`The value "/**/*" of the "Include" attribute in element <ItemGroup> in file .nuget\packages\uno.sdk\5.2.161\targets\Uno.SingleProject.Desktop.targets`

Current behavior

Build error with:

The value "/**/*" of the "Include" attribute in element <ItemGroup> in 
file ".nuget\packages\uno.sdk\5.2.161\targets\Uno.SingleProject.Desktop.targets (33,25)" is a wildcard 
that results in enumerating all files on the drive, which was likely not intended. Check that referenced 
properties are always defined and that the project and current working directory are not at the drive root.

Expected behavior

Restore works

How to reproduce it (as minimally and precisely as possible)

No response

Workaround

Go to Uno.SingleProject.Desktop.targets file and modify lines https://github.com/unoplatform/uno/blob/57abfeaad51a495fa7512a19eec407bf77cd0739/src/Uno.Sdk/targets/Uno.SingleProject.Desktop.targets#L33-L34

to remove the forward slashes

Works on UWP/WinUI

Anything else we need to know?

https://github.com/unoplatform/uno/blob/57abfeaad51a495fa7512a19eec407bf77cd0739/src/Uno.Sdk/targets/Uno.Common.targets#L53 already contains a slash

Thanks for the report. Can you provide a repro?

[xperiandri]

Unless I give you my production solution I have no idea how to reproduce it. But, even so, the leading slash in those MSBuild properties is definitely wrong. As if the variable becomes "" it will do very wrong things

[jeromelaban]

Why would DesktopProjectFolder be empty? Are you changing its value explicitly?

[xperiandri]

Hypothetically. I just deducting why MS never prepened paths with slash but append variables

[xperiandri]

Really I don't know how this error appeared but it had…

[jeromelaban]

If the path is empty, this will cause all sorts of other issues, such as including all files from the root of the project, which is not the intent of that line. If you can provide a binlog of the issue, it will still help.

Here it is desktop.zip

Thanks. This is a very curious behavior and feels very familiar to https://github.com/dotnet/msbuild/issues/9351. Could you try moving your project to a very small path and see if it reproduces?
