We created Activation Context in C# and managed to reproduce the issue
without setting the Isolation flag set. The test method below FAILS if
called as a test from NUnit version 2.5.10.11092 when COM dll is
unregistered (but in same folder) but WORKS when called from another
exe:

Test Error : ClassLibrary1.Class1.test()
   System.IO.FileNotFoundException : Retrieving the COM class factory for component with CLSID {XXXXXXXXXXXX} failed due to the following error: 8007007e.

  You need to provide your native COM .dll with "OurLib.OurClass"
component and a file OurLib.X.manifest.  The COM.dll has to be
registered when building the C# ClassLibrary1.dll and unregistered to
run the test

        public void test()
        {
           string fullPath = (new System.Uri(Assembly.GetExecutingAssembly().Location)).AbsolutePath.Replace("ClassLibrary1.DLL","");             
            string manifest = @"OurLib.X.manifest";

            NativeMethods.ACTCTX info = new NativeMethods.ACTCTX();
            info.cbSize = Marshal.SizeOf(typeof(NativeMethods.ACTCTX));

            info.lpAssemblyDirectory = fullPath;
            info.lpSource = fullPath + manifest;
            IntPtr hActCtx = NativeMethods.CreateActCtx(ref info);

            IntPtr cookie = IntPtr.Zero;
            bool bOK = NativeMethods.ActivateActCtx(hActCtx, out cookie);

            OurLib.OurClass c = new OurLib.OurClass();

Title:
  Isolated COM class referenced in the test DLL not found

Status in NUnit V2 Test Framework:
  New

Bug description:
  Create .Net ClassLibrary1 that references a registered COM component
  and contains a class with a [TestCase] method which uses the COM
  object. Set Isolated in the References to true [that will add
  ClassLibrary1.manifest with <file> section]. Unregister the COM
  component. The nunit test will fail with:

   Test Error : ClassLibrary1.Class1.test()
     System.Runtime.InteropServices.COMException : Retrieving the COM class factory for component with CLSID {###} failed due to the following error: 80040154.
     at ClassLibrary1.Class1.test() in C:\temp\Projects\ConsoleApplication1\ClassLibrary1\Class1.cs:line 13

  An C# console application that references the ClassLibrary1 wil work
  fine.
