Application in Break Mode

srfpala 111

Using VS2022 Community Edition Win10 64 bit on a WinUI 3 Project
Code compiles clean and Rebuild Succeeds
Execution goes into Break mode with this error
System.DllNotFoundException: 'Unable to load DLL 'Microsoft.ui.xaml.dll' or one of its dependencies: The specified module could not be found. (0x8007007E)'

----------------------------------------------------------------------------

But Microsoft.ui.xaml.dll was downloaded and copied into
C:\Windows\SysWOW64 and into C:\Windows\System32

Any ideas as to what I should do ?

You must not do that.
Microsoft.ui.xaml.dll is installed with the Windows App SDK Runtimes (downloads)
and has many dependencies

I think I should remove Windows-App SDK using Powershell and then run
WindowsAppRuntimeInstall then
WindowsAppSDK.Cs.Extension..Standalone

Suggestions ?

Is the problem resolved after installing Windows App SDK Runtimes?

Downloaded 1.1 Installer (x64)
Ran WindowsAppRuntimeInstall.exe Which launched and
may have run within a DOS window – some statements appeared and the DOS window disappeared leaving no messages.
This may be normal….. but seems strange.
How would I know that it is correctly installed ???
Is there a test I can run ?

You can look this one Check for installed versions of the Windows App SDK runtime

Open a PowerShell window and run one of the following commands.

# For 1.0 Stable and Preview releases and later get-appxpackage *appruntime* # For shorter output displaying only PackageFullName (get-appxpackage micro*win*appruntime*).packagefullname # For 1.0 Experimental get-appxpackage *WindowsAppSDK* # For version 0.8 get-appxpackage *reunion*
