VS Setup Project Will Not Ship With Future Versions of VS
In the past I wrote about Visual Studio Setup Project and how you use it for your software deployment – Extending Visual Studio Setup Project
But now Microsoft decide to remove the support from VS Setup Project and invest more in WiX.
“Future versions of Visual Studio will not include the Visual Studio Installer project templates.
To preserve existing customer investments in Visual Studio Installer projects, Microsoft will continue to support the Visual Studio Installer projects that shipped with Visual Studio 2010 per the product life-cycle strategy.”
So if you are using VS Setup Project you still have couple of year to use it but start think about moving to WiX.
