I am writing a class library where i need to extend System.DateTime to have a property called VendorSpecificDay such that

```
DateTime txnDate = DateTime.Today;

VendorSpecificDayEnum vendorDay = txnDate.VendorSpecificDay;

```

---

```
public enum VendorSpecificDayEnum
{
    Monday, Tuesday, ShoppingDay, HolidayDay
}

```

I realize that this is a perfect candidate for a System.Core Extension method, but the class library is in .net 2.0 ( i know i am living in dark ages )

Given that Extension methods are syntactical sugar, is there anyway i can achieve this without them ?

Many Thanks
