Estamos criando um plug-in do Outlook 2010 usando o VS2013, .NET4, Microsoft Async e BCL Portability (da Nuget) e encontrando erros de compilação semelhantes aessa questão eesta discussão no fórum infelizmente, nenhum desses recursos (ou o resto da Internet) ajudou a resolver nosso problema.

O erro de construção e o log do Fusion estão na parte inferior. Minha primeira pergunta:

Como solucionar um problema dessa tarefa de criação de FindRibbons? A remoção total do arquivo de destinos do VS permite que a compilação seja concluída, mas à custa de nenhum controle da faixa de opções.

O segundo sintoma que temos é oAttempting download seção do log do Fusion. A DLL é criada no nosso projetobin\Debug diretório para que a outra pesquisa de diretório seja ímpar. O que levanta minha segunda pergunta:

Existem sintomas no log do Fusion que estamos ignorando?

O último sintoma é do log de compilação detalhado, onde vemos conflitos entre o mscorlib, System.Core e algumas outras bibliotecas. Essas dependências são recebidas por meio do Bcl etc., e parece que o conflito 4.0.0.0 vs. 2.0.5.0 pode impedir uma compilação ou gerar uma FileNotFoundException. Tentamos vários remédios com redirecionamento de ligação, etc., mas não conseguimos fazer isso funcionar. Então, última pergunta:

Soluções ou dicas de solução de problemas para esta versão criam conflito?

Muito obrigado antecipadamente. Desculpe pelo comprimento.

Como prometido, a falha de compilação:

Error    1    The "FindRibbons" task failed unexpectedly.

E o trecho de conflito da versão de compilação:
