Generates error in IE8 (Object doesn't support this action)

[stretford-end]

Object.defineProperty apparently has some quirks in IE8 and this causes this code to fail.

That's correct and it's not really possible to shim it the EcmaScript 5 way (non-enumerable property).
However I have tried to add an work-around so that both namespace and Enum to properly work outside VS2012.

Please let me know if this is good enough and I'll publish it to nuget.
