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

[danielancines]

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.

@jfversluis - looks like this is a question about something you showed in a video from your channel. Any idea?

@danielancines - can you show what exactly you tried to add that didn't work? The repro you shared seems to have a fairly standard CSPROJ file, so I'm not sure if I'm missing something in the repro?

It looks like the version properties being set cause some extra targets to run thinking it's an application if you have set OutputType to Library.

You can condition these properties so they only build when your app is building as an 'app' for instance:

<PropertyGroup Condition="'$(OutputType)' != 'Library'">
		<!-- Display name -->
		<ApplicationTitle>Maui.UnitTestError</ApplicationTitle>

		<!-- App Identifier -->
		<ApplicationId>com.companyname.maui.unittesterror</ApplicationId>
		<ApplicationIdGuid>11484137-87ce-4a1b-9fe6-3af1e44f2049</ApplicationIdGuid>

		<!-- Versions -->
		<ApplicationDisplayVersion>1.5</ApplicationDisplayVersion>
		<ApplicationVersion>1</ApplicationVersion>
	</PropertyGroup>

@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.

@Redth Unfortunately dotnet restore still failing, I'm thinking that <ApplicationDisplayVersion>1.5</ApplicationDisplayVersion> ignores the condition and still getting the same issue,

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

Following what was asked on issue #6626, I ran using Project System Tools and got some errors. Logs attached.

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

@mattleibow I have the exact same issue, and the "easiest workaround" (or the other posted above) does nothing for me, I get the exact same failures for dotnet restore

Edit: After some crosschecking in the other linked issues, I think that the "fix" was just misspelled.
What seems to work for me is

<Version>$(ApplicationDisplayVersion)</Version>

instead of

<Version>$(ApplicationVersion)</Version>

@jonathanpeppers and you even mention that this is the property that really matters, not ApplicationVersion ?!

Edit2: After playing around with it from a dotnet new template, it seems it just purely depends on what was edited last.
whenever you change ONLY ApplicationDisplayVersion or ApplicationVersion, but not the other, and it is not the one set in $(ApplicationVersionOrApplicationDisplayVersion), dotnet restore will fail
