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 ;).

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”.

ZipFS: Using ZIP files as virtual directories

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

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)

ASP.NET 2.0: Use VB.NET and C# within the App_Code folder

ASP.NET 2.0: Use VB.NET and C# within the App_Code folder

There is a way to partition the App_Code folder into sub-folders, one for each set of code files written in the same programming language. Awesome, I didn't have to spend a couple hours converting code from VB.NET to C#!

Even if you don't use multiple different programming languages for your code files in the App_Code folder, you could use this feature to organize your sets of related code files into sub-folders.

Getting data into Second Life using .NET

Getting data into Second Life using .NET

I've been having fun getting objects in Second Life talking to a database on my dev server using .NET code, so I thought I'd share the magic with those of you who are interested.

For the SecondLife bit, I'll use the llHTTPRequest object to request data from my external source. The real-world bit is some ASP.NET code running on a development server. In order to understand how this code works, you need to understand the underlying structure of a HTTP request. If you've not done anything like this before, here's a quick dive in.

Intellisense for jQuery in Visual Studio 2008

Intellisense for jQuery in Visual Studio 2008

These days I write JavaScript than C#, or at least it seems like it sometime. To make my work a little easier I have started using the JavaScript support in Visual Studio 2008 that provides Intellisense support if you put Xml Doc into your JavaScript. The problem with working with jQuery in Visual Studio 2008 is that it happens fail due to how the jQuery script is written. For reasons why Intellisense fails, you can read more from Jeff King. Adjusting jQuery to make Visual Studio happy is not really a priority and not even necessary. I can simply reference the real jQuery script from the web pages and within my scripts I can reference a stub for jQuery that is simply a shell with Xml Doc.

I copied the documentation right from the jQuery website and put it all into the following stub named jquery.intellisense.js, shown below:

Response.Redirect into a new window (with Extension Methods)

Response.Redirect into a new window (with Extension Methods)

This question comes up from time to time, to time. If you understand how redirects work, then you also know it is "not possible" to redirect into a new window, because a redirect on the server causes a special HTTP response to be sent to the users browser, the client. The browsers native implementation interprets the special response code and sends the user off to the destination. There's no built-in mechanism or standard for specifying a new window.

The only way to open a new window is for it to be initiated on the client side, whether it be through script or clicking on a link.

So the solution always proposed to this problem is to instead write out some script that opens the window, rather than using Response.Redirect:

<script type="text/javascript">

    window.open("foo.aspx");

</script>

Dissecting ASP.NET Version 3.5's Web.config File

If you've had a chance to check out Visual Studio 2008, you may have noticed that it creates a rather verbose Web.config file with a bevy of configuration elements not found in the more terse Web.config file created by Visual Studio 2005. Likewise, when opening an existing Visual Studio 2005 project in Visual Studio 2008, you are prompted with a dialog box asking if you want to upgrade the website to use .NET Framework version 3.5. If you click Yes, Visual Studio updates the application's Web.config file to include the additional markup.

In this article we will examine each of the additional configuration elements added by Visual Studio 2008 to ASP.NET 3.5 applications. Read on to learn more!

VS.NET Starter Kit for Facebook.NET Apps

VS.NET starter kit for Nikhil Kothari's Facebook.NET

Back in July Nikhil Kothari released Facebook.NET which is an ASP.NET wrapping of the Facebook API. Facebook.NET is a bit different approach than Facebook Developer’s Toolkit and provides some ASP.NET controls that wrap some of the more useful elements of the FB API. Nikhil and I exchanged a few emails back in July and he asked if I’d put this together but I’d just started a new job and was in the midst of remodeling my house and now things have settled down I decided to get it out.

Use of this starter kit is very close to the previous one I released. The kit includes a Welcome.htm which is displayed in VS.NET when you create a new application that has all of the details of getting the two flavors of FB application (IFrame and FBML) up and running. One note, I tweaked the FB API version in FBML\Default.aspx since "0.3" is no longer supported.

Let me know if you have any problems. Download
