ThemesOfficeThemeCatalogRegistrar.Register is slow - WPF Studio, Themes, and Shared Library for WPF Forum

Platform: .NET 4.7

Environment: Windows 7 (64-bit)

I call ThemesOfficeThemeCatalogRegistrar.Register() in my application's startup. I am supposed to do that, right? I was trying to pin point some slowness in app startup, and I realized that this call takes almost 500 milliseconds. Can it possibly be optimized? Thanks.

Hi Jim,

That method call is effectively just putting XAML resource dictionaries in your Application.Resources. When I step over that line in our sample app, it goes much faster (< 1ms). But note we also wrap all our ThemeManager setup in ThemeManager.BeginUpdate()/EndUpdate() calls. Are you doing that in your startup as well? That will help prevent additional updates before you've completed all your ThemeManager configuration.
