C# 3.0? You haven't even shipped 2.0 yet?

One of my readers commented (and I'm paraphrasing here): Why are you asking me about features for the next version of C#, when the 2.0 version hasn't even shipped yet? A fair question. One of the problems that we have in the tools division is the long

Memories of Youth

I remember the hot summer days of my youth. Our backyard patio had ants. I had a 5” magnifying glass. You can guess the rest. I've always had a soft spot for the power of focused sunlight, though I never took it as far as the creators of Melt Man

using - It's not just for memory management

When we designed the using statement waaaay back in the first version of C#, we decided to call it using because we thought it had other purposes outside of the usual use: using (StreamWriter writer = File.CreateText(”blah.txt”)) { ... } Today

Stevens Pass Summit Lakes (Grace Lake)

Last Sunday, we went on a short hike to the summit lakes at Stevens Pass Ski Area. It was the first hike for us this season, and the first one with canine company. The real trail starts at the top of the Brooks lift (roughly centered in the photo). But

Not sure what to make of this...

Go http://www.ilovebees.com/ . Wait for it. then, perhaps go here and here . I really don't know what - if anything - this is. But whatever it is, it's interesting...

Answer: What is the lifetime of local instances?

Answer to this poser I wasn't sure the answer to this question was observable, so I wrote a short program: using System; class Early { ~Early() { Console.WriteLine("Early Cleaned Up"); } } class Test { public static void Main() { Early e = new Early();

Poser: What is the lifetime of local instances?

A reader wote me to ask a question about variable lifetimes. Consider the following code: class Mutex { public Mutex(string name) { hMutex = Kernel32.CreateMutex(null,false,name); Kernel32.WaitForSingleObject(hMutex,0); } ~Mutex() { Kernel32.ReleaseMutex(hMutex);

Why language features die, and language extensibility

Rick Byers wrote (some time ago): Thanks for the awesome post Eric. I'd be interested in hearing more detail about the sorts of things that cause features to be rejected. Is it common to reject a feature that you think would be valuable only because of

Future language features & scenarios

We're starting to think about the release after Whidbey in the C# compiler team. I know that it seems strange that we have just shipped the Whidbey beta, and we're already talking about what comes next, but we're fairly close to being “shut down”

Why a manned space program?

One of the questions about in the comments to my post on Apollo question asked “Why do we have a manned space program? That's a fair question, but before I answer it, there are two things I want to talk about. The first is to give credit where credit

35 years ago today...

35 years ago, two men came within 20 seconds of dying 250,000 miles away. Hours after averting tragedy, a very young Eric Gunnerson got to stay up late to watch Neil Armstrong walk on the moon. I was 5. I've always been a bit of a space nut, and my memory

Naming generic type parameters...

There's been quite a discussion going on on the MSDN feedback site over the naming of generic type parameters. If you look at the definition of the generic collections classes, you'll see things like: List<T> Dictionary<K, V> What's up with

Alfred is worried...

Those of you who read my holiday letter post from last year may remember that Alfred is my Roomba. That is, if you haven't blotted the experience of reading the post out of your mind. See, I warned you, and what did you do - you went back and looked at

Google is my personal search engine

Google gives high weight to blogs. In fact, google gives too much weight to blogs. Too often I've gone to research something that I only know a little about (say, training for a century ) and found that my post is on the first page of results. Want to

Fixed statement and null input...

I'd like some input on a change we're considering for Whidbey. Consider the following wrapper class: unsafe class Wrapper { public void ManagedFunc(byte[] data) { fixed (byte* pData = data) { UnmanagedFunc(pData); } } void UnmanagedFunc(byte* pData) }

Decreased performance when compiling with no options...

One of the things that we've done in Whidbey is add some extra IL instructions to improve the debugging experience. This allows you to (for example) set a break on a closing brace. Because /o- is the default setting, this means that performance if you

Le Tour

This week starts part of my favorite part of the summer, “Le Tour de France”. The tour is likely the hardest athletic challenge in the world. Last year, Armstrong covered 2100 miles at an average speed of just under 26 MPH, including 7 days

Extending existing classes

One other point that came up in the static import thread was extending existing classes. It's not uncommon to want to add specific methods to existing classes - or at least have the appearance of doing this. For example, I might want to add a new method
