With "D:\Applications\Mono-3.0.9\bin" and
"C:\Windows\Microsoft.NET\Framework\v4.0.30319" in the path on my Windows 7
machine:

===== Test.cs =====
using EnvDTE;

class TestClass
{
    void TestMethod(DTE dte)
	{
	    var cancelBuildCmd = dte.Commands.Item("Build.Cancel");
		var cancelBuildEvents = dte.Events.CommandEvents[cancelBuildCmd.Guid, cancelBuildCmd.ID];
	}
    public static void Main() {}
}
===== end =====

Quite weird COM case where we need to support CommandEvents both as a property and as method like indexer (not implemented)
