Modifying app.config file with Visual Studio Extension

Question

Hello, I am trying to create a Visual Studio Extension (either Add-In or VSPackage) that will do the following:

1) Find all selected projects in the current solution. 2) Obtain access to each project's app.config or web.config file and modify it.

I have been able to figure out step 1 for both an Add-In and a VSPackage. I haven't managed to figure out a way to do step 2). Does anyone have pointers to a blog / documentation that can help me complete step 2) ?

Also, which extensibility option would you recommend for such a project? An Add-In or a VSPackage?

Thanks,

Answer 1

Since you have the selected projects, why just don't check if project directory has web.config/app.config files and if they exist then edit them? They are just xml files.
