I fix this problem with doing debug :D

[isakatirci]

The Turkish alphabet character 'I' is pain in the neck. please take precautions for this

[tonysneed]

@isakatirci Would you be able to open a pull request with your fix?

Beware! I think ApplyChanges crushes with Dates in Cultures different from English.

It would be great to solve this matter.

Commented in #225. Would like to merge the PR but it needs to be re-done.

A release would be very appreciated. I am using URF.NET and this bug forces me to keep it in old version 4.2 . I tried to get development version of TrackableEntities, but it is labeled something below 2.5.7 - and URF.NET requires 2.5.7 at least. So I am stuck with 4.2, and old CommonLocator in turn as well.
