Calling a method every x minutes

I based this on @asawyer's answer. He doesn't seem to get a compile error, but some of us do. Here is a version which the C# compiler in Visual Studio 2010 will accept.

var timer = new System.Threading.Timer(
    e => MyMethod(),  
    null, 
    TimeSpan.Zero, 
    TimeSpan.FromMinutes(5));

var startTimeSpan = TimeSpan.Zero;
var periodTimeSpan = TimeSpan.FromMinutes(5);

var timer = new System.Threading.Timer((e) =>
{
    MyMethod();   
}, null, startTimeSpan, periodTimeSpan);
