我正在尝试将具有三种不同语言的程序从VS2008升级到VS2015，并运行警告MSB3277，这是mscorlib的两个不同版本之间的冲突。语言：本机C / C ++静态库，C ++ / CLI程序集，两个C＃程序集和一个最终的C＃exe。
似乎本机C / C ++和C ++ / CLI都可以正常编译。问题出在编译C＃exe以及MSB3277时，它看不到C ++ / CLI中定义的命名空间之一。我的理论是mscorlib问题在C ++ / CLI和C＃代码之间，导致找不到命名空间。
这是我打开详细日志记录时所得到的。在我看来，.Net 4.0的第三方库仍在使用mscorlib的.Net v2，对吗？如果是这样，我该如何解决？
