragione nel dire che si rischia di dimenticare il database (valore principale e forse scopo dell’applicazione) ma chi usa un O/R Mapper sa qual’è la fatica e la mole di codice da scrivere ogni volta per l’accesso al database.

Another argument I keep hearing is that O/R mapping yields a significant productivity boost. However, if that were the case and if using O/R mapping would shorten the average development cost in a departmental development project by – say – a quarter or more, O/R mapping would likely have taken over the world by now.

Sono diventato molto più produttivo. Ora ho solo collection con cui fare databinding, non converto più da un tipo all’altro e mi son scordato dei Datasets.

Certo ho impiegato un po’ di tempo per il setup dell’ambiente (configurazione e data mapping): ma alla lunga ne ho risparmiato di tempo e codice. Provate a contare le righe del vostro codice dedicate al binding con i vostri oggetti di business.. Ora li ho eliminati!

Una volta c’era l’OleDb con cui si poteva ragionevolmente adattare la propria applicazione ad un database diverso da quello per cui era stata sviluppata, a scapito delle prestazioni: forse per questo son nati i provider nativi. (ok, nel tempo anche l’Enterprise Library ha implementato un factory pattern per lo scopo).

Con il Wilson ORMapper ho cambiato al volo il database e la mia applicazione non ha fatto una piega (per la cronaca, da sql server a db2): non è certo la normalità, ma a volte risulta utile.

Prestazioni? Paul Wilson ha dimostrato in passato che per molte operazioni surclassa il caricamento di un Dataset e personalmente non ho mai dovuto ottimizzare l’accesso ai dati.

Solo per condividere le mie esperienze, non devo vendervi nulla!

Se avete scritto un Data Access Layer che funziona benissimo, buon per voi! Ma guardatevi un O/R Mapper, magari open source. Sarà un’occasione per migliorare il vostro DAL o migliorare il vostro metodo di lavoro.

Usare l’oggetto XMLHttpRequest per sottoporre informazioni al server crea sicuramente un altra strada da valutare dal punto di vista della sicurezza.

In Asp.net per esempio si esce dal modello del postback a cui ci siamo dovuti abituare.

In una intervista, Eric Pascarello (autore di “Ajax in Action”) disserta sui problemi ancora non risolti della vulnerabilità del javascript:

People say this is so horrible that someone can take over this request so easily. But these people need to realize that the XMLHttpRequest is nothing more than a normal form submission. You can picture it as a form being submitted in another frame. Act like there are form tags and hidden text fields on the page. With a view source of any normal HTML form, we can grab the element names and see the parameters being sent to the server. We can look at the action attribute and see where we are submitting the data. So just like how we can see the XMLHttpRequest object, we can see the same thing on any Web page.

Pascarello: Ajax does bring in a new threat to security that a developer may not realize

Pascarello’s Rules of Thumb for Ajax Security:

1. If you use user authentication, make sure you check for it on the request page!
2. Check for SQL injections.
3. Check for JavaScript injections.
4. Keep the business logic on the server!
5. Don’t assume every request is real!
6. Check the data with validation!
7. Look at the request’s header information and make sure it is correct.

Se poi aggiungiamo che creare siti con Ajax creaiamo siti non accessibili..
