Error accessing mscorlib.dll (2)

[Alonso]

Hi all,

I've created a Library class and inside the class (Class1) that inherits
from System.EnterpriseServices.ServicedComponent. In this class I wrote a
function with type: System.Guid and in the return sentence of this function I
wrote: return ContextUtil.ContexId.

In the same Solution I created a new project (Windows Application) and in
the event Load (Form1_Load) the code is:
Try
Dim obj As New Class1
Me.Label1.Text = obj.GetContextID.ToString
Catch ex As System.UnauthorizedAccessException
Me.Label1.Text = "El mensaje de error es: " & ex.Message
End Try

When line: Dim obj As New Class1 is executed I received an error:

Deny access. (The access refers to mscorlib.dll).

Any idea how to solve this error?

Thanks a lot.

Alonso.
