Maui Build and render in emulator much slow

[Vikas8881]

Description

Yesterday I start a new project in Maui. It takes time to launch in the emulator. 

then I see Hot Reload not working in the emulator. then I use debug. fine

but today it crossed limits just to view the app design I run the app and boom emulator is blank I wait and wait for its just a single page register page with 1 image, 3,4 label's and 1 button without any functionality.

I make a video for evidence because I see the Microsoft maui team not taking serious developers' comments. 

Visual Studio Microsoft Visual Studio Community 2022 (64-bit) - Current Version 17.5.1

here is the link below

Steps to Reproduce

1. Create the App. Dotnet Maui
2. Run the app in android Emulator with the default template.
3. Create a simple registration Page using the default image of dotnet bot and some 2,3 labels and 1 button. because I am a beginner so I do have not much experience in xaml design and I try to check hows it looks. now after changing the default AppShell to Custom Page Register Page.
4. Then Run the App it takes 10 minutes to launch. then I make some changes in xaml code for UI. I see hot reload does not work.
5. Fine I restart the App. then I stop the application and resume the same project after few hours and it took 30 minutes to launch the app in the emulator I know the Microsoft team will not believe so I make a video on it showing the configuration of the system.

I'm curious as to why you would say this. We take every report very serious.

i said because of many peoples want xaml desginer. because its very painfull for just view app desgin with hot reload and last time when i see you closed the ticket without any solution hot reload is a Nice feature yes it it but its cant take desginer place. according to me i am work in visual studio from the last 5 year's. But now more painfull for me what i show in video Build run and deploy and response 0 i can't see result emulator i try same thing in window machine there its work. and i use serious word because i want Microsoft team understand the our problem and give us solution or alternative. if its hurt you then sorry

The star of the emulator and build may be slow depending on your hardware and/or other running applications. However, if the deployment and running is the slow part, do you have Hyper-V or HAXM enabled?

Have a look at this doc and see if you are running in the fast path: https://learn.microsoft.com/en-us/dotnet/maui/android/emulator/troubleshooting?view=net-maui-7.0#performance-issues

1. i see your video, your emulator is slow to start. Do you try only start emulator and not build project? or use Windows subsystem for android
2. wpf designer only show ui control of windows, Maui is for crossplatform and use control of platform, use hotreload is better. In my experience, Maui build windows app is faster than android and ios, so if you build app is slow when for android, you can try build it for windows.

I start the Emulator, Build the Project, Clear the auto generated File's rebuild etc i try all the thing's then i decide report here.

But yesterday i connect my Android Device using USB and it's work fine. maybe this issue with only virtual emulator. @xtuzy yes you are Right working on Windows Platform as expected. this issue happens with Android & IOS not Tested yet so i have no idea about IOS
