c# - Could not load file or assembly 'System.Dynamic' or one of its dependencies -

-

i working on .net project 3.5 framework. getting error while run time.

i think system.dynamic resides in system.core dll, cannot find system.dynamic under system.core?

how can add in project?

system.dynamics not available in .net 3.5 - dlr (= dynamic language runtime) introduced .net 4.0 , not availalbe backport afaik.

the dlr , system.dynamics required use dynamic type. if want use that, need upgrade @ least .net 4.0.
