Answer 1

The sequence of steps given by Nasreddine will add a manifest file, into your project.

There is another way to add a manifest. Right click project > properties > Application tab > View Windows Settings This will bring up the default manifest, which you can edit. I am using visual studio 2010 Express. From other reading the method should be similar.

For a project that uses non-windows components (I program in ESRI arc-objcets with VB.Net) there seems to be no way of adding a manifest file. The View Windows Settings button is disabled. The steps given by Nasreddine do add a Manifest file which can be edited but this cannot be incorporated into the project. I have tried many tricks: like adding as a resource (embedded and not embedded), adding it the obj > debug folder.

The kicker test was I set up a pure windows project, got a windo button comand to return the correct version string (after adding a manifest) then tried to add an non-windows component (ESRI Addin). this failed with an error message.

I am was just trying to identify the OS because the file location of required files is dependent on operating system. Hope this save others from going down this rabbit hole.
