.net 4.0 compatibility -

-

i write winforms application, using .net 4.0, linq, etc. work on machines .net 2.0?

if use .net 4 features no, won't work on .net 2.

if just want use linq objects , no other newer features, should linqbridge, port of linq objects .net 2. can make visual studio target .net 2 in project properties, use linqbridge libraries, , app should work on .net 2 machine.

note still able use lot of features c# 3 , 4, such lambda expressions (but not expression trees), automatically implemented properties, anonymous types, optional parameters , named arguments etc. not available though - dynamic won't work on .net 2 example.
