Ao atualizar projetos com pacotes nuget do Vx20XX para o VS2015, você pode ter um problema com os pacotes nuget.
Exemplo de mensagem de erro: Este projeto faz referência aos pacotes NuGet que estão faltando neste computador. Ative a Restauração do pacote NuGet para baixá-los.
Atualização 06-02-2016: eu tinha um link para as informações, mas elas não funcionam mais. Eu suspeito que um caminho recente resolveu o problema ??
Corrigi o meu problema ao escrever um pequeno programa que faz a restauração de pacotes MSBuild-Integrated vs. Restauração automática de pacotes
Você pode baixar o executável da ferramenta aqui .
Por favor, deixe-me saber o resultado :-)!
