can't reference class from another project of the same solution

Question

My solution contains several projects including Commons and TerminatorConsole2. Now I want to refer Commons.Constants class from Ter

Answer 1

By default the scope of class is internal which mean could be accessed within that assembly Make the class public in order to make it accessible to other assemblies. More about access modifiers Also make sure you added the reference of assembly you are reffering.

Change

class Constants
    {
        public const string MANAGEMENT_CONSOLE_ADDRESS =
            Commons.Constants.USE_EXTRA_WCF_INSTANCE ?
                "net.pipe://localhost/xxx" :
                "net.pipe://localhost";

To

public class Constants
    {
        public const string MANAGEMENT_CONSOLE_ADDRESS =
            Commons.Constants.USE_EXTRA_WCF_INSTANCE ?
                "net.pipe://localhost/xxx" :
                "net.pipe://localhost";
