Net7 Maui Unable to load DLL 'Microsoft.ui.xaml.dll'

Question

In Visual Studio, using Net7, when debugging project it runs fine. If I go to the directory and run the exe I get the following message in application log "Exception Info: System.DllNotFoundException: Unable to load DLL 'Microsoft.ui.xaml.dll' or one of its dependencies: The specified module could not be found. (0x8007007E)". When researching the problem it seems to be common issue but none of the solutions work.

Hello,

Right now, it's not supported run the exe file in bin folder directly, you may can run the exe with WPF or other projects but not with MAUI/WinUI projects. Please refer to this doc- Debugging on Windows - .NET MAUI | Microsoft Learn to debug your app.

Besides, running exe's in MAIX packages is also not supported. It's only supported publishing to an MSIX and running it that way.
