I have a c# project X that contains a folder COMMON, and I have several classes in the COMMON folder.
Now in project Y; I am referencing
using X.Common;
Everything is good till now, intellisense works great.
However, when I build project Y I get “The type or namespace name ‘common’ doesn’t exists in the namespace X(are you missing an assembly reference?”
In visual studio, in project Y. Right click references, add reference, projects, select Project X. Try again.
