Let's suppose I have a Window Forms / Console Application C# project with some external references and references to other class library projects in the same solution too.
When I build the Window Form project, I want the referenced libraries be stored in a different location (eg: bin\Release\Libraries), and not in the same folder as the .exe.
Is it possible to do?
There are 2 parts of your question:
How to configure solutions to build assemblies/EXE into folders of your choice - this is configured through properties of the project in VS (project properties -> build -> output path). Also value of check "copy local" property on each reference.
How to load assemblies files from non-default locations (i.e. from your ...\Libraries folder) - you need to make changes to your app.config file to add this non-default paths to assembly search location ( http://support.microsoft.com/kb/837908 ).
Correct answers were given earlier. I'll just mention that there is a nuget package for this called PrettyBin.
Install it on your startup project. DLLs and XMLs will go to a lib folder and you'll have a working example of how it's done, if you won't to customize.
Set Reference path in project peoperties.
You can also specify where your compiled exe goes by specifying Output path in project peoperties.

Look under chapter "The VisualStudio Project Reference + Copy Local true option is evil!"
Yes it is possible, you'd do it in your msbuild script. While I can't give you an exact answer, look here at this question on SO Copy all files and folders using msbuild
