Question

我有一个用于构建nuget分发项目的msbuild。它构建了我的程序集的.net 3.5，.net 4.0和.net 4.5目标版本，以便于打包。在Windows上，这总是很好用，但是现在我使用xbuild进行单声道操作，除了.NET 3.5目标版本外，一切正常。

我收到类似

的错误

不确定我缺少什么，因为程序集对所有其他目标都是可读的。

确定，文件确实存在

编辑：

有趣的是，我实际上在Xamarin Studio中将我的项目定位到.NET 3.5时遇到了同样的错误。我不确定这是不是一个错误，或者其他东西是否发生了变化，这不应该起作用。

IIRC最新版本的开源F＃编译器（在github上托管的版本）默认为.NET 4.0。您需要自己编译F＃以调整构建，以允许它安装必要的.NET 3.5位。

Xbuild构建面向.NET 3.5的F＃3
