c# - System.Threading.Tasks conflicts in MathNet.Numerics and Parse -

i developing unity project need use both mathnet.numerics , parse. problem both need access system.threading, since unity allows 3.5, both ship own. parse have, however, embedded part need parse-dll, missing parts (system.collections.concurrent) mathnet.numerics needs. means cannot used mathnet. can not add both unity project since system.threading needed mathnet.numerics conflicts namespace embedded parse.unity.dll.

i have no idea how solve this. tried similair?

mathnet requires .net 4.0 or newer , parse supports .net 4.5 or newer, unity supports .net 3.5.

for math portion need find library targets 3.5 if want use in unity project, way make mathnet work 3.5 if re-wrote source code not use 4.0 or newer features (not easy task).

for parse, need find different library provides same features. there source parse not available not able re-write it.
