尝试获取程序包的当前版本会导致错误APPX1706和APPX1704

Question

I have some troubles with Windows.ApplicationModel.Package class.

When I try to add the reference to Windows.ApplicationModel or when I'm getting the current package, 17000+ errors appears.

How I try to get the current package :

var myPackage = Windows.ApplicationModel.Package.Current;

The kind of error I get :

error APPX1704: The file .winmd 'Windows.Foundation.UniversalApiContract.winmd' contains type 'Windows.Graphics.Effects.IGraphicsEffect'. The use of spacename Windows is reserved.

Or

error APPX1706: The .winmd file 'Windows.Foundation.UniversalApiContract.winmd' contains type 'Windows.Graphics.Effects.IGraphicsEffect' outside its root namespace 'Windows.Foundation.UniversalApiContract'. Make sure that all public types appear under a common root namespace that matches the output file name.

Is there a solution to this problem or a better way to get the current version ?

Answer 1

For the first problem I am a bit uncertain, but it is always good idea to reboot (ide, os, etc.), if this is not helping maybe reinstall the SDK, IDE. I know this is not complete answer, it is just from experience. The second error is saying that your namespaces are not consistent. It means that instead of having Example.Logic, Example.Domain, Example.Utils - you have something like Example.Logic, Test.Domain, Utils (inconsistency of namespaces).

Answer 2

I found the source of the issue, it was due to the structure of the solution.

Just like in a Xamarin application, we have a "Core" project that contains the application logic.

We tried to use some Windows app specific namespaces in these shared classes, instead of creating an interface in the Core project and implementing it in the UWP project.

Removing the line with the reference to the Windows.ApplicationModel.Package class from the core project and move it to the UWP project resolved the issue.

Sorry for the lack of information on the original post.
