I am having issues with Hot Reload. It does load just fine. But it fails on execution.
I am using Microsoft Visual Studio Community 2022 (64-bit) - Current
Version 17.1.6
Here is what I see in the Xamarin Hot Reload Output window when I save the page.
[8:49:20 AM] (MSTCEvents.Android) Legacy Xamarin Project does reference Xamarin.Forms.
[8:49:22 AM] (MSTCEvents.Android) XAML Hot Reload is using 'full page' mode

at System.Threading.Tasks.Task.Execute()<---
The file does exist where Hot Reload is looking. C:\MSTC_GIT\Misc\MstcEventsMobleApp\MSTCEvents\MSTCEvents\MainPage.xaml
The only reference I could find to this issue is here
I deleted the .vs directories and that did not seem to help.

Anonymous2022-05-04T07:17:09.903+00:00 Can you move your project to other disk, then make a test?
I notice you use the latest V17.1.6, Is that running normally in previous version? -

Thanks for the quick response .
I moved the project to a network share and still had the same issue.
I was having this issue with Microsoft Visual Studio Professional 2019 Version 16.11.13. That is why I upgraded to the most current VS2022.
I also tried this morning giving full control on the project directory to everyone to see if it was some sort of security issue. Unfortunately that did not help.

2022-05-05T17:36:54.717+00:00 Thanks so much for all your help. This is my linker setting.
As to the link you sent, I have done all that. I upgraded the version of Xamarin.Forms to
and as you can see in the original post, Hot Reload is connected and ready.
I am always the lucky one ........
cheers
