I have read the publishing profiles have replaced WDP
but I cannot find decent tutorial
how to add and modify pubxml file to my project
any
When you right-click a project and select Publish, you get the Publish Web wizard. Using this to create a profile (you don't have to actually publish in order to create a profile) creates the .pubxml, and on the first step of the wizard you can use the Manage Profiles button to rename or delete profiles. Profiles are created in a PublishProfiles folder under Properties. See
