c# - Why can't I reference a class in another namespace in another project within the same solution? -

-

i have created namespace in project within same solution. when type using other namespace shows up. cannot see public class within namespace. what's wrong ?

since type public, sounds simple missing project reference between two. right click references , add new reference, watch references shouldn't become circular (i.e. <===> b, or ===> b ===> c ===> a). actually, vs ide doesn't let this, can done (accidentally or purposefully) via command-line tools.
