2. Click Add > New Item.
3. Select 'Application Manifest File' (Visual C# shown) and click Add.
   
   
4. Edit the app.manifest file. Scroll to the bottom of the app.manifest file and remove the comments from this section of XML:

   AFTER:
   
   

   Note:
   The <trustInfo �> and <compatibility �> boilerplate sections from the app.manifest can be deleted, unless they are needed for other purposes.

   
   
5. Save the edits.
6. Rebuild the project and run it.
   
   

   Note:
   Check 'Enable native code debugging' or the app.manifest is ignored when running in the debugger. 
   
   

   
   
7. The icons should now be displayed in the dialogs.
