Compiling to EXE succeeds but not to DLL

[Terentius Neo]

I have two classes, A and B, both in the same namespace. If I compile
files to a DLL, the A class does not compile. The error message is

"[C# Error] BaseObject.cs(69): The type or namespace name 'Logger' could
not be found (are you missing a using directive or an assembly reference?)"

Note: there *is* using clause.

If I compile both as part of the same EXE there is no problem. The code
is the same!
Class A:
==========
using COM.ISADGBase.Objects;

namespace COM.ISADGBase.Objects
{
public abstract class BaseObject : IDescLevel {
//THE NEXT LINE DOES NOT COMPILE:
protected internal Logger log;
}
}

Class B;
==========
using COM.ISADGBase.Objects;

namespace COM.ISADGBase.Objects
{
public class Logger
{
}
}

With best regards
Terentius

Terentius,

A using clause is not the same as an assembly reference. If you are
compiling from the command line, you need to add an assembly
reference for the assembly that contains the Logger class:

csc /t:library /r:Logger.dll BaseObject.cs

If you are using Visual Studio, expand the References node for the
project in the Solution Explorer and add a reference to Logger's
assembly.
