Update MAUI to use Dot.Net 7 makes everything extremely slow

Question

I updated the .csproj file to use 7.0. When I did that running the emulator takes now about 5 mins to show. Using my phone takes even longer. There are no code changes.

I put breakpoints to show that the app is actually loading and they show and once the breakpoint is shown then the wait begins.

Ok so I put console.writes in to see what was going on and for those I got:

[DOTNET] ******************** init the app12:45:27.3111314
[DOTNET] ******************** main page construct12:45:37.8230713

[DOTNET] ******************** go to page12:45:40.7025474
[DOTNET] ******************** init the Scheduler view12:45:40.7034439
[DOTNET] ******************** init the Scheduler view12:45:40.8500713
[DOTNET] ******************** end of go to page12:45:40.8502941

[DOTNET] **************** get appointments12:45:43.6064273
[DOTNET] **************** get appointments done12:45:43.8353050

This shows that after the app is init it takes 16 seconds then it should show (it does show the splash)

I believe this is the problem, after the get appointment I get pages and pages (output window) of the following:

I ran using dot.net 6 and all those do not show so I believe that is the problem.

Any ideas?
