    Hey I am trying to build the ARcoreExample provided here :

    https://developers.google.com/ar/develop/unity/getting-started

    I followed all of the steps and am getting two compilation errors and for the life of me I cannot figure them out.

    #1:
    TypeLoadException: Could not load type 'UnityEngine.XR.Tango.NativeImage' from assembly 'UnityEngine, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'.
    System.Reflection.MonoMethodInfo.GetMethodInfo (IntPtr handle) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.Reflection/MonoMethod.cs:59)
    System.Reflection.MonoMethodInfo.GetAttributes (IntPtr handle) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.Reflection/MonoMethod.cs:75)
    System.Reflection.MonoMethod.get_Attributes () (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.Reflection/MonoMethod.cs:245)
    System.Reflection.MethodBase.get_IsSpecialName () (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.Reflection/MethodBase.cs:184)
    UnityEditor.Build.BuildPipelineInterfaces.InitializeBuildCallbacks (BuildCallbacks findFlags) (at C:/buildslave/unity/build/Editor/Mono/BuildPipeline/BuildPipelineInterfaces.cs:191)
    UnityEngine.GUIUtility:processEvent(Int32, IntPtr)

    #2:
    Error building Player: TypeLoadException: Could not load type 'UnityEngine.XR.Tango.NativeImage' from assembly 'UnityEngine, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'.

    Any help or tips of what direction to go in would be amazing, i am using the newest beta build for unity as well.

    Thanks!

    FIXED:

    sdk mappings got removed with some other instillation, unity did not prompt me for this

    Could be the latest beta thats broken, check your SDK's... We eventually got it to build but it crashes on launch :/

    Yes, confirmed that going back to 2017.2.0f1 has removed the error from the console. Thanks both of you!

    Always the same, "or latest beta" , but NO YOU SHOULDNT because the latest beta does never work properly.

    Had exactly that, saw on the first message of the official topic 'Latest Beta' and..... yeah I found this thread. Awesome!!!
    And then you go to the beta page and yes..... the version they talk about is removed from there. Awesome again!!!
    So I guess, 2017.2.0f2 does work? Because I don't see any message anywhere about that. Awesome once more XD
