Custom Attribute, Type in non-GAC assembly and the Toolbox

[Andrew Venmore]

Hello,

I am having a problem adding an assembly to the toolbox where it appears
VS2003 is unable to make sense of a type I am trying to initialise an
attribute with. Below is the simplest example which demonstrates the
problem.

I have two class library projects in my solution: BaseLib and ControlLib.
BaseLib declares a custom attribute and an enum, and ControlLib references
BaseLib and has a toolbox class and uses the custom attribute.

// BaseLib
using System;
namespace BaseLib {
[AttributeUsage(AttributeTargets.Class, AllowMultiple=true)]
public class cmiSecurityItemAttribute : Attribute {
// Ctor
public cmiSecurityItemAttribute(Type securityType) {
}
}
[FlagsAttribute]
public enum cmiSecurityAddEditDelete {Add=1, Edit=2, Delete=4}
}

// ControlLib
using System;
namespace ControlLib {
[BaseLib.cmiSecurityItemAttribute(typeof(BaseLib.cm iSecurityAddEditDelete))]
public class MyTextBox : System.Windows.Forms.TextBox {
}
}

If I try to add ControlLib to the toolbox, I receive the message "File or
assembly name BaseLib, or one of its dependencies, was not found.". If I
change the attibute use line to:
[BaseLib.cmiSecurityItemAttribute(typeof(bool))]
there is no problem adding ControlLib to the toolbox. So obviously VS can't
resolve the type BaseLib.cmiSecurityAddEditDelete when trying to add it to
the toolbox.

Does anyone have an idea what is going wrong here and a possible solution?
Is VS happy with "typeof(bool)" because it can find it in the GAC? I don't
want to add my BaseLib to the GAC. Any information would be much
appreciated.

TIA
