I created a new file-system based web site in Visual Studio 2010. On property pages I've set to use .NET 4.0, but I cannot find System.Windows in the Add Reference dialog. The only copy on my PC seems to be in this directory, but this is not a Silverlight project
C:\Program Files\Reference Assemblies\Microsoft\Framework\Silverlight\v4.0
I thought it might have something to do with the client profile vs full version, but I can't see where to specify that in a web site project.
What am I doing wrong?
Not all namespaces have corresponding DLL file names used in the Add Reference dialog. System.Windows is one of these.
For example, System.Windows.Clipboard is resident in the PresentationCore.dll, but System.Windows.SizeConverter is in WindowsBase.dll. It all depends on the actual types you need to access.
System.Windows is the WPF base classes - you cant add that assembly to an ASP.NET site. You will need to change your application type to use it.

So I've looked around to try to find some posts on this and there are many but none that address my specific question (that I could find).
I am trying to add some DLL's in my project but few of them are coming from :
C:\Windows\Microsoft.NET\Framework\v3.5\XXX.YYY.dll
and what I expecting this should be coming from GAC.
Please suggest me the best practice to reference the Dll's in Visual Studio.
That's not the way it works. When you use Project + Add Reference then you always add a reference assembly. This is never an assembly from the GAC. The GAC is a runtime implementation detail, it is only ever used to supply assemblies when your program executes, never when it is built.
It is very important that it works that way, the content of the GAC on your machine will not match the content of the GAC on your user's machine. Lots of DLL Hell countermeasures are in place to ensure the mapping of your reference assembly to the user's GAC content is taken care of with good diagnostics when the user's machine isn't configured correctly to execute your program.
This is also the reason that you cannot directly look at the GAC folders when you navigate to c:\windows\assembly with Explorer. A shell extension handler hides the details to stop you from making a mistake like adding a GAC-ed assembly as a reference assembly. This same extension handler is not installed for the .NET 4 assemblies, you can look at c:\windows\microsoft.net\assembly and see the structure of the GAC. Do not assume that it is now okay to add references from there, reference assemblies are even more important in .NET 4, they are completely different from the runtime assemblies.
So seeing the reference assembly stored in C:\Windows\Microsoft.NET\Framework\v3.5 is completely normal, that's the home directory for .NET 3.5 specific reference assemblies, like System.Core.dll. For .NET 4 projects the reference assemblies are stored in c:\program files\reference assemblies, they should not reference C:\Windows\Microsoft.NET\Framework\v4.0.30319. Check this answer to see what kind of undiagnosable misery can be caused by not using the correct reference assemblies.
Those assemblies are assemblies of the .NET Framework 3.5. The assembly cache is located at
%SystemRoot%\assembly
You may distribute the .NET Framework 3.5 (scroll the the end of the page) together with your project. Aso if you are using VS Setup projects you can simply use the properties page to reference it.
To reference those assemblies you can easily right-click "References" > "Add Reference" and choose the assembly from the .NET tab. For referencing GAC assemblies refer to this question.
We are the providing custom controls for all platforms in Visual Studio .Net. We are adding assemblies into ToolboxControlsInstaller and Register the assemblies in AssemblyFoldersEx under the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft.NETFramework. When use the Add reference (to add assemblies C# projects) for Windows Phone Projects, it shows all platform assemblies from GAC like MVC, Windows and WPF. Is there any possible to filter assemblies and show only phone assemblies for Windows Phone Projects. Please help me to resolve the issue. Thanks in advance.
Try using the Productivity Power Tools for Visual Studio!
It replaces the default "Add Reference" dialog with a better one, and on top, shows that it is filtering the references by platform!
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SDKs\Silverlight for WindowsPhone\v4.0\AssemblyFoldersEx
If we create a new Key under the above registry location then set the Assemblies location as default value. Then put what are the assemblies we want to add in Add Reference tab in that location. It will resolve this issue.
I've generated pseudo-localized versions of an app's resource files (for example Order Summary and Payment is localized as [[[[[Òŕd̂ër̊ S̀úm̂m̈år̀ý ân̈d̊ P̀áŷm̈e̊ǹt́]]]]]) so that we can test for localizability bugs ahead of getting actual translations.
I have named them using the qps-ploc resource identifier to match the existing pseudo-locale identifier, e.g. my pseudo-localized version of Details.resx is named Details.qps-ploc.resx.
However when I add these resx files to the project, Visual Studio ignores them. If I rename them using a "real" language code (such as Details.fr-FR.resx) then Visual Studio does create a subfolder named with this language code and builds the satellite assembly.
So it looks to me like Visual Studio rejects qps-ploc (without even a build warning). Am I missing something or can anyone suggest a way to get these qps-ploc resources built as part of my Visual Studio project?
The qps- locales work fine in my ASP.NET web application with .resx files (not compiled resource dll), however, I did find this MS article on enabling pseudo locales in the registry. Perhaps it will help.
Using Pseudo-Locales for Localization Testing
Additionally, you may wish to create custom locales, as given in this MS article:

Best regards.
