    Well it seems i solved the problem.

    I removed the Android.dll here "obj\Release\90\Ouderijn.Android.dll;obj\Release\90\Ouderijn.Android.dll"

    And when i build there is a new one and no problem anymore .

    The problem is that i dont know where to look .

    Does not matter what i open every time the error.

    Open Properties ,then error.

    Build , then error.

    Open Xaml page , then error.

    Or add new page or existing what ever , always the error.

    It is an app that i made and is in test fase in Playstore , when adding something that does not work or is nice then after some test i remove the project and put the original from a external harddrive back.

    Maybe there is the problem coming from ?????

    @Borisoprit

    (1) Have you restarted Visual Studio?
    (2) Have you rebooted your PC?
    (3) If you create a new solution using the "Mobile App (Xamarin.Forms)" template, do you get the same error? If so, you'll probably need to repair your Visual Studio installation.

    Still working on the error and found this now.

    do i have to remove something , build or rebuild is not working anymore

    "obj\Release\90\Ouderijn.Android.dll;obj\Release\90\Ouderijn.Android.dll" is an invalid value for the "OutputAssembly" parameter of the "Csc" task. Multiple items cannot be passed into a parameter of type "Microsoft.Build.Framework.ITaskItem". Ouderijn.Android
