Assembly installed into the GAC not showing up in Visual Studio

Question

This sounds related to this question, but they aren't the same thing. That question had no assemblies showing up. Mine has everything except the specific one I installed.

I'm hoping someone has a solution to this... am I doing something wrong? Or did I find some bug in VS?

I am using Visual Studio 2010 Professional Beta 2 on Windows 7 Ultimate. I just downloaded Rhino Mocks and decided to install it into the GAC using the command-line utility GACUTIL. I then rebooted.

Here you can see the assembly in my GAC (click to enlarge):

And here is the list of assemblies available to me in Visual Studio:

Here is the command prompt where I installed it, and then confirmed it:

C:\Users\jason\Downloads>gacutil -i Rhino.Mocks.dll
Microsoft (R) .NET Global Assembly Cache Utility.  Version 4.0.21006.1
Copyright (c) Microsoft Corporation.  All rights reserved.

Assembly successfully added to the cache

C:\Users\jason\Downloads>gacutil /l |grep -i rhino
Rhino.Mocks, Version=3.6.0.0, Culture=neutral, PublicKeyToken=0b3305902db7183f, processorArchitecture=MSIL

Answer 1

Visual Studio never lists all items in the GAC. It only lists items that are noted in a particular registry key.

Please see this knowledge base article for more info: How to display an assembly in the "Add Reference" dialog box

You can always add a reference to the assembly by browsing to it on disk.
