at HydroDesktop.MainApplication.Program.Main(String[] args)

Start by reproducing the startup failure and reading DotSpatial.Controls.AppManager.LoadExtensions, then follow the stack trace through HydroDesktop.MainApplication.MainForm and Program.Main. Check the Application Extensions directory for the missing DotSpatial.Plugins.ExtensionManager assembly or dependency. Done means the application starts without this CompositionException and the extension-loading path is covered by the relevant validation.
