I remember being able to do this but I must have changed something as I can no longer view an external projects source even though the pdb is with the reference. I can step into external functions when debugging but I can't go to them using "Go to implementation/declaration"
This will work if you have a separate class library Project as a part of your Solution, and you added a reference to the Project, not the compiled .dll.
You cannot step into a .dll when debugging.
It's all in how you add the reference.

I have a solution using to projects: a class library project, and a console application referencing this. Now when I try to debug the console application, it loads the class library from the GAC, not the version from the "sister project" of the solution. I just have changed one line of code in the class library project, and the debugger now just shows me the disassembly instead of the C# source code for methods in the class library.
How can I get VS2015 to load the assembly version from the sister project, not the version from the GAC?
If the same dll file was in the GAC, it would be loaded firstly, I think it is the reason why it ignored the reference project. So if you really want to use the project reference, you really need to remove the GAC.
Of course, other members also provided the suggestion like using the version numbers:

I have a C# project which contains references to assemblies in DLL format. I have the PDB information for these DLL files, contained in the same folder. When I press F12 on a referenced member, I want to go to the definition of the member. Instead, it gives me the metadata, which of course I don't want.
When VS is debugging, it does go to the source code if I single step into that method. But if I press F12 on that method, it still brings me to the metadata.
There is a similar question here, but it only applies to project references, and the accepted solution has nothing to do with my issue.
"Go To Definition" in Visual Studio only brings up the Metadata
To summarize:
Referenced project is a DLL
I have the PDB information
Single-stepping in debug-mode brings me to the source code
F12 brings me to metadata
I want F12 to bring me to the source code as debug does.
EDIT: Adding as a "Project" is not an option as it creates additional complexity as our solution file references about five other projects which are all under separate source control repositories.
In Visual Studio expand the References section, select the reference to your related project (the one that contains the source code you want to F12 into) right click on it and select "Remove".
Then add the reference back to the project by right clicking on References and selecting Add Reference, under the Projects tab (if your using VS 2012) select (or browse for) the project you want to add a reference to and then click the OK button.
This will rebuild the reference and you will be able to F12 into the referenced projects source code. You will need to do this with all the projects in your solutions that are having this issue.
I don't know why this happens but at least the solution to the problem is rather simple
If you have ReSharper installed, you should bring up ReSharper options, and look for External Sources. There you can specify the relevant options:
It appears that this issue has been solved in Visual Studio 2013. Having the PDB information in the same folder as the DLL is showing me the source code when I use Go To Definition. I do not have the Reflector extension installed.
Is the referenced DLL a project in your solution? I find that when I have the source code for the project, and it's in my solution, Visual Studio is able to link to this code much more easily. (without showing me meta data).
Also, be sure to add the reference by "Project" in the References popup.
This is generally what I do anyways when I have this problem
Hope this helps!
PS. PDB files are usually just for debugging (both locally and remote) and are not used for source code reading in the way you are attempting to use it. ("Go To Definition")
One solution to this issue is to use .NET Reflector, VS or VSPro edition. This program will modify Visual Studio to provide the required functionality.

Unfortunately, it costs $135 to $195, which isn't an option for everybody.
Add the reference as a project instead of ..\bin\Debug\referenceFile.dll
That solved my issue
I also used add reference as a project and my problem has been resolved and it's working great. Actually I was stuck at this point from very long time and finally i resolved this issue.
References -> Add References -> Solution -> Projects -> Select reference
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.
I am using Visual Studio Professional 2010 and the Team Foundation Server Express (beta). My VS Project (C#.Net / WPF) has been migrated from VS 2008 (without TFS) to VS 2010 (with TFS).
Whenever I apply changes to my code and try to debug my application, I get messages like This breakpoint will not be hit. (in german: Der Haltepunkt wird momentan nicht erreicht. Der Quellcode weist Unterschiede zur Originalversion auf.) and the project is started using the old executable version (the one with the last successful build). No errors occure, the code is OK, but the changes are not applied either.
When I manually cleanup and rebuild my project, everything works quite fine - but there has to be a fix for this issue?
Edit: I just added a new project to my VS solution and checked it in on the TFS Server. Using this new project the problem does not occure. Even when I add the same dependencies I used in the project mentioned above, the debugging and building of the new project works fine without the errors mentioned above.
Maybe this information helps you to lead me to a solution.
It's not clear whether existing answers are not sufficient. I can't know exactly what's causing your problem; but, I can detail some places this potentially comes up.
The first area that I commonly see this is when a project references an assembly directly. You can create a project that creates an assembly. Another project might use that assembly and you can reference by assembly directly (and not add a reference to the "project"). This disconnects VS from really knowing it needs to "build" that referenced assembly first and it will sometimes get out of sync with the debugging symbols (PDB). You can tell if a project has been referenced or an assembly has been referenced in the properties of the reference (expand References in Solution Explorer, right-click a reference, and select Properties). A referenced project will not have a Specific Version property, while an assembly reference will. You can sometimes also tell from Project\Project Dependencies. If you have a reference to an assembly generated by another project but that project isn't a dependency in Project Dependencies, it might be an assembly reference. To fix this, you can usually just delete the reference and add a reference to the project.
I've also find that sometimes breakpoints confuses the debugger. If I have many breakpoints or they've been kicking around a long time, the debugger sometimes does some weird things. If I delete all the existing break points (Debug/Delete all breakpoints) and re-apply them the debugger is usually much happier.
You can find the answer here. The assemblies might be in GAC or a project or some projects need to be rebuild to generate the pdb files again, which are used for debugging. If you don't choose to rebuild it might use the old pdb files.
My guess is that you are putting breaking points somewhere your program can't access them.
Ex:
const int x = 5;
if(this.x == 1)
//do sth <--- breakpoint here
If you are running a mixed mode application (unmanaged native C++ & managed C#), make sure to set Enable unmanaged code debugging in your C# application's Properties window.
You have to rebuild, there isn't an easier way around it.
The program database files (PDB) need to be recreated. You should also have your configuration setting set to debug.
Also the first answer to this question must be of help as well.
This happened to me when I started VS as an admin, and it also happened to me when the project is set to a different architecture than a DLL that I used in this project.
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
