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

None

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.
