Is it possible to see what version of .NET an assembly was built in?

Question

I don't need to do it from code or anything. Just need to find out from windows.

Answer 1

You can use Reflector

For example if you open log4net in reflector, you can see it's Target Runtime.

PS: BTW this new upload image feature is really cool

Answer 2

You can't easily find out without checking dependencies.

You can use .NET reflector or Dependency Walker to do that.
