    You can try to check if there is some problem in the layout, if there is any problem with layout, it will cause such problem.

    If the problem still persist, you can try to delete the bin folders and the obj folders and rebuild it . If it doesn’t work ,try to restart the VS .

    Besides,sometimes even if the APP is built successfully, the code will also get a red error message and you just ignore it.

    I've already tried cleaning, building, rebuilding the code, close and open the project, and nothing seems to work, basically i already tried all of what you guys mentioned and nothing seems to work :/

    When I built your app , I found there are several problems:
    1. the layout below is not well-format

          android:text="Registro de Estudiantes"

    Note: change android:layout_marginLeft"180px" to android:layout_marginLeft="180px"
    2. after modified the layout ,then I found the errors below

    So I just uninstalled the Nuget:LiveXAML, after uninstalled the nuget, the app will been rebuilt successfully.
