I've used a few F/OSS libraries in my commercial application. As per their licenses, I am obligated to include their source codes along with my VS2008 application. This is my first time making a "real" commercial application, and I would appreciate some advice on how best to go about including their source codes.
I don't want to package them as zip files alongside my installed. I still want my installer to be a single file.
You can add a zip file of the third party source code as part of your installer.
As far as I know, there is no best-practice for distribution of open source code with applications that use them.
Which licenses are the libraries under? The GPL for one says that you can just supply an offer for any relevant source. Something like "this app uses library x which is licenced under the GPL, you can download the source from here or write to blah enclosing £x and your address"
