Solution Output Directory

The project that I'm currently working on is being developed by multiple teams where each team is responsible for different part of the project. They all have set up their own C# projects and solutions with configuration settings specific to their own needs. However, now we need to create another, global solution, which will combine and build all projects into the same output directory.
The problem that I have encountered though, is that I have found only one way to make all projects build into the same output directory - I need to modify configurations for all of them. That is what we would like to avoid. We would prefer that all these projects had no knowledge about this "global" solution. Each team must retain possibility to work just with their own sub-solution.
One possible workaround is to create a special configuration for all projects just for this "global" solution, but that could create extra problems since now you have to constantly sync this configuration settings with the regular one, used by that specific team. Last thing we want to do is to spend hours trying to figure out why something doesn't work when building under global solution just because of some check box that developers have checked in their configuration, but forgot to do so in the global configuration.
So, to simplify, we need some sort of output directory setting or post build event that would only be present when building from that global, all-inclusive solution. Is there any way to achieve this without changing something in projects configurations?
Update 1
Some extra details I guess I need to mention:
We need this global solution to be as close as possible to what the end user gets when he installs our application, since we intend to use it for debugging of the entire application when we need to figure out which part of the application isn't working before sending this bug to the team working on that part.
This means that when building under global solution, the output directory hierarchy should be the same as it would be in Program Files after installation, so that if, for example, we have Program Files/MyApplication/Addins folder which contains all the addins developed by different teams, we need the global solution to copy the binaries from addins projects and place them in the output directory accordingly.
The thing is, the team developing an addin doesn't necessary know that it is an addin and that it should be placed in that folder, so they cannot change their relative output directory to be build/bin/Debug/Addins.

The key here is that team is responsible for a deliverable. That deliverable is a collection of binaries. So the "global" solution ... or "product that uses the deliverables from teams" is interested in ensuring that all of the 'current deliverables' work together. That is, that you have a deliverable from the collaborative effort.
So this begs a few questions. Do the team deliver what they consider to be a 'release'. This may be automatic in the build system. If it builds and all tests pass then publish it.
What you are looking for is a team publishing or promoting a release. The source code is how you got there, the binaries are the result. Each team controls what binaries it considers to be a release (this may be automated by the build system).
Not exactly what you asked, but I hope it is the answer that leads to the right questions to give good results.

One very simple way would be to create the solution. Include all the projects and add a project (or more) to handle the global solution build tasks. The projects in the global solution should then have a reference to the projects they need and then let Visual Studio handle how to get the binaries from each project. They will (under normal circumstances) be copied to the output folder of the build project. So the project added specifically for the global build tasks would have a copy of all the referenced projects
Another way would be to create a global MSBuild script that references the rest of the build scripts. Each project is on it's own a MSBuild script
EDIT
From the comments it would seem that there are two categories of projects. One that needs building and one that does not.
For those that need building reference them as projects in the aggregating project for those that do not require building add them either as references or add the dll as resources.
Using the later change the property of the Build action to None and copy to output directory to Copy if newer
In both cases you now have all dll's in the output directory you can then have a post build action on the aggregating project moving the dlls that should be in a specific folder (ie not in the output folder)

Have a look at the practice of Continuous Integration and the usage of a Build Server with scripted builds. This is an indispensable instrument when developing different parts of an application as a team, and your problems are a great illustration of the reason why.

You've not mentioned if you use a Version Control system. I've found in practise that each developer maintains his/hers/their teams configuration and builds locally on there machine, since you don't check *.suo or *.user files most of the personal configuration only affects the individual team member.
On a completely seperate machine check-out the same code from all repositories and compile the project on the build machine (this can be completely automated). This maintains your build servers independance.
Don't worry about it being a "Solution". You can easily build multiple solutions one after the other.
Since the output path is relative (and probably "bin\Debug") it'll get built wherever you check it out to. If you want all the binaries in the same output folder you could tweak the output path on every configuration to match. Something like "....\bin\Debug" (obviously this affects where the projects get built to on the local machines but it might not matter). That way multiple projects would get built the same target output.
You could also include a seperate setup build on the build server which isn't on each developers local machine to package up the final product.

Does documentation for file Microsoft.CSharp.targets with default C# targets exist?

When I create C# project in Visual Studio 2010, file Microsoft.CSharp.targets is included.
Is any documentation available for it?
Which targets in it, which properties are used?
It is especially useful when editing build script manually without VS.
The file with targets could be investigated manually (what I do from time to time).
But in such case it is not clear what is a matter of changes, what is by specification and what is no.
Everytime I need something about Microsoft.CSharp.targets I found it in different places.
I have not found "one place" with all described.
Does complete reference available?
Thanks.

