I have been using a modified version of the BlogEngine.NET Twitter widget that I got from Al Bsharah, but noticed that it doesn't correctly create the link for Twitter user names that contain an underscore.

An easy fix for this is to modify line 354 of his widget.ascx.cs file to include an underscore in the regular expression:

private static readonly Regex regex2 = new Regex("@[a-zA-Z0-9_]*", 
                                        RegexOptions.Compiled | RegexOptions.IgnoreCase);

UPDATE May 1, 2010: The original has now been updated.

So you've switched to Enterprise Library 5.0 and you're now finding compiler errors relating to generic implementations of .Resolve, .RegisterType, etc. in your UnityContainer? These are now extension methods, so just add the following to your class and your problem will be solved:

using Microsoft.Practices.Unity;

I recently updated my component for calculating public holidays and have decided to share the C# source.  This is currently configured for South Africa, but can easily be updated to support any other country you choose (see the config file in the unit test project).

The standard holidays are stored in a custom configuration section as month and day, while easter is calculated for the specific year in question.  The provider determines if a public holiday falls on a Sunday and rolls it over to the Monday, as per South African standard (this behavior can be disabled in the configuration).

Enjoy. Any feedback would be appreciated.
