Al actualizar proyectos con paquetes nuget de Vx20XX a VS2015, es posible que tenga un problema con los paquetes nuget.
Ejemplo de mensaje de error: Este proyecto hace referencia a los paquetes NuGet que faltan en esta computadora. Habilite NuGet Package Restore para descargarlos.
Actualización 2016-02-06: tenía un enlace a la información pero ya no funciona. Sospecho que una ruta reciente ha resuelto el problema?
Solucioné mi problema escribiendo un pequeño programa que realiza la restauración del paquete integrado MSBuild vs. Restauración automática del paquete
Puede descargar el ejecutable de la herramienta aquí .
Por favor déjame saber el resultado :-) !
