I assume this must have been noted before but either I don't know how to search this discussion forum or I am doing something stupid in my project. I get a compile error in line 65 of SimpleWebToken.cs:
ulong.Parse(values).ToDateTimeFromEpoch();
since ToDateTimeEpoch is defined as an extension method on long, not ulong. I modified this line from ulong to long and now it compiles and runs fine. Why am I not seeing many other people reporting the same issue?
