According to this section, I should be able to store DateTime in the local app settings. However, when I try to run the following code, I get an exception.

Windows.Storage.ApplicationData.Current.LocalSettings.Values["test"] = DateTime.Now;

Am I doing something wrong? Is there an issue with the document? Or is there a bug in the platform?

Figured out what went wrong. I created this PR to help improve the docs #1971

@dpaulino, thanks for the PR. DateTime is tricky because it shows up differently depending on the language you're programming in, so I also added a note that DateTimeOffset is for C# and .NET languages.
