Question

I created a new template, which I can use. However it only uses some project settings

I made a project with a working libSDL hi world example. I exported as a template, but template doesn’t save some of my settings: ( It ‘saves’ them, but new projects ignore them. )

Ignored settings:

include header folders:
    for .h files
    for .lib files
linker args: SDLmain.lib SDL.lib
windows subsystem: /SUBSYSTEM:WINDOWS

Here’s the saved /template/sdl/sdl.vcxproj file, and the settings actually appear in it yet they are ignored.

Answer 1

It’s likely that the project system is actually removing these items as the file is being created: when you create a new project, Visual Studio runs a wizard in the background which can affect what actually ends up in the newly-created .vcxproj file.

These wizards are specific to the project type so you can actually supply your own via the <WizardExtension> element in the .vstemplate file. Of course by overriding the project creation logic, you may lose certain functionality/behaviour (unless there’s a way of inheriting the original wizard’s base assembly).

Alternately, a solution which I’ve used in the past is to create a VSPackage which handles the SolutionEvents_ProjectAdded method (in DTE.SolutionEvents). This method gets called whenever a new project is created or added to the solution, so you could potentially use that to set your project up as needed.

Note that you would need a way to ensure that it only affects projects of your specific type; a flag in the .vcxproj template file would do this.