No specific documentation I know of, it is an implementation detail for C# projects. You can find plenty of documentation about MSBuild in the MSDN library, the Microsoft.CSharp.targets file just contains targets that are specific to building a C# project.
The most important targets it implements are Build, Clean and Rebuild. They directly correspond to the commands you find in the VS build menu. The .csproj file merely sets properties that affect the outcome of the general targets. All of this is readily available on your machine, you can look at .targets files with an editor. There's just a whole lot of it and it is isn't exactly that easy to read, the concept of XML as a programming language is a bit, well, flawed. No debugger either.

Where do you put your 3rd party libraries?

I've got a bunch of .dll assemblies, such as HtmlAgilityPack and MoreLinq. Where am I supposed to put these files? I usually toss them somewhere in my Projects folder, but then I'm always digging around for them. Is there a standard place to put them?

There's no standard place to put them, but make sure you:
Put them in one place
Include them in source control.
I put all my required dll's in a top level directory in my solution called "Dependencies", parallel to the project folders. I have them in source control such that when new developers check out the solution, it all compiles and works right off. It's the only way to go.
I include only the .dll files absolutely needed. This keeps it light, which is good, but then when I find some other part of MVC Contrib or whatever that I need, I have to go find the unzipped directory, which might not even be on my computer! Others put entire library directories (readme.txt and all) as part of their source control linked to the solution. This ensures you and future developers will have everything they need, but adds a little dead weight. Either is a good strategy.

Having a "Lib" folder at the same level as source projects is a common way.
To be honest, it's not the dependencies my projects have that I find hard to manage, it's the dependencies the dependencies have. I'd just like to mention NHibernate, Castle Windsor and the various Castle Windsor Facilities in particular. Getting all of those to play together on my last project cost me a lot of time.
For open source projects, I also like to have the source code handy because sometimes its useful to debug into the source code. (And sometimes because the documentation is so poor, you have to read the source code to find out how it works). I've seen VS projects arranged so that the project references the DLL yet at the same time, VS knows where to find the source code, as I write I can't quite remember how to do that.
So, a Lib folder for DLLs works for me; I often call it "Shared Dependencies".
As for open-source source code, I don't have a standard way to version that because each project is structured differently and has a different build process. I don't like to tinker with the open-source project structure or build method because then, I take responsibility for it. If for some reason, it won't build, or builds incorrectly, or produces a faulty DLL, the cause would be exceedingly difficult to track down, and I'd have to get deep into troubleshooting all of that which I dont care about at all.

In a folder UNDER your solution directory, e.g. "external" or "library". That way your continuous integration system (or other team members) can do a pull of one root from your source control system and have everything they need.
In SVN, use svn:externals to pull that directory from a different root so you can easily share library DLLS (and library projects) between solutions.

In the office we have a share on the network for referenced asseblies. These could be 3rd party or assemblies of our own that could be shared between projects.
I also, don't like the idea of putting the dll files in source control. If all the developers have access to the share all will work fine.

The visual studio directory in My Documents seems like a logical place to put them. I don't know if it's the best or anything wrong with it but at least all the libraries are found in one place.
%USERPROFILE%\My Documents\Visual Studio XXXX\Libraries

At my company we place all our shared DLL assemblies onto a network drive in a folder called Assemblies. From there, we use SyncToy to mirror changes between that folder and a folder on our local development machines (in my case C:\Assemblies with subfolders for different versions or useful third party assemblies). Using the "Reference Paths" feature of Visual Studio projects makes it very easy to select different assembly versions based only on locations.
For projects at home, I would definitely go with the idea mentioned by Jeff M of placing them in the Visual Studio folder under My Documents.

I don't have a hard and fast rule on the location. However, I would encourage consistency!
For example, I needed to to this for a small tool I'm writing for a client at the moment, so I checked their other code bases in Bitbucket which seemed to use a dependencies folder in the solution folder (alongside the other projects), so I copied that.

Moving projects files in a .NET project

It's not code-related but IDE related. I'm working on a .NET solution with about 35 different projects. These projects need to be re-organized into a new folder structure. Why? Because about 10 of those will be removed and the rest will be divided in more logical units.
One way to do this is by creating a new solution, Drag&Drop the projects into a new folder tree within the Windows explorer and then just add them to the new solution.
To be honest, that sounds dumb!
Is there a way to just move projects into different folders from within the IDE? I've tried to "save as" the projects but the IDE won't accept a different folder.
It's irritating but because there have been a few wrong choices in folder names, I'm now stuck with those names.
Example: Right now I have a project main folder which contains child folders named "Client", "Server", "Business", "Database" and whatever more. Within those child folders, there are more child folders, each a three-digit number. Within each numbered folder there's a project which is named in some logical way, like Company.Business.Customers with additional logic within this project.
The problem is that not all projects now follow this naming convention and I consider it obsolete.
A project like Company.Business.Customers should just be in a folder named Company.Business.Customers in the project root so it's easier to recognize. The name already makes it clear that it's a business class for this project. The clear division within client classes, business classes and whatever more just needs to be arranged within the solution, but I want to flatten the file structure. (And remove some obsolete projects.) Basically, I'm not refactoring, I'm just cleaning up.
VS2008 doesn't seem to have such an option, though...

