Hello Andrew Jameson ,

The problem occurred because in the GroupShareKit(2015 branch) the "DueDate" was not nullable, you should update to the latest version of GroupShareKit via Nuget, which will fix this issue.
Hope this helps.

Regards,
Alexandru-Constantin Pascariu

The latest version of GroupShareKit is for GS 2017 - won't this use v2 of the REST API? I.e., won't it contain "v2" in the URI for each API call, whereas the 2015 branch contained "1.0" in the URIs?

My concern is that if I were to upgrade to the latest GroupShareKit then there will be even more breaking changes.

Edit: I've updated my NuGet reference to the latest version but this introduces many more errors - some methods require different parameters, other methods no longer exist. This is why I wanted to remain with "v1" of the API until we have time for a larger rewrite/refactoring.

Why bother versioning the API if SDL are going to make breaking changes to that version when modifying the API for a newer version? Didn't SDL consider that people were using v1 of the API?

Hi Alexandru-Constantin Pascariu

is it possible also to include a fix for following issue: https://github.com/sdl/groupsharekit.net/issues/14 into the new version for 2015?

Thanks for your help!
