On the one hand it is good to be able to do things as early in the application startup phase as possible.
On the other hand: What’s next? A PrePreApplicationStartMethod that allows you to fiddle with the PreApplicationStartMethod behaviour?

Greg Hewgill published a bunch Stack Overflow ebooks and StackExchange stats.
His readme explains a bit more on the books.
The blog he maintains makes up for some nice reading too.
Be sure to read the blog entry on the ebooks.

In Visual Studio 2010, the empty “ASP.NET Web Service Application” projects are gone.
This is probably because Microsoft rather has you use WCF, so a few of those “older” templates are now gone:
To simplify things a bit in 2010, we’ve removed a few of the older templates. You can get the same thing by creating an empty website and adding a web service to it.
Funny though, as the “old” templates are still mentioned, of course in their ASP.NET 3.5 web service documentation, but also in their Visual Studio 2010 ASP.NET Web services documentation :-)

A client recently asked me what space should reserve to store URLs in their DBMS.
The plurality in the topic title is a hint: different systems have different limits on URL lengths.
But first:
If you use long URL’s (longer than say a coupe of 100 characters), then usually you have a problem.
First of all: short URL’s are easier to remember, index and search.
Second: long URL’s can pose problems.
It might be that your browser and server support them.
But a user might be behind an intercepting proxy (sometimes invisible to both you and your user) that imposes a URL limit.
In stead of long URLs with a HTTP GET, use shorter URLs with a HTTP POST. Read the rest of this entry »

Every major release of software will bring great new stuff, but the price of upgrading from a previous version is that some stuff will break.
.NET 4.0 brings a lot of nice stuff as well, but there are a few things that break.
There is a nice Breaking changes in .NET 4.0 – Stack Overflow article on this.
The article is now a community wiki, and refers to these pages:
Since the article is a community wiki, expect it to be updated over time.
I wonder what these changes will bring (and break) in the upcoming Delphi Prism release (the datasheet is out now, the product should be out before the end of may).

PS:
If you do not have an MSDN subscription, but still want to see if things break for you, try one of these:
Scott Guthrie has a nice post on the bells and whistles of VS2010.

Google published an interesting graph generated from their internal data based on their indexed web pages.
A quick summary of popular encodings based on the graph:
Conclusion: if you do something with the web, make sure you support Unicode.
When you are using Delphi, and need help with transitioning to Unicode: contact me.
–jeroen
* Western European encodings: Windows-1252, ISO-8859-1 and ISO-8859-15.
Reference: Official Google Blog: Unicode nearing 50% of the web.
Edit: 20100212T1500
Some people mentioned (either in the comments or otherwise) that a some sites pretend they emit Unicode, but in fact they don’t.
This doesn’t relieve you from making sure you support Unicode: Don’t pretend you support Unicode, but do it properly!
Examples of bad support for Unicode are not limited to the visible web, but also applications talking to the web, and to webservices (one of my own experiences is explained in StUF – receiving data from a provider where UTF-8 is in fact ISO-8859: it shows an example where a vendor does Unicode support really wrong).
So: when you support Unicode, support it properly.

Finally someone who explains this topic well: CodeProject: Multi-Threading in ASP.NET.
Most of it is based on Web 405 “Building Highly Scalable ASP.NET Web Sites by Exploiting Asynchronous Programming Models” by Jeff Prosise, which should be here on the Microsoft events site (which currently has connection problems) and is referenced here and here.
Recommended reading!

Getting different architectures to talk can be a pain, even when using standards like SOAP.
In this case, the .NET WSDL imports Delphi generated WSDL in a different manner than you’d expect at first sight: when having both an ‘out’ parameter and a function ‘result’, the ‘result’ is not imported well.
But alas: SOAP didn’t accommodate for this situation in the past, and now SOAP now has some additions to solve this.
Bruneau Babet explains this here: [WayBack] SOAP inconsistency? Delphi 2010 (Win32) Server and .NET Client swapping ‘out-parameter’ and ‘result’. – Stack Overflow.
There he explains how to use the parameterOrder attribute, which the Delphi WSDL importer and exporter still do not support.

Today, I bumped into something utterly strange: requests replayed through Fiddler 2 to a locally running ASP.NET Development Server on Vista using localhost URLs did not give a connection.
I use ASP.NET from both C# and Delphi Prism. Most of my development work is on Windows XP (see notes below) but I test on many platforms.
Moving one of the projects from XP to Vista, and testing with Fiddler, I found that when using Fiddler 2:
This form of URL fails on Vista, but works on XP: http://localhost:49703
This form of URL works both on Vista, and XP: http://127.0.0.1:49703
So on Vista – contrary to XP – localhost requests from Fiddler were in fact being sent to the external network adapter on Vista, and the 127.0.0.1 requests to the internal network adapter.
Since the ASP.NET Development Server is bound only to the internal network adapter, external requests don’t work (boy, I wish they did, it would make some of my debugging so much easier!).
