Trying out Sharp Tests Ex with NUnit 2.5
/*before*/ Assert.That(logHandlersCount, Is.EqualTo(1));
/*after*/ logHandlersCount.Should().Be.EqualTo(1);
Even better readability :-)

A NUnit Custom Constraint together with a String Extension Method
[Test]
public void WhenMyStringPropertyIsEmptyThenMyEntityMustBeInvalid()
{
var myEntity = new Entity { MyStringProperty = string.Empty };
Assert.That(myEntity, "MyStringProperty".IsIncludedInBrokenRules());
}
IsIncludedInBrokenRules() is an extension method that returns an instance of a class that inherits Constraint.

SQLite - works on my machine ;-)
I have this new and shiny HP Z600 (x64) at work.
Recently I started using SQLite in-memory for unit testing NHibernate persistence logic.
When committing, my dear colleague with an older x86 machine got problems...
I reproduced the problem on my machine by setting the build target to x86 in VS08.
Just change to the 32-bit version of SQLite did the trick.