Fire up notepad.exe and open the .sln file. And start Windows Explorer, navigate to the solution directory. Observe how the .sln file content matches the solution structure. Edit the entries, make the corresponding change with Explorer. Backup first.

I don't think there's an easy answer here. Your main problem is going to be that Visual Studio (or .NET) doesn't care if you have classes that belong to a different root namespace sitting in a project.
So if you have a project called Project.BusinessObjects and another project called Project.DataObjects there is nothing stopping you from putting a class called Project.BusinessObjects.User into the Project.DataObjects project.
I don't know of any way of doing all of this without a lot of manual work. Resharper will help quite a bit if you use the 'namespace rename' feature, but you're still gonna end up with a lot of grunt work.

Also, be VERY wary of doing this in conjunction with version control systems. You have to know your version control system really well to know how it's going to react to such major refactoring.
Other than that, what you are describing doing is not all that difficult. You do have to edit the solution files and maybe the project files by hand, and you might need to remove a project from a solution and add it again when it's under the right directory.
I would make a backup, and then refactor away. I think it is a mistake to think that you can do everything you need from the IDE, though. And if you do what you describe from the IDE in a source control system that uses the old Visual SourceSafe API, you will certianly (guaranteed) mess up your bindings, that API is just not made for moving (or renaming, for that matter) files around in the way you describe. The best way to do this under that scenario is to remove all source control bindings and then re-add the reorganized solution back in.
It's not that difficult, you just have to prepare (do a backup) and experiment until you get it right.

I don't think there's any way to do this from within Visual Studio, and as #gmagana points out it's going to be very difficult to do if the files are under version control.
However, it is possible to do it manually.
Start by creating the new, desired folder structure - ignore the .csproj files and solution files for now, and more the .cs files you're interested in into the new structure.
Now, fire up Visual Studio, and create a new, empty project. If you have different types of projects, you might want to create one new, empty project for each type. This will leave you with an empty .csproj file, and a .sln file with just one project.
Copy the empty project file to where they're needed, and rename them as needed. You can edit them and change the Assembly name and default namespace if you want, or wait until you're done and change the settings with Visual Studio.
Finally, edit the .sln file, and remove the Project section. Copy the empty .sln file to where you want it, and open it up in Visual Studio. Now go and add each of your existing projects to the new solution.
Within each project, click the "show all" button, and start including all the files you've copied into the project structure. Resolve missing dependencies, change the namespaces and assembly names for the project, and make sure that the code files don't specify a namespace you don't want. Repeat until done.
Once you get the new solution to build, it will be helpful to open up the DLLs in Reflector in order to ensure that you haven't missed any namespace declarations in the code file - if you're trying to get to a point where there's a 1-1 correspondence between the DLL and the namespace, or even ensuring that no namespaces are split between DLLs, Reflector is your friend.
Good luck.

I've used the following solution to solve my problem:
I started with a new, empty solution in a new folder.
For every project that needed to be moved, I used the Windows explorer to create a child folder in the solution folder, this time with the proper name.
I copied the projects from their original location to their new folders.
I added all the (moved) existing projects from their new locations.
In the Solution Manager, I renamed the projects to a better name.
I fixed the project properties and other settings for all projects.
This did clean up the whole project quite nicely. I then added the whole project to Vault (Version Control System) and once it was in the VSS, I deleted the folder again (actually, just renamed it first) and retrieved it back from the VSS system so any obsolete binaries and other garbage was gone too.
It's a lot of work, but the result turned out exactly what it needed.

packaging vs2005 project

Here are the steps I take to create a package shipped to the end users:
Use visual studio 2005 Build the project (which is library DLL written in C#), both in debug and release mode.
I run doxygen and create documentation
I create a folder structure where I put my dll documentation and some release notes
zip it
ship it
the directory tree structure looks like this:
--NetApi:
--Api
--vs2005
--relesae
--dll
--debug
--dll
--documentation
--htmls files generated by doxygen
--ReleaseNotes.html
--Examples
I am thinking of rolling out a script to automate that. But before I do that, I would like to find out the common practices of packaging library api type of project, particularly structure, and tools used. References and examples are highly appreciated
Thanks

I am a big believer in continuous-integration and automated builds.
We have a rule in our shop that we never, ever, ever provide deliverables to a customer that were not produced by a fully automated, zero or one step build (that means that it took no more than 1 mouse click by a human to baseline, build, package, and release the thing.) These fully automated, one-step builds work by recognizing when a change is made to your source code control system, and automatically triggering the "build script."
For C#, I can recommend both CruiseControl.NET and Hudson.
I can also recommend the Pragmatic Project Automation series of books. Variants of this title should be available for both Java and .NET.
There are lots of prewritten build servers out there that can help you automate this.

For deployment I really like Inno Setup.
It is free, flexible, and can be easily customized to your tastes.
