• C# PDA builds

  These are the buggiest builds I've ever seen from the C# team - that must be due to how early in the development cycle they are. For example, the following anonymous type produces some very strange error messages: class X { static void Main() { var x Read More...

• Buggy extension methods in C# v3

  Question: How do you call an instance method on null? What I mean is - how can I do something like null.ToString() ? Forgetting about why we would want to, here's how you do it (and exposing a bug in C# v3 in the meantime!) Answer: Define an extension Read More...

• Lambdas

  Maybe I should step back and explore lambdas in C# v3 a bit more. Ward Cunningham's c2 wiki has this to say: When such an expression is evaluated, it produces a function-object which can be called with the arguments implied by the LambdaList, and whose Read More...

• JIT performance affected by C# v3

• Query Expression shortcut operators

  I decided I didn't need the IDE after watching some of the LINQ videos - Notepad is my friend. So, after little ado, let's jump into LINQ.

• How to destroy enthusiasm. A course by Microsoft

  So LINQ looks cool. The support in C# and VB.Net looks cool. And Paul Vick says all this stuff runs on the Whidbey CLR - all I need is VS.Net 2005 Beta2 and the LINQ preview. So I go to download VS.Net 2005 beta 2 and find that I can only download it Read More... Posted Wednesday, September 14, 2005 1:35 PM by rbirkby | 5 Comments Filed under: C#

• Katrina prophecy

  In 2003, the New Orleans Times-Picayune wrote a 5-part series considering what would happen with a large cat-5 hurricane. Their analysis is eerily prophetic. But just getting into the city will be a problem for rescuers. Approaches by road may be washed Read More... Posted Friday, September 02, 2005 4:23 PM by rbirkby | 0 Comments
