Maui Performance Issue while set Application.Current.Mainpage as My CustomPage

Question

In Maui, when we set MainPage using Application.Current.MainPage right? there while I set my custompage as MainPage its take around 15 to 30 seconds to initialize page in UI part, apart from the loading custompage

code for example:

Application.Current.MainPage = new mycustompage() // here its take around 15 to 30 seconds to render and loading in the UI..

and i tried with this too after initialize page and set as mainpage still have issue -->
CustomPage page = new CustomPage();
Application.Current.MainPage = page; // still have performance issue

It would be more helpful if this issue have any fix, Thanks in Advance

Answer 1

The performance issue you're experiencing when setting Application.Current.MainPage to your custom page could be due to several factors. Here are some potential causes and solutions to improve the performance:

1. Page Initialization Overhead

• Cause: If your custom page has complex UI elements, heavy data bindings, or resource-intensive operations (like large images, heavy layouts, or network calls), it might take longer to render.
• Solution: Optimize the UI by reducing unnecessary complexity. Consider lazy loading certain elements or delaying resource-heavy operations until after the page is displayed. For example, use placeholders for images or data that can load asynchronously.

2. Resource Dictionaries and Styles

• Cause: If your custom page uses multiple resource dictionaries, styles, or large amounts of XAML, these can slow down the page rendering.
• Solution: Minimize the use of large resource dictionaries or styles that are not essential. Consolidate or defer the loading of certain resources where possible.
