[MSDNWiki] MSDNWiki RSS# (New RSS feed for MSDNWiki)
For those of you living in a cave I present - MSDNWiki.
Looks nice and very useful. However, Look closer. Look at the MSDNWiki Rss feeds. MSDNWiki has two Rss Feeds: New blocks and New edits. I've got no idea what's the difference between those two feeds. I can guess, but I'm not sure. Also, These RSS feeds are extremely non-informative. All you know is that some guy (who's name you know) made an edit somewhere and you get a link to the relevant MSDNWiki page. That's great in case you have TIME to open 300 MSDN pages each week (and rising), I don't.
I need a MSDNWiki RSS feed that actually tells me all I need to know.
So I built MSDNWiki RSS#.
Check it out at http://www.justinangel.net/msdnwiki/MSDNWiki.aspx.
What's cool about it:
1. The title of each RSS post in MSDNWiki RSS# is the Title of the edit/block AND the MSDN page the edit was done at. This is extremely important! the old feeds didn't even say where the edit/block was. You simply had to guess.
in stand of "this doesn't do what you expect" you get "This doesn't do what you expect. (NetworkStream.CanWrite Property (System.Net.Sockets))".
2. There's only ONE feed - not two feeds.
3. Full Community edit content. Not just the half of the first sentence. You get all the community content, right in your RSS reader.
4. Full MSDN content. If you don't understand some comment made about the MSDN value - you have it in front of you. no more opening MSDN pages & waiting for them to load just so you can understand what the heck this guy is talking about.
5. Filter by phrase. You don't have to suscribe to the full feed, you just need say what interests you. just type your search value in the "filter" querystring variable. For example:
- "System.web.ui" - http://www.justinangel.net/msdnwiki/MSDNWiki.aspx?filter=System.Web.UI
- "yield" - http://www.justinangel.net/msdnwiki/MSDNWiki.aspx?filter=yield
- "Visual basic" - http://www.justinangel.net/msdnwiki/MSDNWiki.aspx?filter=Visual%20Basic
Just subscribe to http://www.justinangel.net/msdnwiki/MSDNWiki.aspx?filter=Your phrase here.
6. Doesn't show duplicate edits/blocks. MSDNWiki RSS# checks you only get the latest changes and not twenty links to the same page.

If you need more features, want to report a bug or anything else - Just ask. Thanks to Miki Watts for beta testing.
Here's an example of MSDNWiki original RSS feeds VS. MSDNWiki RSS# feed on the "yield" update. After you see this - you choose which feed you rather subscribe to.

ADDITIONAL NOTES:
You also use System.Collections.Generic.IEnumerable<T> as return type of iterator block.
A yield statement can not be used in body of finally block.
Using try/finally blocks with yield return statement inside them is unsafe if iteration performed using MoveNext/Current methods. Execution of statements inside finally block is not guaranteed. They will be executed only after all values before block will be iterated and next one requested OR IDisposable.Dispose method called on IEnumerator. Finally statements will not be executed during garbage collection as compiler generated iterator class have no finalizer. Using with foreach is safe as compiler will generate call to Dispose.
MSDN original Content
yield (C# Reference)
Used in an iterator block to provide a value to the enumerator object or to signal the end of iteration. It takes one of the following forms:
yield return <expression>;
yield break;
expression is evaluated and returned as a value to the enumerator object; expression has to be implicitly convertible to the yield type of the iterator.
The yield statement can only appear inside an iterator block, which might be used as a body of a method, operator, or accessor. The body of such methods, operators, or accessors is controlled by the following restrictions:
-
Unsafe blocks are not allowed.
-
Parameters to the method, operator, or accessor cannot be ref or out.
A yield statement cannot appear in an anonymous method. For more information, see Anonymous Methods (C# Programming Guide).
When used with expression, a yield return statement cannot appear in a catch block or in a try block that has one or more catch clauses. For more information, see Exception Handling Statements (C# Reference).
In the following example, the yield statement is used inside an iterator block, which is the method Power(int number, int power). When the Power method is invoked, it returns an enumerable object that contains the powers of a number. Notice that the return type of the Power method is IEnumerable, an iterator interface type.
// yield-example.cs
using System;
using System.Collections;
public class List
{
public static IEnumerable Power(int number, int exponent)
{
int counter = 0;
int result = 1;
while (counter++ < exponent)
{
result = result * number;
yield return result;
}
}
static void Main()
{
// Display powers of 2 up to the exponent 8:
foreach (int i in Power(2, 8))
{
Console.Write("{0} ", i);
}
}
}
