Indexed Properties in C# 4.0

In C# 4.0 you can call parameterized properties that are declared in other languages (VB, COM, C++, etc) using the indexer syntax, for instance instead of excel.get_Range("a") you can now write excel.Range["a"]. You still can’t declare your own indexed properties from C#. The feature is immediately available in Visual Studio 2010 Beta 2 for your indexing pleasure.
