    Did you change anything with regards to your Windows SDK installation? Do you have "Windows.Foundation.UniversalApiContract.winmd" somewhere under C:\Program Files (x86)\Windows Kits\10\References?

    Did you change anything with regards to your Windows SDK installation? You used to be able to build before, right? Are you able to create and build empty UWP apps from Visual Studio?

    Tautvydas-Zilys,

    Here too :
    C:\Program Files (x86)\Windows Kits\10\References\10.0.16299.0\Windows.Foundation.UniversalApiContract\5.0.0.0

    I tried to compile for all versions of sdk, modifying the target API (4.6) always the same error. If I try with a new project (uwp) the compilation is ok, but not with my current project.
    Compilation stops to restore nuget packages.

    Greetings.

    Yeah, this is unsupported. You'll have to set that version to 5.0.0 in order for it to start working again.

    Tautvydas-Zilys,

    I also thought that was the problem but the error remained after downgrade the version (6.0.8 > 5.0.0) in the package manager.
    In fact the problem comes from a new scipt (i implement an online mode for the game), if i put it in comment before compilation it compiles, just have to uncomment before publishing on the store :
    Code (CSharp):
    1.  
    2.  
    3. #if WINDOWS_UWP && !UNITY_EDITOR
    4.  using Windows.Networking.Connectivity;
    5.  using Windows.Networking;
    6. #endif
    7.  
    8. #if WINDOWS_UWP && !UNITY_EDITOR
    9.  public static string GetLocalIp(HostNameType hostNameType = HostNameType.Ipv4)
    10.         {
    11.             var icp = NetworkInformation.GetInternetConnectionProfile();
    12.  
    13.             if (icp?.NetworkAdapter == null) return null;
    14.             var hostname =
    15.                 NetworkInformation.GetHostNames()
    16.                     .FirstOrDefault(
    17.                         hn =>
    18.                             hn.Type == hostNameType &&
    19.                             hn.IPInformation?.NetworkAdapter != null &&
    20.                             hn.IPInformation.NetworkAdapter.NetworkAdapterId == icp.NetworkAdapter.NetworkAdapterId);
    21.  
    22.             return hostname?.CanonicalName;
    23.         }
    24. #endif
    25. //////////////////////////////////////////////////////////////////////
    26. void AddHostToBDD(string data)
    27. {
    28.     string localAdress;
    29.  
    30. #if WINDOWS_UWP && !UNITY_EDITOR
    31.             localAdress = GetLocalIp();
    32. #else
    33.             localAdress = Network.player.ipAddress;
    34. #endif
    35.  
    36. ...
    37. }
    38. ////////////////////////////////////////////////////////////////////////////////////////
    39.  
    In any case I still do not know why.
    Thanks for your help.

    Greetings.

    Can we get a bug report on this? I don't think this is a known issue.

    @Tautvydas-Zilys we are getting the same error when trying to build for hololens and this is completely stopping our development. Tried multiple versions of unity but same issue about UNetWeaver across the board. It is very irritating that this error causes all our scripts not to compile because we have no way of fixing an error in unity itself.

    Can we please get a timescale on the fix for this, as we are using the latest officially supported version of unity and do not expect long standing issues such as this to still be making it into builds. Going through issuetracker shows this issue has existed for a long time and continues to be reported as fixed, which makes me think "whats the point of me supplying a bug report then?".

    I will hapily submit a bug report but it looks like it will be just set to "fixed" as according to issue tracker this issue is "fixed" despite many users reporting sporadic issues with it still for last 6 months.

    Which specific error are you getting? The cases that say are fixed on the issue tracker are fixed, and covered by automated tests. Could you give a link to an issue that says fixed but actually isn't?
