In Maui 'InitializeComponent()' does not exist in the current context.

Intro (not must read)

  I use Visual Studio 2022LTS regularly . It happens to install Preview version, and the IDE says usualy "'InitializeComponent()' does not exist in the current context.". However, it also says

NETSDK1147    if you want to build this project, you need installing these workload wasi-experimental.  Run this command  for installing dotnet workload restore  .

 

  I translated error massages from Japanese to English that’s why  sentences is not accurate, But I searched and understand that means workload for Maui and SDK were not installed to my visual studio.
 I have tried  below solutions then errors purged, so I noted this page.
