Describe the bug

After updating to v1.4-preview2 and returning to the previous version (v1.3.3), we get the following error

APPX1101	Payload contains two or more files with the same destination path 'Microsoft.WindowsAppRuntime.Bootstrap.dll'. Source files: 
net7.0-windows10.0.19041.0\win10-x64\MsixContent\Microsoft.WindowsAppRuntime.Bootstrap.dll

.nuget\packages\microsoft.windowsappsdk\1.3.230724000\runtimes\win10-x64\native\Microsoft.WindowsAppRuntime.Bootstrap.dll	.nuget\packages\microsoft.windowsappsdk\1.3.230724000\buildTransitive\Microsoft.Build.Msix.Packaging.targets

We need to close and reopen Visual Studio and remove bin and obj folder to solve the problem

Same here, clear obj & bin folder works for me

I just had this happen too - the same build error, when I reverted to v1.3.230602002 from v1.4.231115000.

Explicitly selecting "Clean" from the Build menu of Visual Studio 2022 v17.8.2 did not help - the build error remained.

Deleting the bin and obj folders did work. Many thanks for posting your workaround, @ghost1372.

Sometimes we need to revert to older versions, e.g. in my case I needed to recreate a customer's situation who is using an older version of our app. Yes, the workaround is easy to perform but it took a while to discover it, and will affect other devs too, presumably.