I have installed the strong named assembly TestReflection into the GAC (I am using .NET 4.0 and VS 2010).
Different versions of the TestReflection DLL are in GAC of .NET 4.0 (C:\WINDOWS\Microsoft.NET\assembly\GAC_32\TestReflection\), however, the assembly does not appear in the "Project" -> "Add reference" box of VS 2010.
How can I refer to my assembly deployed in GAC at design time from another project?
This page says that:
You cannot add references from the Global Assembly Cache (GAC), as it is strictly part of the run-time environment.
Referring to this statement, I would like to know how to make your project's DLL shared assembly for other consumers if it's the requirement?
The dll's shown in the .Net tab of the "Add references" dialog are not actually the ones registered in the GAC. They are found by searching a few paths on your filesystem.
The paths being searched are located by Visual Studio by looking up the following registry entries:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NetFramework\{Version}\AssemblyFoldersEx\
There should be some keys added there already, so if you want your own dll to show up on the .Net tab, you can add it to one of the folders defined there. You could also add a new registry key pointing to a custom folder, which would only contain your own dll's.
The GAC is only meant for loading assemblies at runtime after your application has been deployed, so I don't think you should use it while developing. When you deploy your app, make sure to set "Copy local" to false on your reference so the dll won't be copied to the bin folder, and then install it into the GAC and it will be loaded from there instead.
Another simple option would be to manually edit the project file as XML in visual studio (You will have to unload the project first), and simply add node <Reference Include="<name of dll>" /> in MSBuild project file. After reloading the project, VS will pick up the reference without problem.
If you want to add Global Assembly Cache references to your VS2010 project, there is an extension you can use: Muse.VSExtensions.
It has some quirks but does a decent job. Check it out...
The answer is the Reference Paths in the property windows, you have to set it with the GAC path
Please see my post here:
This assembly is in the GAC: Microsoft.SqlServer.Management.RegisteredServers.dll
How can I add a reference to this assembly in Visual Studio?
I can view the file in c:\windows\assembly\
As the others said, most of the time you won't want to do that because it doesn't copy the assembly to your project and it won't deploy with your project. However, if you're like me, and trying to add a reference that all target machines have in their GAC but it's not a .NET Framework assembly:
Open the windows Run dialog (Windows Key + r)
Type C:\Windows\assembly\gac_msil. This is some sort of weird hack that lets you browse your GAC. You can only get to it through the run dialog. Hopefully my spreading this info doesn't eventually cause Microsoft to patch it and block it. (Too paranoid? :P)
Find your assembly and copy its path from the address bar.
Open the Add Reference dialog in Visual Studio and choose the Browse tab.
Paste in the path to your GAC assembly.
I don't know if there's an easier way, but I haven't found it. I also frequently use step 1-3 to place .pdb files with their GAC assemblies to make sure they're not lost when I later need to use Remote Debugger.
Registering assmblies into the GAC does not then place a reference to the assembly in the add references dialog. You still need to reference the assembly by path for your project, the main difference being you do not need to use the copy local option, your app will find it at runtime.
In this particular case, you just need to reference your assembly by path (browse) or if you really want to have it in the add reference dialog there is a registry setting where you can add additional paths.
Note, if you ship your app to someone who does not have this assembly installed you will need to ship it, and in this case you really need to use the SharedManagementObjects.msi redistributable.
I've created a tool which is completely free, that will help you to achieve your goal. Muse VSReferences will allow you to add a Global Assembly Cache reference to the project from Add GAC Reference menu item.
Hope this helps Muse VSExtensions
In VS2010, from the Add Rerences window you can click 'Browse' and navigate to C:\Windows\Assembly and add references to the assemblies that you want. Please note that the files may be grouped under different folders like GAC, GAC_32, GAC_64, GAC_MSIL etc.
In VS, right click your project, select "Add Reference...", and you will see all the namespaces that exist in your GAC. Choose Microsoft.SqlServer.Management.RegisteredServers and click OK, and you should be good to go
EDIT:
That is the way you want to do this most of the time. However, after a bit of poking around I found this issue on MS Connect. MS says it is a known deployment issue, and they don't have a work around. The guy says if he copies the dll from the GAC folder and drops it in his bin, it works.
The only way that worked for me, is by copying the dll into your desktop or something, add reference to it, then delete the dll from your desktop.
Visual Studio will refresh itself, and will finally reference the dll from the GAC on itself.
Assuming you alredy tried to "Add Reference..." as explained above and did not succeed, you can have a look here. They say you have to meet some prerequisites:
- .NET 3.5 SP1
- Windows Installer 4.5
EDIT: According to this post it is a known issue.
And this could be the solution you're looking for :)
May be it's too late to answer, but i found a very simple way to do this(without a hack).
Put your dll in GAC (for 3.5 Drag Drop inside "C:\Windows\assembly\")
GoTo Projects --> Properties
Click Reference Path (for 3.5 it's "C:\Windows\assembly\")
and Build
Hope it helps
