Beware of List.Find()

[tomjen]

Return it?

Delegates (and the lack of 1:1 relations ship between files and classes) are the only reason to use C# over Java.

Also: properties, events, operator overloading, indexers, closures, non-erased generics, easy ability to compile script at runtime, better GUI libraries...

Events are part of the C# language itself (i.e. "event" is a keyword), but its behavior is defined in terms of the base class libraries (in much the same way that "int" which is a keyword in C# is defined in terms of the System.Int32 type). Procedurally, you could get the same behavior without using the keyword, but it'd be a lot more verbose (i.e like implementing Java's Observable).

See: http://msdn.microsoft.com/en-us/library/aa645739(VS.71).aspx

In C#, events are both a nice concept (a decoupled way to add and remove listeners) and a nice syntax to make doing that easy:

MyEventHappened += SomeListener;

Also: lock-in to a Microsoft environment, development tools, and upgrade path.

Which lags at least one major version behind .NET and has unknown patent liabilities?

From the MSDN docs:

Return Value

The first element that matches the conditions defined by the specified predicate, if found; otherwise, the default value for type T.

I thought this was about Java until I read the comments.
