XML parsing errors when manually converting app from Xamarin to Maui

I am manually converting my Xamarin app to Maui. After fixing all the conversion errors, I am left with these 16 errors that I do not know how to resolve.

I replaced the app name with xxxxxxx

Any help would be appreciated

Hi, I'm experiencing the same problem
after including all the files from my old Forms projects to a newly created maui solution, cannot get rid of this error:

1>CSC : error MAUIG1001: An error occured while parsing Xaml: Root element is missing..
1>CSC : error MAUIG1001: An error occured while parsing Xaml: Root element is missing..

Don't know what to do, I fixed everything from the refactorization but I cannot continue. I followed all the guides, I think I have it all as expected.
Not any clue how to fix it, neither in the warnings nor in the output of the build

my target framewoks in the csproj are like this

	<TargetFrameworks>net6.0-android;net6.0-ios</TargetFrameworks>

Hi, recently I found the reason of this error and could solve it

It's exactly what it says, a xaml is wrong, the real problem was finding which file is wrong over 30 xaml files checking manually one by one!
Finally it turns out that during the raw refactoring battle, a xaml file had the root node commented, that was all :(

a lot of time could be saved if the error message included the offending file name

Answer 3

As stated above, the issue in XAML file, but not the project file, but it could be into any of your XAML file.

I had this UserLogin.xaml, and while editing I accidentally press 0 at the starting of the file.

Had to manually check all the XAML files, and then found this issue.

I am also having this same issue. Has any fix been discovered for this?
