Charlie, can't wait to read about the LINQ performance enhancements. Any chance there's information on the web on the subject already?

Thanks in advance!

Microsoft has recently released an updated training kit with presentations, hands-on labs, demos and

Where is a detailed list of changes such as listing new/changed .NET framework methods?

Just wondering where System.Windows.Controls.WegbBrowser is? A previous blog entry stated that it was going to be included with SP1, but, it appears to not be there.

Does anyone know when/if this will hit WSUS?  The .NET Framework 3.5 itself still is not on WSUS.

The following program will run under 3.5, but fails with an exception on the second line after SP1 is installed:

class Program

{

   static void Main(string[] args)

   {

       int[] ints = { 1, 2, 3, 4 };

       string[] strings = ints.Cast<string>().ToArray();

   }

}

An InvalidCastException gets thrown from the generic Cast call.

Do we have an alternative method of casting the elements of an array?

The Cast operator was always intended to cast an untyped collection (i.e. IEnumerable) to a typed collection (i.e. IEnumerable<T>). The fact that it was also capable of executing type casts on elements was a mistake in the implementation. The correct way to perform a type cast on each element is to use the Select statement:

ints.Select(i => i.ToString())

Can anybody explain this:
