Make sure that you are able to deploy for the target architecture (e.g. that you have configured an android emulator or that you have an android phone connected with developer options and USB debugging enabled if you try to debug the android target) – Shellishellie

I'm having this same issue. Not sure why, I've gotten other .NET MAUI apps to work before, but it won't run new ones. – Lurlenelurline

I had to start the project from its raw path on the hard drive rather than a mapped network drive in order to get past this error. – Halfpint

In my case, I ran into it when the solution contained two projects. Two different .csproj-files targeting all 3 platforms. After I deleted all but the one project I wished to run, it started working. – Vu

UPD: also I got into a case where the .csproj file somehow contained another solution file. Deleted that and again resolved the error. Maybe that'll help. – Vu

If you have this issue and nothing seems to fix it, you might want to try what helped me. It turned out that the error message had nothing to do with the real problem. What was the real problem for me? My PC was not allowing location services nor apps to used if enabled. Make sure you go to settings and enable this. – Manthei

Answer 1

What worked for me was renamed this tag.

<!-- App Identifier -->
<ApplicationId>com.companyname.my_app_name</ApplicationId>

To

<!-- App Identifier -->
<ApplicationId>com.companyname.myappname</ApplicationId>

Without underscore.

Thanks for the solution. It worked and solved the seam issue I have encountered today. – Cachalot

Don't forget to vote. :p – Grimes

Thanks for the solution. Gave it a thumbs up. Also, you may have to rebuild your application after the change, its sounds intuitive, but in my app after I made the change, it still didnt work, then I rebuilt the app and it worked. I guess maybe also because I have a reference to a library project maybe. Thanks so much – Stative

Answer 2

Please try to right click your solution -> Configuration Manager,

then pop up the Configuration Manager dialog, please enable the Deploy option.

For example:

Hermaphrodite

I tick the deploy option in the configuration manager still i get the issue – Submerged

You can try to delete the obj and bin folders and rebuild it. – Hermaphrodite

I have this problem with .NET8. "Deploy" was already checked, closing VS and deleting bin/obj yields two new errors: NETSDK1005 and XA1018 -- and I haven't changed the Windows or Android build targets. The number of bugs in MAUI is staggering. – Isidroisinglass

Answer 3

I had this error when I used a space in my solution and project: 'my solution'. I deleted the solution and created a new one with a name without spaces: 'mysolution' and it worked fine!

Answer 4

I had the same problem and finally realized that there should not be any underline character in the project title.

Answer 5

In my case, turning on Developer Mode in Windows Setting & restarting Visual Studio worked for me:

Airt

I had to also delete the obj and bin folder. Cleaned the solution as well. Then it worked. – Cyclops

Answer 6

Close your vs and delete the hidden folder ".vs" at the root of your solution.

Answer 7

I ran into this problem when my App Identifier was greater than 50 characters.

I changed it in my app's csproj

<!-- App Identifier -->
<ApplicationId>THIS MUST BE LESS THAN 50 CHARS</ApplicationId>

Answer 8

I'm on Windows 11 Home, this worked for me:

Enable developer mode.
Backup project files.
Close and delete the existing project.
Create a new project.
Restore backup.

Polenta

After enabling developer mode you should be able to delete the obj and bin folders and then be good to go. I also did a clean solution as well. – Cyclops

Answer 9

Was facing this issue when trying to build from local, changing this option helped me

Answer 10

In my case it was the HardDrive Filesystem the project was stored on. It has to be NTFS, extFat does not work for certain .Net Projects incl. .Net Maui.

Answer 11

This is still a problem in Microsoft Visual Studio Enterprise 2022 (64-bit) - Current Version 17.9.2

I found the remedy to be an update in my Maui app .proj file. If you have:

<WindowsPackageType>None</WindowsPackageType>

change it to:

<WindowsPackageType>MSIX</WindowsPackageType>

And no other changes are necessary.
