Hidden Surprises in .NET 3.5 Service Pack 1

Hidden Surprises in .NET 3.5 Service Pack 1

Could not load type 'System.Web.UI.ScriptReferenceBase' from assembly 
'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, 
PublicKeyToken=31bf3856ad364e35'.

You are stymied. You've never heard of the class; you certainly don't use it in your code. You use ScriptReference, of course; who doesn't? But what's ScriptReferenceBase? Going to the documentation for ScriptReferenceBase, you learn that it is the parent class of ScriptReference and CompositeScriptReference. What? No it isn't! The documentation for ScriptReference clearly indicates that it's parent is System.Object! What's going on here?

Then you notice the Version Information for ScriptReferenceBase: "Supported in: 3.5 SP1". It's a new class for Service Pack 1. It doesn't exist in .NET 3.5 and the documentation for ScriptReference is clearly stale.

Checking Request is Synchronous or Asynchronous in ASP.NET

Checking Request is Synchronous or Asynchronous in ASP.NET

In case Asp.Net 2.0 and AJAX, when any exception thrown while execution of asynchronous request, it is catched in "ScriptManager1_AsyncPostBackError" event, then AJAX framework handles that exception and shows java script alert box to user. No event (Application_Error) from Global.asax file gets fired.

But, in Asp.Net 3.5 AJAX they changed exception handling mechanism and now both events "ScriptManager1_AsyncPostBackError" and Application_Error from Global.asax gets fired.

Issue: Now, if exception occurs in case of asynchronous request, application tries to redirect user to generic error page instead of showing JavaScript alert and ends up in another exception as Redirect is not allowed in asynchronous request. Ha.... exception within Application_Error method ;).

Speaking at Connecticut Code Camp 8/16/2008

I will be at the Connecticut Code Camp on 8/16/2008 presenting the same talk that went so well at the last Philly.net Code Camp: SRP / DI / IOC : Don't Leave Sub Main Without Them!

This talk is a very gentle introduction to:

The Single Responsibility Principle
Dependency Injection

Inversion of Control

These great tastes taste GREAT together, and I'm very passionate about "spreading th word!"

In this talk we will go over what these things ARE, and WHY you should be using them. Rather than dive into one of the existing "frameworks" such as Spring.NET, Castle, or Unity, we will build our own right there during the talk and demonstrate how it can improve your code.

Speeding Up FireFox When Using the ASP.NET Development Server from Localhost

Speeding Up FireFox When Using the ASP.NET Development Server from Localhost

The problem was I noticed that Firefox was loading pages very slowly. I'd visit a site through localhost (via the ASP.NET Development Web Server) and pages would take several seconds to load.

Firebug will show you the total number of network resources downloaded when visiting a page, along with the time it took to download each.

Each resource - from the 4KB HTML fiel to the 7KB JPG file, was taking close to a FULL second to retrieve!

I next opened Internet Explorer - the same pages loaded instantaneously.

Turns out that there is a known issue with Firefox's IPv6 support and the ASP.NET Web Development Server that introduces these lengthy delays.

Consequently, to fix this problem of slow response times when visiting localhost using Firefox, either set the network.dns.diableIPv6 configuration property to true or set the network.dns.ipv4OnlyDomains configuration property to “localhost”.

Declare Active Conventions inside C# or VB.NET Source Code

clipper's remarks: NDepend is awesome

Clip Source: codebetter.com

Declare Active Conventions inside C# or VB.NET Source Code

With the last version of NDepend, we polished one particular scenario that I would like to describe properly: The possibility to store CQL rules inside source code.

Consider this piece of code:

let's write a custom convention that checks that:

When a method is calling the method Foo1(), it must also call the method Foo2(int).

Right click the editor and select: Copy to clipboard to insert this query in C# source code ...

... and paste the clipboard content just before the Fct1() method definition. An attribute is now tagging the Fct1() method definition.

It makes sense to declare such constraint near the Foo1() / Foo2(int) methods definitions. This way, during code review or refactoring developers cannot miss it. This is active documentation.

ZipFS: Using ZIP files as virtual directories

clipper's remarks: not actual IIS virtual directories, mind you... much cooler than that

Clip Source: www.codeproject.com

ZipFS: Using ZIP files as virtual directories or read-only resource containers in ASP.NET

In your ASP.NET application, you may have a set of static files and directories with many image, script, resource files in them. Especially extensive javascript libraries with plugin support (like TinyMCE) may have hundreds of files on their own. You probably never modify any of these files, unless you upgrade to a newer version of those libraries.

And here comes my solution proposal: Why not keep these libraries (or other resources) in a zip file of their own (as most of them already distributed as zip files) and use them as if that ZIP file is a virtual directory on ASP.NET server? (note: "virtual directory" here is not related to IIS virtual directories)

Clip Source: weblogs.sqlteam.com

SRP / DI / IOC : Don't Leave Sub Main Without Them

I'll be giving a talk at the Philly.NET Code Camp on 5/17/2008.

The Single Responsibility Principle. Dependency Injection. Inversion of Control.

If you don't already know and apply these concepts in your day-to-day development this talk is for you.

The talk will present a very easy learning curve into these topics. We will cover the "why" as well as the "how." We will take a simple application written without these techniques and transform it step-by-step.

While we will see that these things make testing your code much easier, we will also see that their use goes far beyond testing scenarios.

In order to better communicate the "how" , we will not be using any pre-existing IOC framework such as Castle, Spring.NET, StructureMap, etc. Rather, we will build our own simple implementation during the talk.

TestDriven.Net 2.13: Support for NUnit 2.4.7

The latest release of TestDriven.Net is now compiled against NUnit 2.4.7. This version of NUnit includes Andreas Schlapsi's popular RowTest extension. The RowTest attributes have been moved to the 'nunit.framework.extensions' assembly (which you can find here: \Program Files\TestDriven.NET 2.0\NUnit\2.4\nunit.core.extensions.dll).

The prime number function might look like this:

As you can see the intention of the test is very clear and there is no repetition. I've written more about parameterized unit tests here.

Lambda Expressions in 5 Minutes

Lambda Expressions in 5 Minutes

You don't need a course in advanced calculus to understand Lambda Expressions. In fact, you can learn the basics in 5 minutes or less. To accomplish this, we are going to revise a code snippet for an event handler from .Net 1.1 syntax to a syntactically sweet Lambda Expression. Before we jump to the code, let's define some basic terms for this exercise:

Delegate
A type that references a method (or a strongly-typed function pointer in c++ terms). The following variable of type EventHandler contains a reference to a method I would like run when Button1 is clicked.

Named Method
A method with a name. When Button1 is clicked, execute the following named method "Button1_ClickHandler."

Anonymous Method
A method without a name. When Button1 is clicked, execute the following statement(s): MessageBox.Show("You clicked Button1!");

Anonymous Function
An anonymous method that returns a value.

Lambda Expression
An expression syntax for an anonymous function.
