phantom namespace across assemblies

[Dan Holmes]

I can't find where i have declared ICategoryService as being in the
IVS.WMS.Product namespace. I have recompiled. Deleted the obj and bin
dirs. Removed the reference. I can't figure out how the Server dll
thinks the ICategoryService interface is in the IVS.WMS.Product
namespace instead of the one that is defined in Common (just IVS.WMS).


The error that is given

..\IVS.WMS.Category.Server.dll => Could not load type
'IVS.WMS.Product.ICategoryService' from assembly 'IVS.WMS.Category.
Common, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

I have narrowed down to this: The GetTypes() method causes the
exception. I have used Reflector on this assembly and it doesn't have
any problem. The interface it says it can't find doesn't exists and i
can't find a usage of that interface in the code for this assembly.

private void button1_Click(object sender, EventArgs e)
{
try
{
System.Reflection.Assembly a =
System.Reflection.Assembly.LoadFrom(@"c:\sandbox\iaf.net\serverinstall\IVS.WMS.Category.Server.dll");
Type[] t = a.GetTypes();

}
catch (System.Reflection.ReflectionTypeLoadException ex)
{
foreach (Exception e1 in ex.LoaderExceptions)
MessageBox.Show(e1.ToString());
}
catch (Exception ex)
{

MessageBox.Show(ex.ToString());
}
}
