Dotnet restore fails when ApplicationDisplayVersion has some values to configure Unit Test for MAUI

Description

Following links like https://www.youtube.com/watch?v=C9vIDLQwc7M&t=449s to configure xUnit Tests on my Maui App, I’m having problems to add net7.0 as a TargetFrameworks and add a condition to OutputType as Library to able xUnit Project test my classes.

dotnet restore fails when I add <ApplicationDisplayVersion>1.5.0</ApplicationDisplayVersion> 1.5.0 or 1.5 for the ApplicationDisplayVersion, if the value is 1.0.0 doens’t occurs. This is the error:

  "logs": [
    {
      "code": "NU1105",
      "level": "Error",
      "message": "Unable to read project information for 'Maui.UnitTestError': Sequence contains more than one element"
    }

I’ve been testing this for days and I figure it out that the ApplicationDisplayVersion is the problem, but I don’t have ideia why.

Steps to Reproduce

1. Create a MAUI project
2. Add net7.0 as a TargetFrameworks option: <TargetFrameworks>net7.0;net7.0-android;net7.0-ios;net7.0-maccatalyst</TargetFrameworks>
3. Go to <ApplicationDisplayVersion>1.0</ApplicationDisplayVersion> and change the version to 1.5 or 1.5.0
4. Try to restore packages: dotnet restore
5. Restore will fail and the file project.assets.json in obj folder will show the log error above.

For now the easiest workaround is to add <Version>$(ApplicationVersion)</Version> in your project directly after your <ApplicationVersion>1.0</ApplicationVersion> property.

@Eilon I only changed the ApplicationDisplayVersion to 1.0.5 and the command dotnet restore, just that. I’ll try what @Redth wrote above and let you guys know.

Thanks.
