Uno.Sdk (5.2 templates) only allows ApplicationDisplayVersion value 1.0

[BrianDT]

Current behavior

If ApplicationDisplayVersion is set to anything other than 1.0 the build will fail to resolve Uno and other references.

    <!-- Versions -->
    <ApplicationDisplayVersion>5.0.21</ApplicationDisplayVersion>
    <ApplicationVersion>1</ApplicationVersion>

Expected behavior

Should be the same as

    <ApplicationDisplayVersion>1.0</ApplicationDisplayVersion>
    <ApplicationVersion>1</ApplicationVersion>

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

Reproduce by creating a new solution and project from the Uno Platform App template and just change the ApplicationDisplayVersion.

Wait for all the dependencies to error and then build.

Workaround

Keep the ApplicationDisplayVersion as 1.0, however this becomes a significant issue when you need to release a new build of an existing product.

Works on UWP/WinUI

This is certainly strange. The Uno.Sdk doesn't actually handle this property at all, it's all the underlying Microsoft Sdk's for Android/iOS/MacCatalyst that handle this.

[jeromelaban]

The error is flagged in VS only, and is reported as follows :

error NU1105: Unable to read project information for 'UnoApp1': The property PackageVersion was expected to have a single 
value across all target frameworks, but instead had the following values: 1.0.0, 5.0.2

This would indicate that something is changing PackageVersion through the change of ApplicationDisplayVersion.

[jeromelaban]

This is likely caused by https://github.com/xamarin/xamarin-android/blob/98c10631d6bd67d6fab70ebab041abb47141daaf/src/Xamarin.Android.Build.Tasks/Microsoft.Android.Sdk/targets/Microsoft.Android.Sdk.DefaultProperties.targets#L132, which sets Version which likely sets PackageVersion as the fallback value.

We probably should be setting the same version for all app heads.

[mikernet]

Is there a workaround for this?

[jeromelaban]

@mikernet yes, you can set the Version property to the same value. This is what the fix will do.

[dansiegel]

@BrianDT @mikernet to get this working you can do the following:

1. Update your csproj with the following property to override the version of Uno.Resizetizer

   <PropertyGroup>
     <UnoResizetizerVersion>1.5.0-dev.78</UnoResizetizerVersion>
   </PropertyGroup>

2. Update your Package.appxmanifest.

   1. Identity -> Version change 1.0.0.0 to 0.0.0.0
   2. Identity -> Name change to $placeholder$ if you want it to use the ApplicationId property from MSBuild.

Note that if the Version is anything other than 0.0.0.0 it will not get replaced. If the ApplicationDisplayVersion and ApplicationVersion are missing as MSBuild properties it will result in the version 1.0.0.1 being applied to the Identity -> Version node.

[dansiegel]

The end to end support should now be available from the latest 5.3 dev build of the Uno.Templates from the Command Line. If you have any trouble you can take a look at the differences there. Note that the Package.appxmanifest has been cleaned up a lot (see unoplatform/uno.templates#692) and a number of properties/elements have simply been removed.
